Nutrient Burn or Deficiency?

1000% Phosphorous burn.
My nutes are mg bloom boost with a NPK of 1-3-1 and I was feeding full strength I'm pretty sure, if not more. I just gave them plain water yesterday. Should I just stick to plain water my next watering also, then go to 1/2 strength nutes after that?

This makes sense with me as my flower nutes are HIGH P. Any relationship by chance between Phosphorus burn and lack of other entities (I use RO and have not added additional Ca or Mg)
Google "nutrient antagonism charts" or "mulders chart". Good reference material because it is too hard to remember what all gets impacted by too much of something.

I watered and inspected all pretty well last night...still have some of the same phosphorus problem going on but it was less prevalent...so I stayed the course with my nutes...while I think I am going to mix in some Ca/Mg my next watering. The "plan" has me going to straight water after week 5... so only 3 or 4 more waterings with the nutes anyhow.

Keep me updated, we got the same problem on the same grow schedule. I went to plain water to see how it goes. Watered them monday and the problem seems to be slowing but not completely sure. I'll probably need to water again tmr (every third day), so I need to figure out if I should go back to nutes or not fast :???:

Will do. The other reason I felt confident it staying the course is that the leaves that are having problems or dying seem rather inconsequential and the plant overall seems happy. So yeah, bottom line is I am going to push them a bit and see where it lands me...I can always adjust the sail if the wind changes.

Here are a bunch of pictures of my plants I took today. Its been 23 days since 12/12, they have been growing for 76 days overall. I figured some pictures of the entire plants and a couple more leaves/tips might help me get some more advice.

I used to love mg for mother plants, I think the reason people say it sucks is because of the time released nutes that can't be flushed or whatever, and if you try to flush in thier time released soils you just end up over watering and over feeding the plant, since nutes are released with watering.. but it works well so the haters of mg are wrong. I think you got an nute burn going on, but not sure. The green leaves with the tiny burnt tips looks OK though

plain water or nutes? thoughts?
I'll tell ya again, go get some MG Cactus nutes, it's 2-7-7....perfect ratio for you, start by mixing 15 drops per gallon of water...get yourself some Epsom Salts, this is the Mag in Cal-Mag add a 1/2 tablespoon to your gallon of nutes, it's all natural stuff :bigjoint: and if you're in a city, use your tap water, just let it set in a milk jug or another open container for at least 6 hours, to evaporate all the chlorine out, your tap water has other chelated minerals too besides calcium, it has iron, copper, magnesium, and some more shit I don't know the names of :hump: :clap: :clap:
but it's gooooood stuff...check the PH first by itself and then again with your nutes to see the fluctuation and if PH is too high, use all natural apple cider vinegar (the dark stuff) to bring it down...1/2 teaspoon is .5 so adjust accordingly, and if you have any microbes in your soil they will regard it as food and it will be gone quick...I doubt it will be to low, but if it is, you can use the same 1/2 teaspoon of lime juice to raise PH levels .5...peace and good luck

So, which way did you go? As mentioned I nuted regularly on Tues again and things seemingly continue to be better or about the same. Still losing some fan leaves and a few inconsequential others, but everyone is still happy. I have to leave things for a week as I have to travel. My wife, pretty much a master gardener, is intimidated by my room. ;)...but it will be in her hands. As my waterings have been every 4 days lately so I hope to drench everything before I leave on Monday...with hopes that they don't realize I am gone...they might miss my soothing voice.

I just watered them with plain water for the second time, every 4 days. My leaves seem to have stopped dying and the buds are coming in nice. I figure I'll know within a day or two if I need to go back on a low dosage of nutes the next watering. I'm pretty sure I fed my plants wayyyyy to many nutes and I had to flush it all out. I'm still on a half gal of water every 4 days.

Needs food, light green equals nitrogen deficiency.

Singed leaf tips are from potassium deficiency....

Plant is trying to grow, feed
