Hi, we have 6 strains growing at the mo, and apart from the NLXBB which doesn't like as much of the nutes as the other strains,only half the strangth, they (Skunk#1, Skunk Haze, Hash Plant, AK48 and PPP) are all fed the same strength veg nutes, admittedley they were all started from seed at same time so all the same age, but now some are in flower room and some are still vegging, so at the mo i'm just writing everything down, so i know what strength flower nutes to give the once in 12/12, then give the same to the vegging plants, once they go into 12/12. Same with the clones i have.
I just find writing everything down does help, cos you will lose track of what gets fed what and when, and the dates they went into 12/12, l was working out my next 3 month harvesting dates, lookes like i'll be busy harvesting every week, which is nice, but all that trimming, yak !
