I don't think you need to pinch the buds now, let them grow out, it should slow any growth they have now by focusing it more towards the fruit, but in the summer when you put them in the ground.. pinch all the flowers and buds off.. I didn't think about this myself, but it makes sense, and I think I will follow the same suit, and pinch off all the buds and flowers and just leave the fruit that are already on there
but I have mine in 1 gallon pots, I would do 1/2 gallon pots if you have the room, or if you can find anything that is 1/2 gallon size, but is taller (which I am not sure where you could really find that) but that would be even better.. I was thinking about next year it would be cool to take 2 5 gallon buckets (not trade sized planting pots, actual 5 gallon buckets,)and cut the bottom out of one and put something in there or basically make it 1 bucket.. but I would only do it 1/2 way or something, so that it would be like 7-8 actual gallons.. unless I can find a 7 gallon bucket that has a footprint of a 5 gallon bucket so I can conserve floor space..
but anyways I got off track sorry, like everyone else said, drop the temp, and you can move the light away a little, but keep the time 16 hours or more or whatever you are doing, but I wouldn't really drop it below 16 personally right now.. and I tried this with a few of mine, but mainly because I was curious and they were bigger than I needed them now, but I plucked all of the really big leaves off of the middle and bottom of the plant, they look pretty "skinny" and skeleton-like now, but they all have new leaves growing right above where the old ones are.. like me, you have plenty of time for them to grow new leaves twice over.. so if you can handle plucking them lol, give it a shot if you like.. but I would stick to only the really big ones, I notice that they tend to hang real low and are just heavy and are not really perky like the "newer" leaves.. got the idea from a thread on here a few weeks ago
good luck... I hope this weather warms up faster than it normally does, I'm hoping that by april the weather is what it is normally like in May, so by late april I can get them all ready to go in
Oh and to add to your question about planting 2 weeks apart, I think that should work, I think I had mine either 2 weeks apart or maybe 3, but most likely 2-2 1/2 but I kept the younger ones in party cups a little longer than I had the "older" ones in, and left them in there for a week or so longer, and they are fine.. so what I am saying is that as far as I can tell, it should be fine.. I would break your plants up by how fast they grow.. because if you put the superhots or the really slow ones first, then plant the annuums or faster growing ones next.. the annuums will catch up to the superhots pretty fast.. so might have to wait a week extra between those 2 or something like that
