Please help, what am I doing wrong?

  1. I have 7 plants, in the tub, under a 400w mh, light is about 12" from the plants. They are in small hempy buckets (cups with holes) 3 to 1 perlite to vermiculite, I just gave them their 1st feeding, with 1/4 strength gh floramicro & grow, rapid start and Dutch master gold silica. There are two things I can maybe think of, the temp is a bit too high in there (85ish) and when they germinated, I planted them when the first root was about 1/4" long, I know most people do it as soon as the seed cracks. One of them was almost 1/2", it grew fast in like 4 hours. The 4 on the left are white widow x big bud. The 2 tall ones are white widow x skunk and the tiny one is cotton candy. Sorry it's so long, I just want to give you guys as much info as possible. Thank you so much for any info!

  3. I'd start by putting domes on them.
  4. Ssdi,
    What issues are you talkin about exactly? Seeing as they're seedlings i would not put domes on them. Be sure to water them with water ph'd to 5.8.. I give mine 5.6 because my tap tends to rise and stabilize 2-3 points higher than initial drop. Keep in mind that seedlings don't need any food for the first week or two of initial development.. Also feed them very lightly 200-350 ppms for the first few weeks - stay on the lower end and top off around 400-600 ppms towards the end of veg (many people feed at higher rates, but I like to give them just what they need - keeps things less complicated). Keep that strength for the first few weeks of flowering (different npk rate of course) and gradually work back down in strength - like a bell curve. Also, what are you using for lighting?
    Btw- got a few in hempys myself at the moment so if you need any more advice let me know
  5. I dome my seedlings until they outgrow it.
    To each their own, as long as it works out in the end.
  6. shouldn't feed anything but water for first 2-3 weeks
  7. Yes blaze to each their own my brother .. ImO doming seedlings will increase the chances of mold/root rot.. Doming is only necessary for clones because they lack roots (even clones dont necessarily need to be domed - i dont dome mine) therefore lack the ability to drink and will get their moisture needs through foliar feeding - humidity in the environment.
    Ssdi- I'd pick that light up a bit.. 12" is a little close for a 400w MH on seedlings .. I'd go to about 16-18" and just lower it some if you're getting some stretching..
