First time DWC, day 70, 3 weeks in flower. Nasty rusty spots appear on lower leaves. Is this CalMag or else? Please help understand and fix, thank you :)I'm using TA Tripart, current EC is 1.6 - ph 5.5-6.5. Everything was smooth until week 10. Two weeks ago I started adding Plagron Power Buds and Green Sensation. Yesterday added CalMag to see if it helps, but it doesnt seem to... She drinks a lot, ph mostly goes down, EC static

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?

Problem with plants in the 3rd week of vegetation.I'm posting again because I accidentally marked it as resolved. I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

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? 😩

It looks very dark & feels soft Temps were 17-19°C & Humidity was 90%+ Water should be PH5.9, think ph reader might be wrong and ph is too low?
