Well honestly its got me banging my head off the wall! Im over feeding these girl.. Wisher told me cut the calmag out and i did and they look even more N tox.. Now i got some downward curled tips is all. I dont see too much more effect from it. My ec was 1.3. when I took the calmag out it did take more grow to get to 1.3, so i just watered it down to 1.0... will keep monitoring.. Some plants dont show tox, some due.. maybe diff in pheno? A lot to learn from these plants.. I got my eye on one of the kushes tho.. She seems to really grow the way i like. The branches seem to grow out and up, instead of all bunched up.. It like its naturally bushing out.. I will watch her, that lil huzzy just might become my main hoe :)
