hey dad,
sorry for your loss.
I went through something like what your girls are doing.... the leaves turn a lighter green almost a faint yellow hew.... and stopped growing. if you search in the forum, it talks about "underwatering early vegetation and low nutes".
when you grow in a box with a lot of circulation, you dry out the area. In turn smaller plants lose a lot of moisture. Next time you repot, check the root levels. Long roots means she's digging to find more water.... But then again, i'm just one man trying to grow some pot... everyone experiences different things, so many girls so little time....when in doubt, just relax, let her do her thing... she's a weed, she know better. keep it up!
Post pics!
from this to this in 2 days after a good flush......
(mine are in solo cups, so that's might have been my problem.) ........................
but she came around....
