Alien Berries (AVTxStrawberry nuggets)

Looks like light and heat stress on one of the pictures. Not sure what the issue is in the others. I would raise your light a little and see how she responds as the third pic does show heat stress and I am assuming light burn on the leaves but could be magnesium deficiency. Epson salts will sort that. Keep an eye on your PH as this will cause CalMag deficiency. Hope this helps, good luck and happy growing

Springtail and they are good for your soil

The photo is too small to tell. It could be a juvenile stage.

Olá amigo, tudo bem? Também já tive esses bichos, logo no início do cultivo. Até pensei que vieram com a terra porque eliminei e nunca mais vi bichos desses.
