So it looks like I have blown it. Plants look like shit. They were fine until flowering and now they look like hell.

6 vision NL fem autos
Happy frog w 25% added perlite
600w hps
Fox farms trio stuck to provided schedule
Temp 70-78
Rh 50-60
Just added calmag for the first time
Plant in back right was weird pheno that never looked right but I didn't have the heart to chop it

Sorry about the lights. I will take a lamp down there tomorrow and get better pics if you guys need them. Figured most of you are used to having to diagnose with grow light pics.

This happened overnight? Looks like heat, overwatering, overfeeding (salt buildup). But, those things should have come on gradually.

I'm saying salt buildup since you said they were fine until flowering. I would feed water only next time with 100% runoff. After that, half-strength nutes for a week or two.

As dumme said, better pictures.

Unless someone else has ideas, I would flush 100% runoff, then mild nutrients for awhile.

Next grow, monitor your runoff ppms. I struggled through this a couple times and the runoff ppms were key to everything. By early flower I had 2500ppm and that's where the plant started looking like yours. I cut my nutes in half, then increased a little to find a combination of strength and runoff (20%) that keeps me around 1800ppm through flower. Life got *much* better after that.

Your ppms might be different. You don't know unless you hit it again, which isn't bad to do just to know. If it's what I think it is, they'll be fine. Might even produce some dank stuff. One plant I had nearly died. I kept it alive with foliar feeding while I poured hydrated calcium into the soil (thinking I had a ph problem, because the soil ph was down around 4.6-4.8 due to the salts.). That was some good smoke.

So I just watered them yesterday. Should I wait for them to dry out and then flush w/100% runoff or do this ASAP?

That's a predicament. The downside of flushing now is that you'll hold the soil wetter, longer. Soil ph rises as it dries. So, you'd be contributing to part of the problem you're trying to correct (lower ph, longer).

I would let it dry completely, then do 100 percent runoff with water. I'd saturate the soil (no runoff) let it sit a few minutes to soak and equalize to the soil's ph, then pour the rest. (That also gives time for others to comment. I could be wrong in my advice.).

I'm not familiar with Fox Farms nutrients, but I'm not a fan of these boutique "lineups." (The more I see of FF, the less I like it too.). I strongly suggest using this spreadsheet to see what NPK ratio you're actually feeding. If you're raising PK too much too soon, that could be a problem too. See my schedule for sane NPK ratios in early, mid and late flower. You can mix veg and bloom to get a sane ratio. (You may not want to follow my PPMs. Fox Farms might be different. Also, the spreadsheet's PPMs aren't actual. They're just ballpark for substituting and comparing products.).

Wow... This is an awesome feeding schedule. I wish I had found this before I purchased my nutes (which I did in the typical noob fashion (by which brand had the best cartoons on the labels))....

I've used bloom last 2 feedings at 2/3 recommended strength

I don't know the ratios of what your using but I try to stay balanced. You would be wise to look at those sheets and balance it out to a 5-5-5 or 10-10-10. Or somewhere close. 10-9-11, something like that.

PK boosters are not really needed. All that is needed is a well rounded nutes.
I would flush and figure your ratios out. Go with half strength veg and quarter strength bloom. Work up from there.

Am growing two vision auto nls now also and i believe that you are at a point of no return. From where you are i beloeve you have a 3 week recovery followed by maybe 4 weeks solid flower nutes which will take ages to get back to 100% strength....
If it were me id kill and start a fresh grow brother. Look at my plants, they are just getting by... too much soil in my coco... hahaha

Yeah it's gonna take 2-3 weeks to get new seeds, so going to see if I can pull of some type of Xmas miracle before I chop.

So for future reference the consensus is overwatering and imbalanced/over feeding?

I think overfeeding. Perhaps overwatering (if you didn't wait long enough for them to dry) if you were trying to rescue them before posting the picture. If that's the case, I think they'll recover with water-only and then mild nutrients. Someone said to use 10% nutes instead of water only. I would do that.
