What deficiency?

Hi all, my plants are showing some signs of a deficiency or toxicity but i cannot work out what.

Im a total noobs so sorry if it is obvious

Setup:
400w hps/mh
4" fan
bio bizz light mix soil and grow & bloom nutes

Plants:
Female seeds C99
9 weeks old - 2.5 weeks into flower
1 small bushy pheno (Female)
3 stretcher lanky pheno (balls, pistils and balls with pistils on all 3)

Watering:
i am currently watering once they look a little limp which is about every 2 days now ( room has low humidity). i have been using grow 2ml/L up to week 7.5 and then 1ml/L grow & 1ml/L bloom until the last feed. Last feed about 2 days ago was 1ml/L grow and 2ml/L bloom. I used more water that feed as they had got quite dry.

I will be getting some Epsom salt tomorrow ready for next week and will use 3ml/L bloom too.

The Problem:

Plants have been looking ok lately after a few mistakes (apart from the balls). I have been removing the balls today and noticed i have some leaves that are looking very pale, some that are yellow from the base of the leaf and the main vein out to the edges, some that are just all yellow, some that are deaded and some with burn leaf tips like nute burn. I had some of the bottom leaves yellow and die, I thought this was normal and just due to the canopy but i guess its not normal. It has started at the bottom and is now causing problems to the middle of the plants now, the top looks healthy enough to me but as stated earlier i am a new grower so i could be wrong.

here are some pics:

Day 18 of flower overall


The plant I am using for example



Some leaves that fell off or i removed to photo

leaf 1- pale, yellowing from base and vein outwards


Leaf 2 -Ends burnt away/ curled up to nothing



Leaf 3 - Just looks very ill



some of the worst affected areas on the plant





Thanks for any help

By the sounds and looks of it, I would say you are letting them dry up too much in between watering. The balls could be due to light leak during dark hours or the stress of drying up all the time. How much water per plant do you give them when they do get water?

what type water are you using and do you ph test after mixing your nutrients in ,what are your ppm and ec reading after mixing just curious,that sativa and if im correct you said your were in week 7 of flower,sativa takes a lot longer to finish but i dont think your any were near the cannibalism stage,have you checked your soil ph or your runoff

He needs some answers this doesnt look good, anyone know? My plants 15 days old not pushing it for myself ( ;

Post all information you can, itll help the pros figure it out

with respect I wouldn't be doing ph etc, your using a very good organic soil and nute range that as long as your using say tap water and you let it sit for a day or two before you mix up does not need it your soil will buffer, the problem with some organics is when you add chems you throw the balance of the soil out, hence you get probs/difecencies, your in light soil so I would have used the alga-mic as well and blackstrap mollases these not only give a tonic to the plant they also feed the micro herd in your soil keeping a good balance which allows the nutes to be prepared better for the plant to uptake, they also help with deficiencies as they contain mag etc, I was never thrilled with bio heaven or top max etc but the basic things work well, remember in organics your feeding the soil and not the plant as such so it's important to get that right, it does look like your underwatering, so try to get on top of that next run, Google oldtimers bio biz schedule, you'll get good results, I used to use bio biz and I think it's great but now use pm oldtimers and no longer get the difecencies results a bout the same but health is so much better, but everyone's different, I'd stick with bio and get used to growing if you chop and change too much you won't get to see what.does what

Forgot to say, run with the epsoms don't overdo it but get it into them now, also how far are your lights from canapy? And what are your temps, don't worry about low humidity that's normally good for flowering, whilst your having these problems you've got further then a lot of people and even if you see it through and they've hermied on ya its experience, and I'm sure you won't make the same mistakes, also try to get close up of these balls in a photo,

you can tell him all that shit you want but he aint gonna no shit unless he no's what the soil ph is and which way to go with it

Im pretty sure all this damage is from the stress of underwatering. They dont like to go limp from lack of water, it causes stress and its showing in you leaves. Keep feeding as scheduled. Sativas are a fussy one...must treat them right

He knows his soils ph, it's on the side of his bag lol, as he's been using bio biz nutes that would not really of changed unless he's using shit water, hence I asked what water he's using, he's not said he's used anything chemical to alter that, that's what I've found after using bio biz myself it wasn't a dig at what you've said, I'd agree more with the underwatering than ph etc that's all, and everyone knows about the deficiencies with bio biz especially if your in the uk, I haven't phed for a couple of years with no difference, and loads of organic growers don't, they leave ec etc for scientists lol, I'm not clever enough for that, suppose we all talk shit in one way or another, next you'll be saying to test his run off lol

looks like something is going on there.

