Hi bud. Looking at your diary, it seems you've been having nutrition issues for a while. Unfortunately you don't mention which BioBizz nutrients you are using nor how much and how often you are feeding. 75-98% RH humidity?? Is this correct? No matter the feeding, I can imagine humidity above 70% rh is driving her nuts. And then the PH.... you use soil and give her water ph'd to 9? PH above 7.5 can cause the roots to stop up-taking nutrients. That may be what you are experiencing. Generally, the ph of the water should be around 6.5 with runoff no higher than 7.5 Or is there a reason you run the water so high?

Grey leaf tips Booth plants are showing some kinds of burn and I am not sure if it is nutrient burn or light burn or if there is something missing. Looks a bit like MG deficite but shouldn't the plant take that from the soil in that state and age?

Pest infestation left my plant folded and weak. I treated it, but now blacked out leaves?Ants were farming an oval shaped bug's secretions that was eating my stem and going underground, leaving a trail of a film-like substance. Treated it with neem oil, cigarette butt tea, garlic and dishwasher soap to fend them off. Black leaves now. Tips?

Black spots on leaves Black spots present on some fan leaves. During ~3rd month right now. Watering with HESI in Coco Coir, PH ~6 every time, 1/2 runoff water. For about 2 weeks prior to this, I also added very small amount of kelp powder. Soil seems fine.

Weed doctors to the rescue Day 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏

I keep loosing leaves to some sort of nasty necrosis. It affects leaves at all levels, small and big randomly. I had to remove a lot of dying foliage At first it looks like a asymmetrical spot of leaf starting to thin out to lighter color then tissue dries and turn black. I have high runoff EC3.3 and I blame Easy boost pellets because I only add rootjuice 1ml/L and sugar royal 0.5ml/L to my water. What is it and how I fix it?

What to do? → BF Runtz Auto - Day 42 - RH70, 80F in BioBizz Light Soil On my last post, I was advised I have N tox, so I watered w/o BioGrow, just BioBloom and it's gotten much worse. The runoff EC was 1.5 (watered with 0.8, runoff pH was okay), so I’m guessing it's salt buildup. I plan to flush when this watering dries out—any thoughts?

Leaves are turning into dark green with a plastic-like texture I have 3 ladies in my tent. While the others looking healthy, one of them has a darker green tone with a texture like plastic and shiny. Everything is the same (fertilizer ratio, coco medium), however the one on the picture has a problem. What might be the problem folks? 😩
