Ph? Nutrient burn?

Hey guys thanks in advance for reading this. I'll post pics at the bottom . Just finished a run and decided to throw a mh bulb into one of my hoods to let a few of my plants catch up to the others before I flip to 12/12. My flower room usually has co2 however because I'm vegging in there I have an open vent until I begin flowering again.
Soooo I first noticed the edges of my leaves slightly curling up. I thought it was too much wind or the jump from 400 mh to 1000 was too much light.(I flower in 6000 watt hps and haven't had this issue). So I raised the light from already 2ft to 3 ft above the cannapy and lowered the fans and a week later it's traveling from just the edges to the tips and inward. Didn't think it was nute burn because it didn't start at the tips and started on the edges curling up and slowly browning (dying) versus bright yellow.
I'll break down my set up real quick to help you guys try to get a better picture .....

-10 gallon smart pots coco botanicare airation blend.
-Mills nutrients ( first run with this)
-Tap water comes out 100ppm
-after I add nutes I ph down to 5.8
-temp is 75 humidity 45
-I feed feed flush
-feeding at about 800ppm
Not sure what else I left out ? My theories are.....
-Ph???? I have been foliar feeding twice a week .. I mixed a spray bottle 2 weeks ago and phd it. Checked it today and it was 7.5! Not sure how bad that could be but it fits the time line when I started having issues.
-nute burn? I've seen someone who's always killing his plants via nute burn and it usually starts at the tip and is bright yellow where mine is brown right away .I've run these much higher ppm last run and right now I'm feeding 8-900 ppm and I'm flushing every 3rd watering
-Light burn??? Lights are 3ft of plant! So no right?
-wind burn?
-air flow ? Usually I have co2 on but right now I only have a single open hole
-humidity??
-neglect ? A few weeks ago I let the coco get pretty dry for a few days
The first pic is the first sign of curled up leaf edges and the following pictures is what follows ...

Is it only happening on the plant closest to the light? Or all the plants? This is hard to diagnose. From the overall picture of your garden most leaves look fine. It is normal for a few leaves to get stress, but if MANY leaves on the same plant age like that then you have a problem. But if it is just a leaf here and there, then it is not huge cause for concern. Does that help?

Its wind burn. Some strains get easier then others

It's all of the plants and mostly the upper leaves but also the lower ones

mo

do you have fans blowing like crazy on them like @Diabolical666 said... Was your light previously lower than in the pics? Could be a combination of heat stress and wind??

I hope your right... About 5 days ago I directed the fans away from the plants and I'm still noticing more leaves slowly being affected... I also already ran this strain in this room with 4 fans on blast and a 24000 btu mini blasting on them and I never saw this. I'm still not ruling it out tho

Ummm yes for the first day it was 8 inches lower but I raised it because I needed to spread the light out

y

Just an idea, if somebody else knows jump in, but could it be humidity being too low for the amount of heat in the room? If the plant can't transpire fast enough don't the leaves sometimes curl up on the edges? I may be way off

so you jumped from a 400, to a 1000 watt, and raised the light. if you're gonna raise the 1000, why not just lower the 400? your r/h could be higher. in veg, i try to get it to 50-60%. do not flush between feeds in coco. a feed, feed, flush is a soil routine. feed every time. are you allowing for run-off? very important in coco. i don't see any mention of temps. did i miss that? looks like you have some canoeing from heat, and maybe a low r/h. i don't like feeding real high in coco. usually 800-900 ppm for a real eater. you don't need to be foliar feeding. are the nutes coco specific? wind burn??? that's a new one for me... ya, you need fresh air, and circulation. a gentle breeze on the plants is all you need, not a hurricane. you don't want your coco drying up either.

yes I am getting run off. Nutes are not coco specific.
Temp is 76 rh is currently 56

New pics .... The second one is a new issue! Wtf

The leaf margins are yellowing. Can you see it in the second picture in the background

You need some more magnesium. As to the leaves starting to "taco" its something not right in your environment. Check air circulation, temperature, humdity and you might be watering a little too often. You might look up Vapor Pressure Deficit

Thanks for the help guys after this mornings watering everything looks slightly better no progression of anything. Nice an perky. Dirty I was comparing my pics to others and it does look mag def. my old nutrients had a calmag I added every feeding and my new nutes are Mills nutrients A and B do you guys think I can add calmag from another line to a line that I'd supposed to be "complete"???? Or is there another way to add mag alone ?

I've never heard of them honestly. I did Google them and checked out there website, however, I couldn't seem to find any guaranteed analysis on the product line. So I don't know anything about them. There are tons of calmag products out there and yes its completely fine to add to or mix match supplements/nutrient lines and a calmag supplement is probably one most often used. Just be careful, IF what you're using looks like its already got enough magnesium in it you might be blocking it out with too much potassium? You have to really look at what you're already using and make one change at a time or you'll never know where you're at.

You said you are not using co2 and that you have open holes in your tent? Do you have inline fans exchanging air or just osilating fans?

Nvm just saw you fixed your problem

i have a question for you ? did you just defoliate before you changed over lights,after defoliate you have to ease into that powerful light imo.

I think 800 ppm (if you are on the 500 scale) is too high for plants in veg. I would also be using at least 200ppm cal mag since your tap water is low ppm. In my opinion plants in veg do not need more than 600 ppm of nutrients. Definitely get some cal mag. Also feed every watering and also try testing the ppm of the runoff. My gut feeling tells me that if you are feeding at 800 ppm the runoff is really high.

You guys are awesome! I fed this morning at 800 before I read this and the runoff ppm came out slightly lower... Does that make sense? So you guys suggest lower ppm what do you guys think is good in veg and then in flower ?
