4 Strain, Mainline 4x4

just continuing along, some plants are looking better than others, the slower plants I'm doing a slightly different mainline style than the other 2 just to try and keep them ready for flowering around the same time. I think i have most of them to the amount of mains i want, going to let them grow out a bit more than toss in flower tent. Going to continue with the microbes about once a week, week and a half, I cant say I'm noticing any difference so far but not seeing any negative effects either so going to continue using it for now.
