Hi guys! This is my first grow, I’m using hydroponics and I’m starting to see a white substane on all my stems. It’s also appearing on some of my hydroton, but I don’t see anything on my leaves. Is this powdery mildew? What should I do? Also I’m starting to see a little bit of discoloring in some of my leaves. My PH is reading at 6.2 right now as well.

I don’t think it’s powdery mildew. It usually starts on the leaves. And I don’t see any white powder on your leaves.

They grow up so fast :cry:

She's hardening is all lol(there are some adventitious roots looking like they wanna go hang out with their cousins though.

No worries in my opinion! That leaf may suggest a Cal Mag issue but it's too faint for me to really tell.

Thank you so much for the reply! I was getting worried about my babies lol So do you suggest me flushing the plants with ph’d water to fix the calcium and magnesium issue? I have another plant whose ph is reading 7.4 right now and I know that’s high. I don’t think I allowed the water to sit long enough when I mixed in the nutrients on my last feed before testing the ph.
