Do not over water them. Water, wait for soil to be dry then water again. You can go by weight as well. Over watering is a huge beginner mistake. Are you feeding them any nutrients? Seedlings do not need nutrients till the sugar leaves have gone. Soil my be too hot for seedlings as well.
No nutrients being used yet. Watering about every 3rd day depending on soil dryness.
The room 15’x15’ has a space heater to keep temp mid 70s to 80. The grow area is
shielded by mirrors on both side and reflective foil to the rear about 4’x4’ area. Ceiling
fan on medium for air flow.
most miracle grow has time released nutrients in it…as @QtPatooty states
‘‘miracle no’’ some call it.
use a starting mix such as light warrior by fox farms or jiffy seed starting mix…very light soils needed for seedlings,then after 3-4 node’‘sets of true leafs’’ then you can start adding more nutrients…
i would use the miracle gro for flowers or something like that. @the.attache
You’ve got a few problems going on here. First, you used Miracle Grow soil which has slow release nutrients in it, so every time you water you’re burning the plants with nutrients.
Second, there isn’t enough light. Move the lights closer, about six inches from the plants, but make sure they don’t burn. Those mirrors aren’t helping, they actually don’t reflect very much light, and your containers are not light proof. Roots don’t like light, so cover the containers with tape or paint them black. Better yet, I recommend you transplant in to some appropriate soil that doesn’t contain nutrients. Any seed starter soil will do.
I’m not sure you can save these plants, your grow space really isn’t set up for growing plants well. Lighting is very important and i’m not sure your lights are adequate for growing cannabis. @dbrn32 wil these lights work?
