I've got some in the a+b flower feed but i'l try add more,and she's sensitive on nutes tbh every plant I do seems sensitive on the nutes I have never exceeded 800 ppm I wouldn't mind knowing how people get the ppm so high I got a little nuteburn last week after ppm raised to 900, I pull 6-8 oz too
Different nutrients run different ppm's. The more organic the nutrients contain the higher the ppm because it different forms and often arent as fast acting so plants dont absorb them all at once like synthetic salts do.
All depends on what nutrients you are using so you cant really answer that question without considering what your using for ferts.
Hydroponic nutrient solutions you always run lower opposed to soil mixes which fan be run very hot (high ppm)
800 does seem very low for bloom thought you should def be up in the 1200 range eithout issues. Make sure the ppm you are giving them is in correct ratio. Meaning a majority of the ppm come from your bases not additives.
That could be a few different issues. It kind of looks like potassium but it also looks like it could be magnesium or even a Ph problem.
Need to know more about what nutrientd you are using the ph and additives would help alot.
The better question would be if you are giving it the correct Ph and good nutrients why is this problem happening would be better way in solving the issue. Those plants arent very big either so maybe the 800 ppm is good range it just isnt absorbing what you are giving it because you have an issue at the roots. Hope this helps
