I agree. Looks like nitrogen toxicity. The leaves are a really dark green. What do your roots look like? What are your reservoir temps?

What was your ppm last few days did it raise or fall?
You do know when the top of the plant is burning you are feeding too much?

I try not to ever let the P PMs go above 1250 I understand I might’ve got it a bit hot in the past, but typically never go above that mark I have burnt plants in the past accidentally, but I never have had it where the plant loses all its vigor to the point that it can’t support itself like this

Soo you have no interest in ppm you just aim it to be 1250 interesting way to grow. Not all strains like same nutes i had plants that wanted 750 and some that wanted 1900.

Why do you say it lost it vigor? She looks okej.little thin but that can be from light being too far

Proper way to grow in dwc would be to watch your ppm daily and look if it goes lower or higher that way plant will tell you if she wants more or less

I run masterblend its same as jacks and on 300w i need to give it more magnesium. I am not home right now but if lower leafs are burning brown in the veins could be that( google hoe it looks)

I have been running Jacks for a few years now without any real issues, but it has been in peat soilless. The only minor issue I had this year was at full strength (3.6-2.4-1) my tomatoes were getting too much N and clawing up. The dozen or so other crops did fine with the standard feed, if you grow enough plants you're eventually gonna get some fussy ones. The great thing about three part nutes is you can make some adjustments and hopefully correct minor issues. I wound up having to make a sperate solution for those needy tomatoes at 2.75-1.5-0.0.

Assuming you usually have your pH in the sweet spot 5.8-6.2 and roots are clean, you may just have a fussy plant that is a low feeder.
So, if you ran (2.75-1.5-0) you would be reducing N and also the Ca+ Mg+ cations that are antagonistic with Potassium.
You're well into flower so you may not see much change in foliage, but it could slow down the further deterioration of leaves.

Here is the profile of 2.75-1.5-0

My personal opinion is chart is just for the ballpark.soo you dont kill it day one.after that just try to have a stable ppm, no dropping no raising.she usually will get hungry during stretch then after it drop and at the end of grow she will not want much.
If ppm raises give it water and less ppm than day before. If ppm drops give it nutes more ppm than day before


I used the recomended recepie until flower then plant started showing lack of mg soo i had to break the recepie and give her 1.2 or 1.5x more mg
