IS THIS POWDERY MILDEW? HELP A NOOB OUT

Start to get a feel for the weight of the cups. Dont over do it with the misting spray at this point. Water them when those cups feel so light they almost feel like theres nothing in them. Then, when they have some weight to them, you know they dont need watered.

Heres another veg update, still white dots on the leaves cant tell if its premature thc, spider mites, pm, or nothing lol @Cobnobuler

What's up bro. I think for sure your room temp is to high. Shouldn't be up near 80 for indoor. 73 -75 is perfect. And you humidity level should be around 40-45. But if it's working so far don't mess with it. If you see problems starting to occur then start tweaking shit!

Good luck

Also let them dry out a little for root work.. At the beginning you want the roots to work make them strong and go deeper. Those leaves look great. A little droopy. You want them to be like the top of the Y.

If your are running RO water you should make a habit of adding a little cal/mag to it.
