hi!
could someone pls help me with the problem im facing.
i believe its a potassium lockout.
im feeding only maxibloom currently as earlier i was adding cal nit and epsom which only aggravated the problem. my coco has been buffered with 15ml/gal of calmag and maxibloom has enough of cal and mg i was told.
i had been feeding at ph6-6.1 twice a day but i read elsewhere that i could go as low as ph5.2. i did try and it seemed to slow down the deterioration but not totally. the inflow ec is 1200 and pretty much the same comes (around 20-40%) out as the runoff probably 50ppm more. ive read that the runoff ph isnt that important but its at ph6.4.
how could i salvage this grow? ive tried flushing a couple of times with 0.7 ec ph6 but didnt seem to help.
the leaf tips begin to get soft and then crispy. upper growth leaves and shoots are growing pretty slow and small. it begins with the lower leaves turning pale and seemingly rough to the touch.
im using ro water because my tap is pretty high. I tried mixing tap with ro water and fed only maxibloom and got a serious mag deficiency (proper yellowing and spots on leaves)
I’m using led lights but I’ve done a couple of dwc grows with the quantum boards without any issues using only maxibloom from start to finish but gave up due to root rot issues. now im facing this with coco...
