Which deficiency is this now?

[BlueBerryMango]

Which deff is this now?
P??

Ways to fix it so it doesn't die, what usually causes this.
Stems are purple, new growth stems come green then slowly become purple.
The other leaf took a bit more damage.
Slow/no growth.
Organic soil, perlite.
Feed roughly 6.5-6.6ph
Roots seemed to be a healthy white when I moved them from the smaller pots to the larger pots with more perlite to help the drainage issue.

Almost 99% sure this is a p deficiency, locked down from a to high of PH in the root zone, etc...

when I start it's about 7.2-7.4 in the morning, eventually my run off becomes a ph of 6.7-6.8 after about 1/2Gal of run off has been produced, wait to the next day to allow for drying of the soil, the ph then has risen back up a bit.
The ph has come down from about 8.0 according to the ph strips to confirm & ph pen for fast reading when it first got put in the pot almost a week ago. But I always stopped watering it when the ph run off became 6.8 or slightly lower, it's taking less water to bring the ph down and it doesn't seem to be raising up as fast.



Again, similar to this little one happened but it was under CFL along with 2 others which have sense died due to no recovery and this one has seemed to somewhat recover, it's in the same soil mix as the bigger one that was doing well, the ph in this pot dropped fast, and stayed down without raising up, same water feeding, new growth tips becoming yellowed, hasn't seemed to grown. But I keep this one under LED now and the larger one under the 230W CFL bar.

However I'm not sure what's causing this plant to not grow if I've been able to maintain the ph in this pot around 6.5-6.8

Tldr: but did see you mentioned a half gallon runoff?!?! Youre drowning it ffs. Mj doesnt do well when overwatered in soil..you are sufficating the roots and then no uptake of nutes. I wouldnt give it a half a gallon water till its alot bigger..like 8x that size on a hot day in the sun...

Not really the problem kinda started in a smaller pot which it was actually doing really well in see. First this is a 2Gal pot. Lots of perlite and some soil, Fast drainage, dries fast enough I do this once a day. And it's 1-2 L of run off I make. Roughly 20-30% run off

I had to close the closet door for a day but I changed the light timing to be off during that time, I should have kept it off an extra few hours or the entire time, but the lights came on for about 2 hours and the plant started looking like heat stress but i don't think it is.

Had to get new soil so I did, because these pots were running off at ph5.7-5.5 and taking 3-5 minutes to drain out alittle of water, so they had to be repotted anyways, the thing is it was showing signs of P efficiency even in the previous pot, purple stems, but it could have been early stage and now it's mid stage.


Also I have an air pump for oxygenating the water, not really sure if it really helps in soil or not but either way.

Honestly, it looks like you hit them with nutes too hard too early, what did you feed them? I don't see P def anywhere.

You can stop with the pH also,it's not needed if you are truly organic. A 1 gallon pot shouldn't really be getting any more then 1/6 - 1/4 (2-4 cups) a gallon during waterings.

Post up your soil mix & what you feed.


That purple looks like genetics to me. I have a cut that does it everytime in veg.

 

[HarryCooter]

Your plants look healthy other than burnt tips. Burnt tips should always make you consider excess nitrogen regardless if you have fertilized or not.

Here is how I would approach this: Lets assume it is nitrogen burn, I would back off roots fed nutes for atleast a week to let my plants recover. But, I would foliar feed calmag and microblast. This way all bases are covered. If you have nitrogen burn than you have allowed your plants to recover, but it was a deficiency you would have addressed by foliar feeding which is a very quick recovery.

Well wouldnt tap water that's above 7.0 need to be dropped to feed/water them?
Also I haven't feed sense putting them in the larger pot.


Soil I found in stores basically, says it's organic, contains alapha meal, bone meal, earthworm castings and kelp meal...not sure if there's more but has some perlite in it and added 1 scoop to 2 scoops soil.
The soil I been using for 2-3 months now is acidic, not so organic.... I mixed a bit of that into it to help with the high PH, I can't be told by 2 different people ph matters then ph doesn't.
But I've been going on with these same plants for 2-3 months surprising without starting over from seed. Get them large enough to clone, something happens to it, it dies, the clone takes its place I get alittle further with the plant.
It honestly could even just be the strain I got currently...I've heard it's a very picky strain, sometimes hard to grow, it even mentions it's more moderate then easy, which i didn't know until I got home from buying the seeds.
I'm trying to grow "Crown Royale" Indica, and it's a cross of purple kush and Blueberry which happen to be 2 of my favourite strains. So I was thinking it's just genetics and nothing to worry about but the leaf ended up getting those spots.

