Hey Africut,
I'm responding to a post that you left on a different thread. Before I got all crazy changing and/or adding things, I would first verify my soil pH. The runoff method of calculating your soil pH, if done correctly, can give you a general feel for your soils pH. But, if done incorrectly, can give you some pretty wild results. I do not trust this method, and prefer to measure the soil pH directly with a soil pH probe. If your soil pH is as high as your test suggests, I doubt your plants would be doing as well as they are. I appears that there is a problem, but in order to properly diagnose and fix the problem, you have to know where you are. And soil pH is a very important piece to the puzzle. Just my 2 cents. Good Luck

*from LHT* >> Africut- (I'll send this over to your thread as well)....ditto to what Oldster said about pH measurements... have a look at this too! https://www.autoflower.org/f90/another-quickie-reference-run-off-testing-ph-estimation-41733.html .... looks like Ca defc. to me too, though the larger necrotic patches are a less common symptom,... the yellowing right along the veins is spot on for it! Soon, you might see tiny spotting appear....I see a lot of curling along the teeth too, several plants,...first guess is a combo of heat/RH/T/breeze strength issues might be messing with the whole transpiration and nute' transport machinery, which in turn can cause or exacerbate defc. issues as well,... though some defc.'s can cause this as well, but don't really see other signs, so,... get us some environmental data too please!
