Need help first batch 11 to 12 weeks old

I got some gmo cookies not sure if they are auto or reg. Know there feminized. There about 12 weeks old and no bud yet. Started doing 12/12 on lights bout a week ago. I got two plants that are dark green and curling up on the leaves, pretty sure they are root rot and over water, but I also got 5 others that have great looking leaves, all feed at the same time and same amount. But they are losing leaves every day at the bottom, big and small leaves. Should I call it done on these plants or keep trying. Specs 1200watt led light, ph of water is 5.9 to 6.8 when added to soil, humidity runs anywhere from 56 to 68 sometimes in the upper 70.

Pics would help

Or we can just guess


I guess........

In my opinion, they look a bit hot (86F), and definitely overwatered (from looks of leaves, and your mention of possible root rot.)

I brought back a GSC from the brink of death. She was a bit touchy, and I was a bit new to gardening, ha. From what I see in those pics, they’re no where near giving up. I learned a lot from my GSC grow. Cannibas is a weed, very resilient.

I would suggest some recharge (for the root rot, or root healing.) Add a bit of molasses between the recharge feeding to keep the microbes multiplying.

Don’t water until starts noticeably drooping, for awhile. Pick up wet/dry and get used to the pot weight, so you can tell by lifting when it’s time to water. Plants do not all eat the same amount at the same time, even the same strain. They are all unique. Go by pot weight and let those roots heal.

As far as flowering goes, my GSC took 2 weeks to show. So give her some time. Not a professional.. just some random thoughts based on what I see in the pics.

Humidity is probably a bit high too. Really shouldn’t ever be above 60 at this stage or you’re risking mold. By mid flower needs to be much lower. If ya bring the temp down a bit (max 75) that will help with the humidity as well.

Seriously doesn’t look that bad - definitely saveable! Best of luck!

Two look reveging to me

too much going on there with not enough info
