Don't go nute crazy stick to KISS, unless you start to see the plant needs something dont add anything, Good organic soil with osmocote Time release fert should be good for atleast the the first 4 weeks, its what I have been using
I would transplant ASAP tonight if possible, the longer they sit in that toxic soil the more harm is going to come of them. Just try Peat moss for your next grow then. For me its been great for transplanting my plants, only issue is sometimes the pot wont decompose fast enough so I tug it up a little and if I see the whole thing will come out I will just remove pot by ripping it, very easy, and then set the plant and soil back into the transplant soil.
Like I said before, I don't think you need to add nutes so early, I would wait a few more weeks before adding nutes, but maybe someone else will have a different opinion on this.
Some good organic soil, maybe throw a little time release caps in it OSMOCOTES have been working great for me. I wouldn't start in any soil that is chemical based like MG. and just try and keep water at 6.5 what has been working for me.
Np, you have a large enough grow room, to try a few different things, why not try a few different setups of soils and see what works best for you
. i have a 250watt metal halide and i just started ph balanced water at 6.0 and the next watering they get will be at 1/2 nutes.. right now they have been in foxfarm ocean forest soil for 2 weeks, i was told the soil will be enough food for 2-3 weeks.. so one more week and i begin nutes. but i dunno if the plants are sad, mad, or happy. i been using home filtered water for now. and will begin the r/o ph balanced 1/2 nutes water in a week. my temps stay from 70-78 and my humidity 45-60. ok thanks everyone for looking
...should be fine.
