hey there stardawg #1 has some root problems, cut out the nutrients and only use enzymes (like cannazym or something similar) for the next few waterings. for the speedy boom 1&2 the soil is too "hot" has too many nutrients in it so the leaves are burning. best thing is to take the seedlings out of the soil, flush the soil by watering until runoff then 20% more water, squeeze out the excess water and put the seedlings back. Hope this helps ! 🚀
