First off I should say I used miracle grow maybe 2 - 3 times during veg but then read it was no good for MJ so since then they've been getting nothing but cold tap water. Heres a couple pics of my biggest of 4 plants. Vegged under 5000k fluros for about 2 months (too long I know) and have been under a 250hps at 12/12 for 3 weeks. Basically all I have done to these plants is give them water and light. Havent messed with PH or ferts or anything. I'm not doing it for profit or even personal consumption really, just for fun, so whatever happens happens. Considering that I think they're doing pretty damn well. Anyway she is. Leaves are starting to go light green/yellow and they've got brown spots on them. Time to give my baby some love I think. Any suggestions on fertilizer or anything else much appreciated.
