In Coco smart pots .
DIY feed.
Plants are 2 wks into flower , showing typical N toxicity signs dark glossy cupping which happened over the last 48 hr
Been using Fulvic for about 4 days . kept the same 600 ppm value in the tank just added fulvic acid.
What I did was lower the nut strength to 300 ppm and flushed then set the nutrient tank to 300pm, am also drying them out to see if its any over water issues which I dont it is they well developed root systems.
My question is can Fulvic acid cause nut burn like this as I also noticed just the very leaf tips burned only about a 1/8 inch.
And Im thinking my feed may be a little N hot , which is the B part which in this formula is straight Cal Nitrate at the rate of 1000grams into 4 1/2 liters,
Can I lower the Nitrogen by having a little less B of the two part mix , will that also cause other problems lowering the calcium .
Didnt seem to have any problems until the fulvic was used, can I just lower the ppms and that will fix the Nitrogen toxicity.
Cheers
