Personally I’ll start by flushing my medium and check my ppm and ec to see where they at then make proper adjustments from there. After flush let plant dry then give them a feeding high in calmag and phosphorus (bloom). When mixing your nutrients make sure to mix in your calmag first.

Says soil medium in your diary but your using coco bloom? Canna a b what? Terra ? Coco? Hard to answer when we dont know whats what. If your in soil not soiless like coco or peat, then you should never have a cal/mg issue. If you do it would be to lockout where their just not taking those elements up.

Organic peat control I think my plant is being eaten but gnats and it looks like nutrient damage on it but I haven’t given ANY nutrients to it. What should I do? Can you diagnose my plant? Any remedies? I heard cayenne pepper can be used for a pesticide is there other things? Does Neem oil work well?

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?

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?

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
