Over watering or something else?

Ive never had this problem before. im using a sheaper coco peat instead of coco perlite mix from a hydro shop. the good stuff is8 hours drive away.
I watered once every 4 days as the coco doesnt dry out quickly. The frst one is healthy OG13 in the smae mix as the other holy grail kush which is very uhealthy. ive been treating both the same.

The holy grail started off as a runt while the og 13 stateed in full swing.

Both thoes girls are hungry. Feed em

I will up the nutes but the coco is too wet still and stays wet for days. the main probelem is th hgk cupping and getting crispy looking sickly. never had this problem before.

Do you have a fan going? If you dont circulate the air, your medium will stay wet longer.

Its the peat. Coco is ment to be watered every day.

Make your life simpler and grow in a soil mixture.

All the "...ponics" methods work great if you are on top of your game. But fuck up one time, just once and they are toast.

Otherwise nothing beats a soil based grow. Very forgiving.
