Severe leave yellowing

Quantum kush
Watering 2 to 3 times a week once soil drys out.
Ph was measured at 6.2
I dont know my ppm
Ecoscraps organic soil
Using seaweed kelp every other week at half dose
Rhizotonic every 3 watering at half dose
Terra vega at half dose every 4 waterings
Growing under 2 ft 4 bulb t5 at 216watts total about 3 inchs from top of plant
Temp is at 82f with lights one
Growing in a 36x18x30 vivosun tent

Severe yellowing of the plant has begun happening and no idea why. Any help to save would be great this is my first grow.

Looks to be starving to death!!!

I am watering them tonight, or so you mean nutrient lock?

Really could use some help here please. This way in the future I can help solve it myself and for others

Eco scrap is crap .

If you got at Home Depot , where I see this stuff at , go get Dr. Earth Veg Garden .
Called “ Home Grown “ on bag.

Transplant them . They are starving for nitrogen , dr. Earth has a more balanced mix of amendments .

So much so ... it will run on water only for weeks. A much more versatile mix than even fox Farm ocean forest.

I'm no pro, but it looks like possible lockout. Definitely lacking nitrogen.
And the wilting looks like possible under watering, but then again it may just be all one problem.
Have you checked the ph of your soil, or run off?
I'd search hard on this one man, they look like they are in rough condition.

I'm willing to try it. So, if I grab that I assume I would need to get the roots free from most of the ecoscraps they are in?
Know any good guides to help me so I dont shock the shit out of them?

I definitely wouldn't break apart the roots in the state they are in...
Just transplanting without breaking up the roots can stress a plant out.

Ph run off was at 6.4.

I just want them to to liiive. Ugh.. so feed them tonight then try to transplant in two or three days I guess...

The ph seems fine.
Like I said man, I'm no expert, but that 100% looks like either a ph imbalance, or a defiency.
My last plant was an outdoor, but it had a very similar problem. (Well it had a bunch of different problem lol. Pests deficiency, ph. Literally everything. Somehow I saved it though and it turned out decent)
But the biggest thing was also nitrogen deficiency. They leafs yellowed from the outside inward, and the tips slightly pointed down and gradually wilted mostly.
The first thing I did was gave it fish fertalizer at full dose. And the very next watering I gave it half dose. And literally in a couple days every leaf was back to a nice vibrant green. (Until the spider mites came back)

It's tough to figure it out when you have symptoms like that. Because there are soo many problems that have those very same symptoms.
And I know very little about ppm also, but I've read that it can mean life or death in some cases. So it's worth looking into

I loudly second the above post about the plant starving for nitrogen. and although i dont know that soil, i suppose it is likely very mild. get some nitrogen rich ferts of your choice

So I just went and did a bit of research for you.
If the yellowing started from the bottom of the plant and worked upwards then its almost garaunteed nitrogen deficiency.

Another possibility, is problems with your root system. Issues with the root system can cause a huge variety of different symptoms. Considering that's where it drinks, eats, and breathes. It could cause symptoms of many deficiencies, and root bound can cause symptoms of improper watering. All sorts of things man.
I cant really tell the size of the pot, but if nothing else solves the problem, it couldn't hurt to try upsizing.
Also, take a smell of your run off next time, If it smells bad it could be very likely root rot.

Sorry for the spam messages haha, just tryna help you out.

No no man I appreciate it really, they are 2 gallon smart pots. I just feed them both with some seaweed kelp extract and terra vega. The pH run off tested at 6.7 so I'm hoping the nutes get them through a few days so I can transplant them into new soil. I didnt wanna wait to water them.

An yes i believe the yellowing started at the bottom and worked up.
Thank you man seriously for helping.

As noted earlier, scrap the Ecoscrap soil. I've used this brand (Ecoscraps) of granular fertilizer on a vegetable garden last year and was not impressed. Also as noted your plants need to eat. Once you transplant give them a few days to adjust before doing too much to them. If the new soil is worth a hoot they'll green up and come around without much effort from you. Good luck.

Not a problem man!
Keep us updated!

You must carefully and steadily adjust all liquid you poured into every plant in soil to 6.5 for best result you're guessing at your pH and I don't think you're measuring it by what you said anyway 6.2 is too low and you're locking out Cal, mag and probably some other things that I haven't time to look up right now, buy a $10 meter or better still for $20 get a PPM and pH meter a cheap meter is better than no meter or you can get paper strips I don't recommend the little liquid drops they're not great and they can be hard for noobs to use, good luck

How would this guy have lockout?

What do you mean 26.5 for beat result?
And I am using a pH pen I got it off amazon for like 12 bucks.

(Thanks for the spell check I went back and edited)

Did you properly calibrate the meter when it arrived? (you must check calibration often on inexpensive meters)

Weed will pretty much grow in a cup of sand given the right amount of water and light. I'm thinking you need to check your light spectrum. I had the same issue and that's what it turned out to be. That is - after exhausting all the stuff you've gone through. Get yourself good middle-of-the-road 3500k LED and go from there.
