I waited that long this time because, first I start with a solo cup, then I transplanted to a 3 gallon pot, and now it's in its final home which is a 5 gallon pot. Every time I transplanted I used new soil which I believe has what my plant needs for the first 4 weeks then after that you need nutrients because the plant has used up all the nutrients the soil has. Also because my plant didn't show any signs of deficiency. I try to copy the way Nebula Haze grows and she says to only add nutes if plant show deficiencies. This is only my second grow the first time I only vegged for 1 month this time 2 months and like I said I didn't need nutes until the second month and I believe it was because the way I transplanted the 1 st time I used nutes after 4 weeks because I only transplanted once so the nutes in my soil where already used up by then I went from solo cup to 3 gallon pot. I'm growing feminized photo from Nirvana northern light. It supposed to be good for beginners and it really doesn't smell a lot like marijuana so I went for it because I don't use carbon filter. Soon I will post pics of how my plant looks right now.
