Root bound, salt buildup, under fed, flushed, how to proceed?

Well I've vegged much longer than I planned too fighting bugs, going on 16 weeks 3rd week of flower now.

I should have posted sooner but 4 weeks ago leaves started to burn up on the outside , yellowing and developed necrotic spots/burns.
I potted up two girls from 3 gal to 5 gal and added more promix hp w startup nutes in it. -don't recall exactly the name.
good results more healthy growth and fixed the issue. I think.

Potting up isn't so much an option for the rest of the girls.
I most recently flushed w water ph to 7 with the drops, and tested the same coming out the bottom of the pots.
Plants seem healthier 3 days after.
I have been using 1/4 strength nutes - instead of as much as I could force feed as I did previously run.
I'm wondering if they are locked out due to small container and salt buildup
Or are so underfed they are eating up their leaves.
I've been picking off the sickly looking leaves as they develop and the girls are looking pretty naked. Not good.
Im for defoliation but this is too much.

Here's a few shots of my gross looking leaves.
Should I feed, or flush?

I think I should get a soil ph meter for next go. So I don't end up at this state again. Any recommendations on this?
Please help.

Please don't respond all at once!
Lol

Well I'm going w underfed and upped my nutes. Hopefully that's it and I see some improvements in this tailspin of a go I've had.

Look overwatered or overfed to me. Maybe a root issue.
That kind of an issue at this stage of flower is going to hurt yields large.

Yes it is.
I was on the fence of pulling the plug a few weeks ago. Some doing better than others so I was holding out hope they'd recover.
I was thinking same as you and had been going light on feeds and flushed with some improvements. But came to the conclusion they are hungry.

Any advice on how to proceed?
I'm going to ride this one out and chalk it up to a learning experience at best.

You said you used startup nutes. What kind and how much?
Liquid nutes on top of that could be your problem.

When i was using promix i gave liquid nutes every 2nd or 3rd watering and kept that schedule. Just increased nute strength as they grew.

Your call. They should be growing like mad right now, not dropping leaves. Maybe focus on the healthier ones, get em in the middle of the grow under the light, and let the others do as they will.

So you had plants big enough to go from 3 gallon to 5 gallon and you added start up nutrients? That could be part of your problem.

And not knowing the name is part of the other problem. If you don’t know the name you probably don’t know what it does either. Just a guess.

The hp has startup nutes in it.
"Mycorrhizae"
For the first few weeks of growth.

After I potted up and added more of this they improved.
That's why I decided to up feed last water.

Ummm Promix HP is completely inert. It only contains beneficial microorganisms. It is not infused with nutrients. You *have* to provide nutrients, right from the get go.

I'll let you know if I see improvements or not.
I keep having issues w longer veg times. Seems better to just flip em smaller with less time for issues to develop.
Boy this is a disappointing go.

Spec, what's the mycorrhizae?
I was told it's enough to get seedlings going for a few weeks.

Well, right off the bat, you aren't reading the information on the items you're using. If you did, you would know that Promix HP does not provide starter nutrients.

Could you be ignoring information on your other products, compounding your issues?

The information on the packaging is often very important. Read it.

You were lied to. It is a beneficial microorganism. It is not nutrients.

Don't just take the word of someone. The person clearly doesn't know what they are talking about.

The labels on the products are the authoritative source for what the product contains, and often how to use it.

I think your right, doesn't appear to be food.

I have been using 1/4 of recommended everything as last go I tried about 1/2 to 3/4 strength.
Thinking less is more approach.
I'm not just adding stuff willy nilly.

How would you proceed?
Flush or feed?

What kind of liquid nutes? 1/4 strength isnt enough information.

I'll collect the details and report back this evening.

Thanks for your time.

Doubled my nutes to 1/2 recommended strength from 1/4 strength and girls are progressing much better.

Cal/Mag deficiency, get some and they should be fine.
