Sorry in advance for writing a damn book, Im a little baked and just started rambling on.

So Ive got a plant thats yellowing out. A Blueberry Headband Auto started from seed in a Rapid Rooter plug then dropped into a Waterfarm setup. Its about 4 weeks into flowering now (give or take). Everything looked decent until a week or so ago. The leafs are turning pale yellow and ending up getting dry splotches and then easily being plucked off (not falling off on their own totally). PH is kept between 5.7 and 6.1. Using the Elite line of nutrients at 1/4 strength (until recently when I upped that when I was thinking it was a nitrogen def.), plus I drop in small amounts of Mammoth P, Hydroguard, Silica Blast, and plus some CalMag recently when I upped the nute doses. PPM sits around 300-350, inlcluding water that is 100+ on its own. Doesnt sound like much but its a small Auto plant, would only stand 2 feet talk max and not very bushy. Temps are fairly high, but nothing I can do about it, Ive done what I can. With lights on and fans running during the day it gets to 81f with the tent open and closet door open. With both doors closed itll get close to 90. Humidity is in the mid to high 40s I believe (off the top of my head). Light is a 400w HPS/MH Dimmable with cooled hood, right now its set to 250w (due to heat) and its about a foot and a half away from the tops. Dropping your hand in there, you dont feel any heat after getting 5-6 inches away from the hood glass.

At first I thought maybe it was light stress/bleaching as the light was closer, so raised it, didnt help. Then I thought probably Nitrogen deficient, so I dropped a couple extra ML each of the Elite part A and B in, didnt seem to affect it.

I also had a Green Love Potion plant in soil that also had the same issues (that plant had all kinds of problems from seed to harvest, so didnt think much of it), that plant ended up with all the leafs either fallen off or dried up straight to the bud line. It went 10 weeks in flower and still never hit that last growth wave where the buds fatten up. The buds stayed thin, small, and pretty airy.

Only other thing worth mentioning is that the Love Potion developed a spider mite problem. I caught it pretty early on, and the Blue Headband was still in early veg then, and I managed to crush it. Used this stuff called Green Cleaner, on both plants. Didnt seem to have any immediate negative effects, and it was over a month ago now.

Ive tried more nutes, less nutes, higher PH, lower PH, tried raising the light, lowering it, none of it seemed to help.Any help I can get on Identifying what the issue is and what I can do to fix it, it would be really appreciated. I love blueberry strains, and since I started growing again this is only the second one Ive grown, the first one ended up being a hermie and got the ax.

Also, I have a Girl Scout Cookie (Blimburn) baby seedling growing in the same tent (waterfarm), It looks like its leafs are getting a little yellow. The seed leafs have gone brownish and dried out. Related?

I don't think feeding it so little for so long has helped. But check your roots. Make sure the air pump and water pump are working right.
What ever you do at this point it isn't going to repair the damage done.

Don't be afraid to use the Elite Nutrients line at their recommended ml/gal ratios. I switched to them not too long ago and underfed because the low ml/gal ratio seemed too low, like it was a concentrate... Not the case. I'm pleased with their products, I won't go back to any of the previous brands I had used, as long as I'm buying pre-mixed/bottled nutrients. They work best for me in the 6.1-6.4 Ph range. I haven't experimented with mixing them with many other brands, so I can't say how well they work in a solution with others.

I can't say that this will fix your problem, but I hope it helps. I just haven't seen anyone on here mention Elite since I made an account, so your post caught my attention. Hope the ladies get better!

Elite seems to work amazing during Veg, but I dont like it for flower. Dunno why, but every plant Ive grow out using Elite has gone fantastic during veg then gets like this during flower. It goes yellow/brown, buds dry out/burn, plant just looks shit using elite during flower, no matter how well I keep track of the specifics and how much I use.

Ive had this problem on the last 3 plants, then the Girl Scout Cookie that was a seedling in the OP, I used Elite for veg, then switched to a simple 1 part flower nute for flower (plus used the Resin part of Elite), and it turned out amazing. It mighthave been the best pot Ive grown.

So idk what to think about Elite. Id use it for veg personally, and switch to something else for flower. My next grow is gonna be in soil with organic nutes so I wont be using it this go around.

I am having a similar issue with my seedlings. Its my first grow, and the seedlings are turning yellow on the first true leaves, and one has developed a big brown blotch on it and they are growing very slowly, I didnt have time to run into town and buy fertalizer with nitrogen so I used 1 cup of urine and 10 cups of water, tonight, the brown spot is still there, and the leaves are still yellow, but there is almost a cut off line where green might be returning to the leaves. Any help is appreciated!

start your own thread and I'll take a look.. the yellow and damaged leave will die off.. they won't green back up
