CSI humbolt plant problem

I have bunch of plants I put in a mix of happy frog and pro mix and added some nutrients to the soil I used lil bit of everything not sure what cuz it's was awhile ago but they should have all they need unless they are getting to much idk but they droop some and have light green leafs at bottom and some.fan leafs but.im bout to transplant 15 in bigger pots as they are in Solo cups not I got CSI old family purple and med purple urkle and the bigger ones are cherry bomb Gorilla bomb and gorilla glue not sure what issue is some help will be appreciated

Look a little overwatered and maybe bump up nitrogen. Look good though

Nah not to much water I been forgetting to water them acually but I do water like every 3 days

check ph and ec need more a&b imo

Yea pH could be off but I was thinking maybe the soil is to hot maybe but idk they keep dropping and don't know why bout to just flip to flower n get what I get and start fresh next time
