I need of some help

Take a look and tell me what you think. Outdoor grow, soil, GH trio. First appeared to look like nitrogen deficiency, then this.

I would be looking at micro nutrients like boron, magnesium, etc. -as well as bugs and heat stress and possible root issues.

IF they were my plants I’d give em a good flush of fresh water, remove damaged leaves which will not recover then use The One by TPS as your main nutrient source. Maybe hit them with a dose of root inoculant - I think it would help.

I used to use GH until Big Brother bought them. Now they will hang up on you if you mention cannabis. TPS is cannabis specific and proud of the fact.

You can fix this 👍🏼

This is neither here nor there but simply a personal suggestion:
Don't use plastic containers to grow in unless it's a hydro tub. I think you will find that clay, wooden, fabric or cloth bags are much better for your plant's roots and... without good roots it's an uphill losing battle. Over time I found that even with drainage plastic simply doesn't breath; water tends to stagnate, plants get rootbound and problems proliferate. I'm looking forward to seeing your plant looking chipper and happy. I've seen your work before - you've definitely got this.

Looks like potassium deficiency. Could be caused by bad pH or could be caused by too much calcium. It's very common the calcium is culprit. Specially when salt built up in the medium reaches a high level. Flushing with straight water could only make thing worse, like bu2b said hose plastic tubs don't let much air into the roots and have poor drainage creating an over watering situation and the plant stops nutrient intake.

With coco/ hydro setups it's easier just to change water or flush with high potassium low calcium nutrient solution but soil is a whole different thing. I stopped using soil years ago due to this kind of situations where one lacks control.

I guess you can try not using the micro for a few waterings and use a bit of grow to supplement the nitrogen along with the regular dose of bloom. But soil is weird and mixing hydro nutrients with soil is never a done deal. Unexpected things can happen due to the biological processes of the soil. Calcium is not easily created by soil but weird reaction can cause the postadium to react with something in the soil

Try to get a runoff pH reading just to make sure it's on range but you may gotta pick between not doing anything different and see where it goes, or make a change like eliminate micro from the waterings and stick with it and hope for the best

If you're feeling bold and want to do something radical you could try to force feed potassium by increasing the nutrient solution EC and force nutrients thru osmosis (that's what hydro nutrients do btw) maybe twice or triple the dose of bloom in a single watering event trying to wash off residual calcium in the soil. Gonna require five times the normal amount you water and gotta do it real slow so it permeates all the soil. This is a bold idea and wouldn't recommend if it's your only plant because it could not work and mess up things more.

Try growing in coco, you'll never look back. I rarely chime in with these long explainers but this is an issue I faced before and took me some trail and error to understand and learn to control. It's a very common issue but rarely talked about. Potassium and calcium are antagonist and don't get along. Just wish someone explained his to me when I started growing. Best of luck my friend.

I think THIS is the answer. Thanks for the help

Is this an Auto Grow? The pic almost looks like the plant is flowering. I agree with 9fingerleafs, the pic looks like Potassium Deficiency. Read up in Plant Problem section of this website to check out what to do about it.
