I was kind of scared to prune in flower but was really considering.
They are from seed
Grown in
happy frog/ just right420 50/50
Temp is kind of high but its hot here now...84t/56h lights on
75/66 lights off
Feeding
earth juice phd at 6.25
Not able to ph media
I even get my humidity down to 47 but the dehu raises my canopy temp to roughly 87 so i cut it off often. Running an indoor ac as well but very hard to keep cool in july
Ok, this is a start. An RH of 47% is too low (in my opinion), and I personally have better (indoor) runs of higher RH. Go to the link in my signature line, The Charts, and find the VPD chart (vapor pressure deficit). That will help you with figuring out where your parameters fall. It's really important to remember that if the plant cannot properly transpire, it's like it's having a heart attack, it cannot circulate water and food through its own tissues.
Right now I'm going to lean towards a possible Fe- (iron deficiency) or S- (sulfur), and I'd like you to try getting the pH of the feed up and start ranging it instead of keeping it pegged tight. For soil it's good to let it range from 6.2-6.8 or so, with occasional forays outside those parameters, both above and below.
Second, get some Epsom salt, dissolve 1/4tsp in a gallon of water, add a drop or three of some sort of liquid dish soap (or, if you have a proper sticker-spreader on hand, use that) and give the plant a good, heavy foliar application of that. If it greens up quickly, which I do not believe it will, then we must suspect Mg is playing a role here. However, Epsom salt's chemical expression is MgSO4, which means it's also going to provide a good bit of sulfur. This rate can also be safely added to your feeding regimen as a root drench.
Third thing is to get something with plant available iron in it. I've literally used a bucket of rusty nails, but that can take a while to get them rusty, so I think in this case you're better off buying something for an iron supplement. Given what products you're using, I'll suggest going with something organic, though for a potted plant I don't know that it makes a huge difference. Start adding that, and keep in mind that these issues you're seeing on the upper leaves may well take a while to resolve.
Now, if the EJ is already providing all these nutrients, then you should just adjust pH and not do anything else. It's not a product line I'm familiar with.
