HELP. 4 weeks what is happwning

One thing at week 5-6 feedings do t add calmeg she won’t need it that far in I’m in hydro and I cut the cal meg out on my week 6 Rez change. @PurpNGold74 I think he’s on the food water water schedule and if he is every 3 week is a flush week depending on what his run off is

Ive had a lady actually start showing signs that early. (Around 5 if im not mistaken) but i chalked that up to my horrible pH’n practices at the beginning
