So turns out to be overwatering auto pots and soil works well but needs some tricks, first plant needs to be more develop like 4-6wks veg and 1-2wks flower then its good to go on autopots.
My autopot soil humidity stayed 55% for 2 days then Day 3 53%
day 4 50%
Day 5 46%
Day 6 42% still need few more days to drop to at least 35% soil humidity before Ill start watering again, so basically my ladies where drowning, from now on Ill add clay pebbles on top layer of soil to evaporate more maybe even a fan pointing to stems/soil. So my plants turning all green again after now watering them for 5-6days and still 2more days to go
at least its sorted now
Thanks for everyone!
