Sick Girl, she's dying.

[Punk]

The fan leaves are turning yellow with spots, started on the lower branches about 7 days ago and it's working its way up.

I just switched to 12/12 yesterday. Using 400 watt system, and I'm almost 6 weeks into this grow. I dont' have any temp issues.

Had some ph problems, but I think I've fixed those in the last few days, but it still looks like its no slowing down.

Also, the majority of all the leaves have a faded green color with darker green veins.

Some causes for yellowing of older leaves:

N - NITROGEN (N)

Pale plants, red stems, smaller growth. Rapid yellowing of lower leaves progressing up the plant. Add any chemical fertilizer containing N. Treated plants recover in about a week.

K - POTASSIUM (K)

Affected plants are usually tallest and appear to be most vigorous. Necrotic spots form on lower leaves. Red stems. Leaves appear pale or yellow. Add chemical fertilizer containing K.

Mg - MAGNESIUM (Mg)

Lower leaves yellow and may even turn white while veins remain dark green. Blades die and curl upward.

Mb - MOLYBDENUM (Mb)

Yellowing of middle leaves. Foliar feed with chemical fertilizer containing Mb.


Some causes for necrotic spotting/yellowing between veins:

Mg - MAGNESIUM (Mg)

Lower leaves yellow and may even turn white while veins remain dark green. Blades die and curl upward.

Mn - MANGANESE (Mn)

Necrotic and yellow spots form on top leaves. Mn deficiency occurs when large amounts of Mg are present in the soil. Foliar feed with any chemical fertilizer containing Mn.

It could be one or more of the above combined and it could have been caused by nute lockout/pH problems.

Good luck.

things may improve yet, a few more days of improved ph may set things right
have you been giving enough water when watering, say a good 10-20% of the water coming out of the bottom?
salt build can produce symptoms like this

 

[itsgrowinglikeaweed]

What are you growing in, and what are you feeding with?
Your plant is hungry. Either because it has nothing to eat or because the PH problems you mentioned are keeping it from eating. Maybe a little bit of both. You've got to make sure the PH is good before you go adding fertilizer or anything like that.

 

[Corbat420]

you also just kicked it into flowering, did you change the nutes over to FLOWERING nutes?? if you did your getting TOO MUCH potasium (K) and not enough nitrogen (N). this is actualy prighty common to see, seeing as when the plant goes into flowering it kills itself to produce seeds............... you can trick it by adding (N) to your flowering ferts, you'll have a bushier plant too........

like itsgrowinglikeaweed said, make sure you have a PH of 6.5-7 before you do anything........ you need around 6.8~ for perfect feeding conditions.

repot with fresh soil..... soil could be depleted, looks like a small pot its in.

I'm using all FF products, Ocean forrest soil, its brand new soil, just potted it up from a smaller container.

The problems started before the 12/12 switch. I raise bonsai tress too, so I'm quite keen on watering it when needed, they get plenty of H2O. It's gotta be a ph issue starving the girl.

I gave it a foilage spray of epsom salt at bedtime for preventative measures. I also gave it a shot of ph balanced 20-20-20 fert last night (after several days of just monitoring the ph) to see if that will help spring it back to vigor again.

I've been very light on nutes thru the whole cycle, and up until just a few days ago was using tap water that was over 8.5 ph.

That's what I'm hoping, I really can't afford the high end ph meters yet, so i went to a pool and spa and bought some of their strips and a bottle of spa up and spa down.

It stands to reason that the FF ocean forrest is PH neutral, as it says on the bag. So its whatever I'm adding to the soil, be it just tap water that's not balanced or nuted tap water that's not balanced thats causing my ph issues, is that correct?

Ya I always get a good amount out of the drainage.

hmm, sounds like most things are being done OK
test strips should work OK too, i use ph aquarium drops, about $5 but quite accurate
not sure what's in spa up and down, might work alright
have you ph'd your outflow, and what was the ph before and after adjusting?

 

[itsgrowinglikeaweed]

When you add nutes to water the ph of the water drops (becomes more acidic).
The general tendancy of soil that you are adding fertilizer to, is to become more acidic as well.
You can get a digital PH tester on Ebay for 20 beans or so. http://cgi.ebay.com/Milwaukee-pH600-Digital-pH-Tester-Meter-Pocket-Pen-New_W0QQitemZ370238910990QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item5633f5720e&_trksid=p3286.c0.m14

Spa up and down is sodium bicarbonate and sodium bisulfate. All it takes is just a dash to adjust a gallon.

I only started testing and adjusting ph a few days ago and since then, my outflow is at a normal ph apparently.

That was my thought, if you're starting off with ph nuetral soil, then whatever the ph is of what you add will be the direction the ph will go.

 

[growone]

this begins to make sense - you have a pretty alkaline water - probably fairly high TDS(total dissolved solids)
you're adding some more dissolved solids, though they do seem to help with ph
my guess is sodium salts may not help the situation
might want to consider PH Down, available at walmart for modest cost

 

[itsgrowinglikeaweed]

sodium bicarbonate and sodium bisulfate will work, but thats not what you want to use. Those are for Spas not plants. You really dont want to be adding any kind of sodium to your medium. Ph down is easy, vinegar, lemon juice, acidic stuff like that. Ph up is a little trickier but its not as called for either. Oyster shells, crushed marble, hardwood ash and yes baking soda (sodium bicarbonate) all are PH+
["if you're starting off with ph nuetral soil, then whatever the ph is of what you add will be the direction the ph will go."]
You got it.
Are you letting your tap water sit out for a few days to let the chlorine evaporate off?

I did switch to RO water this week too. with RO water and nutes, my ph drops.

You say PH up is not as called for? In all my testings, my ph dropped everytime i added nutes. Again, RO water now, but i did let the tap water sit overnight, yes. Thanks again fellas, for your prompt advice.

btw, nice gallery itsgrowinglikeaweed. It's obvious you're passionate about the this matter.

 

[growone]

sounds like you've made some good adjustments, some junk from the hard water is probably still in the soil which may be slowing the recovery, some extra flushing may help

Thanks Punk. Passion is a good word for it.
Good luck with yours.

Thank you growone, great advice. Hopefully she turns out.

if you have the ph issues taken care of let her drink the water she has, let the soil dry between watering. you are going to kill your girl by caring and loving her to much.
