Hey there Elmer ! I'll tell you what : you've been watering these just fine man, in fact looks like perfect watering, thing is those burnt tips are due to over fertilisation ... put simply those tiny seedlings weren't able to absorb the grow + bloom + voodoo... most likely it's an excess of N, perhaps from the voodoo or an N build up from the combination of bloom , voodoo and whatever N is in the micro... sad thing is, at that age if that happens usually the plant gets stunted forever, and honestly might as well restart with fresh seeds and find that sweet spot with your line up. Otherwise you can transplant them as is and try to muscle through... hey at least it's not a watering issue, you can tell because the leafs are not puffy, they are praying a bit, and the plant doesnt show any signs of overwatering-related stress. Hope this helps ! 🚀
