I use plagron coco a and b. There is no veg and bloom, they state that they can be used in either..... I think this is where my problem is. Everything was going smooth till week 2 of flower. basically they started showing signs of burn even on a very little feed of nutes ( 1.2ec ) I flushed, and started again. Starting low at 0.8 ec and rising it to 1.4. Now they're showing signs of tip burn again and N toxicity! I have ran these nutes at much stronger doses with no problems but not with this strain. The NPK 5-3-4 or something similar but I know the N is 5 percent..... I'm guessing in flower this is too much as every other bloom feed I have seen is between 1-2 percent N. it's annoying because they were showing signs of N toxicity so I can't up the EC but they're showing other problems now like lack of strength in the branches. The buds are falling over all over the place and I can only put it down to a lack of nutes. Obviously the more nutes a put in, the more N they're getting ( too much N ) I'm about to go and buy some bloom feed with zero N in. Would this be the right way to go before I waste my money. Is 5 percent N too much in flower and is this causing my problems? Any help would be much appreciated as I've had enough lol!!
