We need to know what soil you're in. What you've been feeding and at what ph if you check. Also, what is the white powder on the buds and other plant? It looks like horrible powdery mildew but I'm guessing it's something you put down. Are you growing them outside? Otherwise, it's impossible to give you any real advice.
First off that white powder is diatomaceous earth. I had a pest infestation that had to be taken care of. As for the soil I have them in Fox Farm Ocean Forest. They're being grown indoors underneath an Aglex k4000 LED light inside a 4x8 foot tent. I am using Foxfarm big bloom nutrients at 650 ppm with a PH of 5.9.
Your in soil the ph of the water should be 6.5-7.5 normally you don’t need to ph the water for soil grows if your using tap water. I would raise your ph next watering since 5.9 is really low for soil.
What pests were you dealing with?
Glad they are bouncing back. Send some of that sunny weather my way. Winter is fast approaching here in upstate NY.
I've been flushing the last two waterings and I'm not seeing them getting worse, but I can't see any improvements either. I am growing in Fox Farm Ocean Forest soil.
Based on that photo and the clawed leaves, you may be overwatering. Why do you think you need to flush?. No need to use Big Bloom, you do want to use Tiger Bloom and you WILL want to PH that. Big Bloom isn't really a nute, it's microbes for the soil.
Try going by weight of the pot just pick it up a little bit to feel how heavy it is after you water then let it get pretty light before watering again. Also your in soil no need to be flooding it just give it a good drink without saturating the soil these plants seem to really like the wet dry cycles and the plant will tell you when it’s thirsty it will start to sag and just look unhappy and even then it’s not like it’s just going to up and die within minutes they can go some time without water.
Even if your tap PH is 8.5? Btw, way better avatar!
Yeah.. my tap runs in the 8's .. if its primarily a peat base soil with time release nute in it then id ph to 6.5-7 .. nothing lower then 6.5 ..
