Just looking at the seedlings I can see overwatering. And likely if you keep spraying them, you'll develop mold on the leaves. Too much care, not enough patience.

The purple stems don't bother me nearly as much as your using Sweet on seedlings. Your plants are too young for any nutrients and additives, including Sweet. I never even use a molasses product (actually I use molasses) till plants are at least a month old. Sweet, Carbo-Load, CalMag and plenty of other "necessary ammendments" are all molasses or synthetic molasses products. (sugar beet or sugar cane derived)

Once you transplant them into larger containers, (in about two weeks) moisture regulation get's easier.

The purple can be from cold temperatures, PO4 defecient, or it could be from a strain that purples. Do not try to chemically correct this, as it will likely cause more problems than you are solving.

Relax....:jointsmile:

Come to think of it...are we now talking about your ladies or your seedlings...?
