Spring is in the air thats for sure. Even where I'm at it's starting to look nice. You do know those plants are going to be all they can be. I love being able to plant straight in soil. Plants grow as big as their roots, so that unlimited root area all thru veg and early flower, she'll fill every inch of alotted space. I've not looked into the strains your growing as in how big they can get but they should be all that plus some. I'm not sure if you amended your soil but in this situation you can sure benifit from some good old fashion organics. Stuff like blood/bone meals, bat and worm castings, plus alittle of this stuff,
Mykos :: Xtreme Gardening. I even brew a tea with their wetable powder, compost, and some molasses. Works great all te the veg cycle. But if your using a high salt based fertilizer, it destroys your microb's. What I do is not use my salt fertilizers untill I need some aggressive feedings as in mid flower. By then plants aren't really growing roots anymore they are growing flowers and root growth is secondary at best. You could use a 100% organic and continue thru-out flowering. OH well Glad to see you getting ready because spring is in the air. Happy Easter and Keepem Green
