If you want no stretch in the first of flower then you need bushmaster. The stretch was causing me to have more than two feet deep of a canopy and even a 1000 watts does not penetrate beyond that. I tried it and now I'm hooked. No stretch and starts to flower quicker and fill out. I don't think you can get that by changing the nutes very much. At least I could not and then advised not to screw with much because bigger brains than I had worked the nutes out. Sorry just medicated and rambling. Will check back for pic's
