Ok this one has me stumped. Only plant in the room doing this. Serrated edges all turned up. At first I thought my lights were too close so I raised them up but it’s gotten worse since.

temps 25 Celsius
Humidity 50%

Ppm and ph are all good

any thoughts?

Same strain as the other plants in your grow? You're heavy into flower; I would guess a P or K deficiency and / or both. Good luck friend.

Yeah same strains. I’ve upped the P and K in the last week as it showed signs a couple weeks ago but has only gotten worse.

I can see the P issue but where are you seeing the over watering issue?
Well not sure on that one I was just throwing it out there as to why your leaves are curling potentially. I haven’t seen leaves curl like that personally so I’m not too sure on that one.

reason I asked is because I see no signs of over watering and was wondering if you seen something I never is all.

Nope not specifically. Any ideas on the curling?
I thought over watering signs were leaves curling down not up? I could be wrong though? I’m running 1 gallon pots of coco and only feeding 4 times a day as 3 wasn’t enough and they would dry out too much I found at this stage.

Overwatering with heat can cause the tips to curl up like that. But 25 degrees shouldn’t be in that range..

My best assessment is heat but you said you thought that initially so good luck in your search hahaha! I’ll be following

What are you feeding and how often it looks hydo but I'm not certain ...it kind of looks like light micro deficiency causing the p k issue I would guess cal mag was locked, but just a guess with the info I have

It’s basically a hydro run. 1 gallon pots of pure coco, feeding 4 times a day (as 3 times they were getting too dry)

ppm of feeds are 900 (tap water comes out at 200ppm)

I would compare runoff of that bad plant with what you are putting in.

are they all getting roughly the same run-off?

Ok Im guessing it was the lack of cal-mag you should be fine than just continue with feeding I always use cal mag in all my watering or I get problems, but I have spring water with only 11 ppms

Lack of calcium can cause blossom rot it affects the tops which is different than bud rot a lot of people get them confused or think they are the same thing although in a humid environment blossom rot turns into bud rot from the fungus

yeah man all getting fed for 1 minute 4 times a day with pretty much the same run off. Next feed at 2pm I will put a bucket inder this particular plant and collect the run off and check it.
