hey brothers ... could you suggest me the right ra...

i'd fertilized every other time, unless i see darkness. if so, dial back so it recovers, then resume at 1/3 feedings. just as MiG says... fully saturate with runoff, check weight... feel weight when top 1" dries. recognize both with familiarity. the plants will drink more as teh roots grow, of course. So, you'll notice it may require 2x as much in same time period within a few weeks. plant size vs pot size wil dictate how often you fertilize too... without pot full of roots, it is only going to build up dangerous levesl of nutrients where roots do not exist, if too oversided for too long.
