ill be practicing on bag seed before i use any of teh seeds i purchased
That would be a wise move.
And another confirmation, that plant is and has been dead. No CPR for it.
Seedlings are very fragile. IMO it is the most important part of the process and the most worrisome for me. Mature plants can handle draught, over watering, nute burn, and all sorts of shit. But seedlings can be killed very easily.
Keep the lights low, no clear cups, and keep it moist, but not soaked. Wait till it has a couple nodes before thinking of any nutes. And then be very very stingy.
Once you get a little time under your belt, you will know what you can and cant do.
Sacrifice the bagseeds for your learning.
