Leaf curl... proper posting
Sorry for not following protocol before.
I've noticed some leaf curl on some of the leaves. I believe these are some of the original leaves from the clone transplant.
Does it look like heat stress? I had used the 'back of the hand test' and the temperature was not that hot at the tops.
The room shares space with bubba kush and cheese. Only the bubba kush (which has significantly wider leaves) has shown this problem.
It's not widespread, only a few leaves, and the others seem happy.
I was going to leave the effected leaves in place until they fell off, should I remove them?

Nope. Not a heat issue. Put the lamp back.

Old leaves are old news. If the new growth is fine, they'll be fine. Might have been something you sprayed or an additive you used during or just after rooting. Was the plant that the clones came from yours? If not, it might have been adjusting to your nutrients, light, schedules, water...
But it does look like they were over-nutrified at some point.

I usually let the plant discard the leaves, and pick them out of the pot. If they are still green, they're still doing something.

You shouldn't need both unless sourse water varies.

I'm unfamiliar with the product, but have you checked online for a feeding schedule? Ya might want to check HERE.

Perhaps the PDF I refered you to would verify the schedule. I'm a soil guy, and water once daily in the summer.
I prefer molasses instead of CalMag now-a-days. But CalMag is ok.
Keep an eye on 'em, verify your schedules and such, and good luck. :thumbsup:
Also, there is a hydro troubleshooting form just below this form, on the page you got this one from. (in case you need it again)

Hey Rusty, notice how the new leaves don't have it? Just the one? Root damage? I am soil guy too, not much help other than that observation

Thanks for all your help.
This quote got me through the worry about the plants.
"Old leaves are old news."
I took a step back and let the plants do their thing and now they are doing GREAT.
The 'old leaves' are still there, they seem brittle and dry but they haven't dropped, I'll let the plants decide when they should go.
I'm now about 2 weeks into flowering and everybody looks happy.
Thanks again.
