Looks pretty good, it's always a good idea to flush your soil every couple weeks,whether you're using organix or chems. This just ensurres that any nasty buildup gets removed. Are you planning on repotting? Those lil 1 gal pots are nice for a while, but pretty soon your plants will get top heavy and need to be supported. Plus they inhibit root growth after a while. I'd reccomed getting a coupld 5 gal pots or even 10 gal buckets. If you decide to go this route, get some worm castings and mix them in with the soil, that'll help soften the transition and help feed your plant during flowering, when you should use minimal ferts, except a bloom fert that is.
