HELP! BEEN MONTHS TRYING TO DIAGNOSE!!

Super dudes, check out this vid. Is it me or is my shit getting worse?!
Dude it's all over the plant, it can't be good. They were still a little heavy so I said fuck em n left them alone. One felt top dry a little so I sprayed it with plain water wit Calmag.
They starting to look like my camouflage pants
This shit crazy. Think I should just flush with plain PH'd water?! I put a gallon in each one time cause I thought I mightve fed them hot nutes but this was in veg.. did it twice, 2-3 days apart.
Or should I just do the normal half gallon when I see them type dry?! Which would probably be tomorrow.

Someone mentioned distilled water, anyone think that maybe my tap water is bad? Tap is RO right?! My PPM isnt
that that crazy high, it think it was like 160-200 or something like that.

Spots on some higher top leaves, not only in the middle. Some of the burnt tips are curlled like a MF

I'm telling you I ain't stopping till I figure this shit out. Too many threads with interesting beginnings but they never explain at the end what it was. We fixing this problem. Y'all wit me or what?!? .

I use the liquid and powder version. You make a paste with the supplied liquid + soil, and sprinkle the powder on top.

You can also use a soil sample + distilled water and test with a digital meter.

How have you been measuring the ph of your runoff and water. By using drops?

Just take it easy with the fertiliser, they're healthy looking plants to me. Bump it up a little, but don't go crazy.

I'd bang heads with @TrippleDip to compare what you're each growing in etc.

Just get a bit of clarification first. Not having used GH myself, i don't personally feel comfortable telling you to bump up the dose. They don't immediately look that way to me.

For right now, I'm a let it dry and feed plain. See how she reacts. Sounds like my only reasonable option.

what is the ppm of your tap water? RO is tap water that has gone through a reverse osmosis purification system

Good luck keep us updated.

For curiosity's sake, next time you water, water until runoff, but also check the ec of the waste if you have a meter. It won't give you a very accurate read, but it might give you an idea.
Test a sample of the top soil too, distilled water would be best. If you have to use tap water for the soil sample, keep in mind the ec/ppm of your tap water. You can do this one today. Make a slurry with the soil sample, leave it to soak for several minutes. Then strain it through something clean, and test the water's ec/ppm.
Test the ph of a top soil sample too, you will need distilled water for this one to test with your digital meter.

Please, don't do anything when you get the numbers, whatever they may be, and post them here.

The plants aren't going anywhere, or gonna die overnight, so just be cool. They have weeks of life still left in them, they are far from dying.
Don't give them anymore calmag or nutrient until after their next watering, and make sure you do those tests. Doing the tests will give an indication of what's going on in your top soil, and what's happening further down too. It'll give everyone here a better idea of what to advise you to do.

Test a few pots, individually.

lmao, read your description then watched the video. Your plant's look great. I'd keep doing what you're doing to them. I always see some burnt tips in flower and will probably never know why.

I also blamed my tap water for these spots once but got nowhere except spending a bunch on distilled water. My tap water has chloramine and comes out anywhere from 150-250ppm. Don't think that's high enough to be a problem, more like 400 or 800+. Haven't used distilled water for a while now and noticed no difference.

Just wanted to post some examples of a bad K def I had and when you might start worrying about it hurting your yeild. Notice the burnt tips. Also note that your plant will be experiencing deficiencies for a week or two before you see them and as long again before they look like this. I also think P deficiencies are not so likely. Despite popular knowledge cannabis doesn't need much Phosphorus to grow.

Here are some recommended n-p-k's I looked up as p2o4 and k2o:
hemp nutritional requirements 60-18-61
mel franks insiders guide 100-100-200
Amer. Horticultural Soc. optimal cannabis growth 220-96-365
I have seen it stated that Cannabis needs only 40ppm of P2O4 at any point in it's life (no source, from user here) and that we're all overfeeding anyways.

This is one of my favourite references for cannabis deficiencies because of the short pts and simple pictures.. https://www.growery.org/2991/Diagnosis
