critical bagseed - "Sapir"

Seedling is in a 5 gallon spacebucket, single 8w bulb currently (about 5k lux) seedling was born with half its first leaves burned out, so only half made it ok It had a very slow start, but now it started taking off, so I start the diary V1 watered rainwater V3 Switched the 8w 6500k bulb with a 23w blue led light, added 2 more spacers V5 Plant seems to be dying. I transplanted to a bigger pot hoping that was the issue. My other guess would be the switch from 8w 6500k bulb to 23w blue led light, light might have been too strong. Switching back to the 8w bulb V6 leaves are perking back up :) probably roots were too big for the pot.