Low humidity while flowering is not a factor during the last two weeks,it even helps produce frostier buds apparently. Humidity should remain above 40% before that. I have noticed that my winter harvests(low humidity) will tend to be more sensitive to heat stress. It's important to keep that light at a good distance from the tops when humidity gets low or your tops will dry out and yield will be greatly affected.

That's food for thought. though I like to be below 50 per cent with good air flow in flower, normally as I verge on overcrowding lol, and touch wood never had mold etc, never knew about the last two weeks so thanks for that, I was thinking the same thing about distance of light as I asked the op, I just think that with his lower growth it looks like underwatering and perhaps weak light/air flow

Yea those plants desperately need more water, I think he is afraid of over-watering.

hey guys thanks for the all the advice and input im pleased i posted here now as i have been on other forums in the past and its more stressful than helpful.

Told you it would probably be obvious, i think it is under watering, ive now researched that and found pics exactly the same as mine(how dumb do i feel now.....plants need water duh). I watered about 20 mins as the top leaves are now drooping and showing classic signs of under water(still think over and under look the same from pics....i obviously haven't seen that because i am under watering)

I am afraid of over watering as i am over feeding. The vibe i get from most new growers is that they meddle too much and cause more problems than they solve.

I havent checked the PH as i leave my water to stand for over 24 hrs and i am using organic soil and nutes, i bought a ph meter but then read about the 'micro-herd' so i thought it was better to leave it rather then complicate matters or create new problems. However if this is wrong i will start testing it.

I am luckily not 7 weeks in to flower or i would be very disappointed, i am currently on day 19 of flower so iam about where i expected to be ....well thats a lie- i expected to of killed at least 1 by now.

unfortunately i have picked the pods off as i was getting worried i may pollinate my only true female left. i know this will probably happen anyway but positive thinking and all that shabazz .
inside the pods had nanners but they were all green and some just had loads of white pistils. Would a light leak in veg cause this as i left a gap at the bottom of my door during veg due to the incredible heat coming of the MH(that really surprised me how hot it got) . i have resealed the light leak before flowering and its only preflowers which i cannot find much info about.

Temps are roughly 27-28 deg c - 80-82 deg f whilst the lights are on, god knows what they are when cold as i am too worried to open the door and let light in during sleepy time.

Hope i have covered everything.

Thanks a lot again guys, i feel more confident now i know i can get some sound advice.

Oh yeah my lights are 2ft from the light

Glad you feel happier now, best with light leaks to be totally pro active, in fact the less stress you give including over/underwatering the better, like the attitude of gonna see it through, up to you with the ph but unless your using dodgy water then you'll be ok, do have a look at oldtimers info on bio bizz, when you got a tenner get a temp metre so you can check the difference between lights on or off you don't want massive differences especially in flower, unless your going for colour!! And to be honest this site is full of helpful people, I'd have given up long ago without the help I've had here, just some people don't allways express it right,,,

i have seen this a million times be4 its old growth not needed any more sucked dry of its nutes and not getting the light it needs so it dies off is the whole plant itself suffering from this from outside of the plant in ?? or is it just the inner growth that is dieing looks to me u are about 3-4 weeks in ? so just up your feeds by a ml

like smootherpete said balls could be from light leaks they from seed sorry i hate longs posts so i dont really read them or it could just be the seed or a dud clone

it is working the way up from the bottom to the middle. i believe the main problem was the under watering as today the middle leaves that were drooping so bad they were touching the soil are now back in the middle and looking 100% more healthy. They have also had a little more growth last night.

The pollen sacks that i missed/ have regrown have done quite a bit, they have either:
lost half the outer sheath (kind of like a membrane) and showing green nanners
split open and thrown out pistils- sometimes with a nanners inside that are green
some look like they have exploded from the pollen sack tip leaving a stalk, pistils and what looks like new growth but isnt ,just a mangled mess.

A lot of the balls that look normal just fall off by lightly touching them and the ones in the bud are attached to the bud and not a stalk. The plants has been doing this since the start of 12/12.

I have some pictures of the seeds and pistils. unfortunately i am not very good with a camera so they are not the best but i will borrow my mates camera tomorrow and see if i can get any better pics.

i have also got some of the setup too.

Open pollen sack green


sack kind of exploded/membrane gone and pistils surrounding the deformed sack



Another deformed one
.


The setup - the long box thing on my door is my attempt at a 4" square light trap that is overly complicated because when i get high i think its a good idea, in practice though......




almost positive now that they will all seed but as long as i get a smoke its better than no smoke. Next time will be better.

Cheers guys and sorry for the massive posts, im high and focused lol.
