good morning Grande those girls look great .personally I think they are old/big enough to plant into the pots they will grow in , after you transplant them give them a couple of feedings with voodoo juice (kinda expensive but worth it) it really gets the roots into overdrive.I can only give ideas about what works for me so here is my grow schedule .I transplant seedling or clones into 1 gallon pots for two weeks giving them grow (weak mix) and voodoo juice (half strength) then I transplant them again into 5 gallon pots where they live until harvest . At this point I increase the nutes and water amounts. I like to keep my plants on a 3 day watering schedule . so I only give them enough for that amount of time. if you water with nutes and just water every other watering you can feed them heavily and then the water washes out the extra nutes. so far its worked for me. most of this is trial and error ,but with the help of the forum maybe we can cut the error down lol .Just remember there is 6 ways to do one thing so what feels right to you is what counts.
