Looks like a ph issue. Slurry test will tell. Also let those planters dry an inch down between watering

yellow spots on upper leaves, towards the end of flowering, I grow in a Coco ,flowering 8/10This is my second attempt at cocus
I work with Plagron nutrient solutions(Coco Nutrient)
I follow the table, there were no problems on my first try.. should i stop nutrients? I always mix the water in a bucket, so I can't spoil it either, because most of the plants are healthy, ph 5.5 is always between 5-7!Leaves. Edges burnt

Tips turning into yellowWe started feeding the plants 10 days ago. Some leave tips started to turn yellow, we think is due nutrient burn. We decided to water them without ferts for once, to flush out the excess nutrients. Is it a good approach? Could it be from light stress? (See pic for reference)2 years ago

Leaf identifyThis is my test plant.
Please help identify leaf. This is nute burn? Top of the plant look just fine. Should i worry?
Before this happen I feed her 570ppm and try supercropping on main stem (twisted). She fine with 660ppm in the past so I confuse what is the problem.
Thank you.Leaves. Edges burnt

Yellowing/purpling leaf tips outdoorsIm experiencing yellowing/purpling on upper canopy leaftips of my outdoor organic cannabis plant in week 2 flower. I'm feeding via compost+dry amendments so over/underfeeding is unlikely. What might be the cause? nutrient lockout? Relatively low temperature (57-75F)? pests?Week 10
