PH issue or pest/disease or nutrient deficiency?
NY_Gashousestarted grow question 2 years ago
Opened the tent up yesterday and noticed some burning and unusual spots on a few leaves. Plant is 3 weeks old today, I water with nutrients every other day and plain PH water on days I do not water with nutrients. Growing in coco coir, I aim for 6.5 ph water

Grannie doesn't know where she talks about.
Your problem is that coco is a hydrophonic medium and for that you need to water the plants with pH 5.8
I would give them pH 5.5 the first time and give double the water that you did before to make the medium more acid.
Afther that just give the same amount as you did before already and give pH 5.8
Happy Growing! š

Your pH should be lower in coco I ph at at 5.9 until later in the grow during flower then I ph to 6.2 no higher

There's a lot more information we need in order to try to help you with this.. to ME it looks like there are a couple of things going on - heat stress (leaves curling) and the beginnings of a calcium deficiency - but we need a diary to really tell us what's going on... so go start one and come back to ask your question again please!
Good luck

Burned tips and white spotsHi, I have a auto plant in its 7th week. Today I noticed that it has burned tips. The white spots have been there for longer, I dont know if they are related to the same problem.
Im new to this and what I came up with is that the white spots could be a cal defincentcy?

Heatlight stress?Can someone tell, are these brownish tips the sign of the heat stress or something else? And how bad is that for the plant's not so distant future?
She grows indoors. Peak DLI was almost 60 but very briefly about one night. Now it's dimmed to 40dli/~600ppfd/ 20/4 schedule.

Maybe PH Lockout?Hello everyone, can you maybe help me? My Black Cherry Punch has some kind of problem. I suspect itās a nutrient lockout caused by the pH value. I flushed it two days ago, and the drain had a PPM of 1000 and a pH of 7. The plants are at the beginning of the 2nd week of flowering.

Root rot or pH imbalance?This blueberry muffin (f) plant was doing well until last week when it started deteriorating. Its grown on a mix of cocopeat, vermicompost, perlite mix and fed on compost tea and cal-mag mix. I might put it down eventually but I checked the pH and it was 5!