Also I feed General Hydro, bloom, grow, micro. Instructions on the back 1tea/gallon. But I make alittle over 1gal, ppm isn't more than 800 according to this one pen, then it's alittle different according to this other pen I got.... but it says the EC is about 790US/CM which if I looked it up right converts to 0.8 EC. It could be alittle strong but the stem itself is actually pretty long at least 7-8 inches and this is usually where I'll start getting problems and a new clone comes along...
Also a very little bit of Cal/mag sense my water is kinda on the harder side with cal/mag in it already.

I'm waiting for 1 thing to show up here so I can make distilled water all the time. Which is almost as good as RO, so that should help a lot with proper feeding and such then.

You don't need to add any nutrients with that soil. It's already 'hot'.

Small plants got fried, elements are reacting, antagonizing each other causing lockout, and you see deficiency, then add more, compounding the problem.

I agree that he is watering too often but not that he is watering too much. There is almost no way to over water in a fabric pot as long as you let it dry out between watering.

sure there is, especially if excess water is used to flush out all the beneficial organisms and nutrients and fungal activity in the soil every time its watered every day with 2 litres of run off=ill habits=ill finishes

 

[MonkeyPickAss]

He is 100% watering too often no doubt about that. 2l of runoff is just ridiculous.

Ok then. Sounds like you know everything.
There is no nute burn at all..the biggest leaf on that plant..look at the tip in the middle..its curling down..that means overwatering. You are going to get all kinds of deficiencies when you overwater..keep giving that plant all that water..it wont last another 2wks like that

 

[BlueBerryMango]

Guys it's UP TO 2L it doesn't even reach past 1.5L honestly cause I measure just over 1L in run off. I'm only giving you quick rough estimates, this is kinda the first time I put something in a pot this big.

Could be over water but again when I touch the top of the soil it's dry at least 1 inch+ from the top (without measuring) and the fabric pot is dry to the touch where it actually takes me to dump 2L to produce the required 10-15% run off but because it keeps dripping out it starts to produce the extra 5%.
I could cut it back and dump 1L water in it, and if the soil is organic enough to survive with no additional nutes, I'll cut those out and stick with watering until I see signs of deficiencies, you know give it that boost.

I also woke up this morning and the pant seems to be in the exact same state as it was when I went to bed, no extra droopage. Etc. Looks like it COULD recover eventually.
I haven't watered it this morning like I normally would have, I'll let the pot dry out for 36-48 hours and slowly water it again. Measure out 750ml dump it, let it run off and leave it. Ill still PH The water cause I heard you still should ph WHAT YOU DUMP IN, even if it's plain jane water..

lift a pot filled when dry, note the weight and feel of a dry pot. now water the pot with about 1/4 of the pot volume in water. all at once.
now dont repeat until you feel that light pot again. gravity pulls water down from the top with vacuum'd air, top dries first bottom is wet.
perfect amount of water is when none comes out but bottom is wetted. you'll get the feel for the right amount for you.

Don't have a good scale for that right now. I'll just cut back on watering, all though if it takes 2-4* days to dry out fully normal then and not considered "slow"?

*4 days being max with full dryness beyond the 2inch requirement or completely dry no water left

 

[chemphlegm]

i use five gallon pots and yes in veg four days is about right if the plant is bigger and in flower when finishing
or transitioning could be four days too. I have 70 or so plant buckets and dont use a scale, I use my foot, like a kick/tip, sometimes I use the spray nozzle on my watering wand to tip the bucket and feel the weight.

 

[boilingoil]

If you're pouring 1 1/2 liters in a 5 gallon pot and getting run-off you are over watering.

 

[Johnei]

A little wilt is ok, when figuring out your watering schedule for your future with that plant.
Plant will come back like it never happened once watered. And then you know the approx. time that is perfect to water.
Overwatering is not as forgiving and will fuck up your plants quick.

I will not water my plants unless I am absolutely sure, guessing game fucks up the plants.

Be afraid, Be VERY afraid to overwater. This is what I suggest you start thinking, and good things will happen.

EditAddon-- up to about 25% runoff is fine with every watering to control any buildup, and keep pH stable in the medium, not relying only on the soil's buffering abilities. But, if you can achieve the same result with less runoff, it's always better of course and no need to waste nutrients and water for a diminishing result when less could of gave the same result.

It's best not to guess,
run some small tests,
to figure out if you could be using less,
now I need some rest.

lol

Good Growing bud

 

[chemphlegm]

When pail is light and dry I water with one gallon of water to four gallons of pro mix in a five gallon pail with little to no run off.
when harvested I see no "dry spots" in the soil plug.

Way over thinking it imho, look for this book and read it completely.

You'll learn why pH swings the way it does and much more. Apply what you've learn from it to your grows and you'll stop having problems.

no its not. what type of "buildup" do you think is happening in an organic soil build anyways?
25% run off is over watering. How wil over watering help to keep ph stable in this organic soil build?
