I posted about this and over the past week I've been rattling my brain to try and figure out the problem before it was to late. Thanks to those who responded. I hope this helps other people out. It can be pretty stressful during these hard times. Especially when you have never seen this problem before.

The photo is a little misleading. The plant was in a 2x2 tray w/o a dome and humidity was 20%. I put the plant under the dome and took a picture approx. 1 hour later when the humidity reached 51%(before).

After about a day I saw the progress and took the "after" photo. Sorry for the confusion.

Ebb and Flow - Thanks for asking. Seriously. Give my your thoughts. Before I went to my big light there where under a 200w CFL given a flood twice a day, half strength nuts and they looked great. Then I stepped them up to the 600w and went to full strength nuts and flood three times. This is when the issue started.

When under the CFL the light was right on them and rh was according to my digi ther/hyg 30%. I think my hygrometer is off but anyway I can't do anything about that right now. It does change as I foliar spray them it goes up so I know it's working. But when under CFL they looked great and now they look like they do. Hopefully after tomorrow after being under the dome they should look ok. Not great but better. Thanks for the input. Hopefully this information gives you better insight to give me feedback.

Check out my photo. I marked the same internode on both plants to make it easier to compare. Try and make the difference stand out more. Anyway. Once I put my plant under a dome where it was already 51% rh (before) and about 18 hr later it got to the "after" stage and was looking better already. I think so. As far as nuts go, check this out. I use GH Flora series but I use the general purpose/mild mixture at half strength. I did go full strenth for a couple days then backed off but based on the photos I really tend to think it was the humidity. Or maybe humidity played more of the roll. I'm just glad things are looking on the up.

I think what I might do is take some coco and pack the top the net pots and bring the humidity up that way. My seedling are in a mix of hydroton and coco and their humidity is aorund 45%. Plus they are under a 200w CFL. Maybe that has something to do with it.

I agree, maybe you have a strain that is more sensitive to RH. but in the after pics, is that increased yellowing of those lower leaves? at this age u shouldnt have any yellowing whatsoever.

I think it's a nitrogen problem for several reasons. But would you agree that it's on just the larger lower leaves and no new growth. (I just got two good books, Gardening Indoors with Soil and Hydroponics by Patten and Mari J Garden Saver by E.Rosenthal. In there I read about how nitrogen problems start on the older, larger, lower, more mature leaves. By the way, I wish I had bought these books years ago. I wasn't that trusting of mail order/internet.) Anyway. I think the yellowing could be from cutting back on the nuts, when I went to straight watering, went to full strength nuts or just the low rh. Maybe a combination of all the stress. I'm going to get some new pics up tomorrow cause I checked on them a couple of hours before the lgiths went out and they looked much better. I have the dome over them and it has moisture building up in it but my therm/hyg still read rh of 30% which seems off to me. Agree? I don't know a whole lot about rh and it's science.

I'm using the Mild solution mix that is on the bottle. The mixes on the bottle go: Seedlings/Cuttings, General/Mild, Veg, Flowering and maybe another one. But I go with the "mild" mix which is 1 tsp. of micro, gro and bloom but at half strength. Maybe I'll step it up when I change the res. It is a mild solution so I probably don't need to be going at half strength anymore. What I need is a ppm tester. I'm just glad I got help on figuring out the problem. The whole over/under watering thing was driving me nuts cause I've never had that problem before.
