HiYa again..
Personally, I would NOT be giving any nutes at this stage..You really need to get rid of those Peat pots, since they leech water away from the seedlings...Remember..Hands off is the best policy, especially for young seedlings..JMHO!
I Made the same error using peat pots..never again!
Say whaa? Peat pots are bad? Dangit. I got a small 'starter pack' here in Australia to try and mine seem to be doing okay (maybe different?), though my light was pretty poor. Simple desklamp for germing. The pots seem okay for a few weeks from seed. I'll give them another shot when I get my lights/timers set up but I personally haven't had a problem with the peat pots yet. Maybe I'll change my mind when I get my lights setup, or maybe they are a different type of peat pot? (you being in the US and me being in Australia).
Oh, and I'll be sitting in on this grow cause my first non-bagseed strain will be White Widow so I wanna see how they grow.
