I use lucas formula..
I use maxibloom-7 grams per gallon mixed with sum silica and cal mag.
Gonna use great white this time when transplanting see how that goes.
Ive onfly used lucas formula on one harvest. Had no probs what so ever til late flowering i had a cal mag def but i cleared it up.
In the bigging i used ro water then i would use tap and let it sit over night and then i switched to just using tap right away. Never hurt a thing but my ppm went up. I remember i wouldnt be usuing the whole 7 gams when they were still tiny. But my end ppm was like 1700.
I liked the easiness of the formula and it does show great results but i want to run it again with sum killer clones i just got see the results and then i wanna try and take it up a notch with the nute line up.
Ps the harvest i just did i smoked a j of it for the firs time yesterday and it was a unbeiliveable head high. I pulled at 10%amber trichs. I hate the smell of it but it got me faded like it was sum kush so i cant be disappointed.
