HELP!! Nute burn?

I don’t know what’s going on. My waters ph’d and I’m using Remo nutrients (just finished week 7), terpinator, and mammoth P, and have good airflo. I thought it was a phosphorus deficiency, but it seemed to get worse, after adding mammoth P. I’m going to flush, I guess, to see if it helps at all. Any suggestion would be appreciated. I hope I can save these, and I’d sure hate to harvest early. Thanks,

What is the pH and PPM of the soil runoff? Also, what grow light are you using and how far away is it from the top of the plants?

@Mr. Grow It I just checked my runoff ph, and it’s 6.4. I dont have a ppm meter at the moment. Can you recommend a good one, that maybe won’t break the bank? I was looking at the blue lab truncheon wand. I have an sf-4000, and it’s spaced at about 17 inches In a 4x4 tent. I’m wondering if it could be under watering. I have four 5 gallon cloth pots, and usually feed, and water 1 1/2 gallons for all 4 when feeding. It just took me over 3 gallons just to get a run off. The problem seems to be getting worse also.

@bukesta1er Here is a TDS tester that I used to use: https://amzn.to/3DquhiU and here is one I use now: https://amzn.to/3qJjrkS Potential light burn? https://www.mrgrowit.com/post/light-burn-light-stress-in-cannabis-plants

@Mr. Grow It Thank you. I’ll raise my light to 24 inches. I even dimmed it to 80%. I’ve never experienced this, it’s crazy. I’ll give an update. Thanks again. I’ve learned a lot from your videos!

Hi, so you are on Week 8 Day 1 of flower with 2 or 3 weeks to go? The lower leaves look nice and healthy and since you are close to the end I don't think you have to worry too much about it.

The damaged leaves look like it might be nutrient burn or light burn, or maybe a bit of both.

Most will flush about two weeks before harvest so I would wait until then to do the flush. For now I would raise the light and just water with plain PH'd water every other feeding.

What week are you expecting her to be ready for harvest?

@Cap Stone sorry, I replied in the wrong spot earlier..

Yes, day 1 of week 8. 3 plants are looking like 10-11 weeks, but on the last one, the pistils are still white, and haven’t really started changing colors yet, so I’m guessing that one will go a little longer. The trichomes still look pretty clear on all of them. The 2 front plants are “cement shoes”, and the 2 back ones are “stycles”. Thank you so much for your recommendations. I was getting pretty worried. I’ll raise the light now, and alternate water in between feedings. This is my 6th grow, and had never experienced this.
