thanks for your help guys i bought 2 huge ass flo bulbs from hd and they are 4200 lums each . HOWEVER. I DESPERATELY NEED HELP WITH MY NEW PROBLEM....the plant is getting brown like.....everywhere on the top....even my new little leaves sprouting on top are turnin brown....i have brown spots all over the leaves and its not growing at all....possibly my nute mix?....im usin botanicare pro and its worked great till now. The guy at the hydro store said only give it about half the recommended nute dosages....so that would be 1 tbs of grow and 1 ts of karma per gallon. Ive been using 4 gallons so the roots will be covered. I use 3 gallons of nutrient water and one gallon of regular water.....some leaves are also curling up and are brown and very soft and brittle....i cant post pics bcuz apparently the file size is too big :/
