I'd get the pH down some more if I were you... should be between 6.0 and 6.5 with 6.2 being the sweet spot... If you've got a lockout or your pH is too high, no matter how much calmag you give to a plant, it won't be able to get at it so you might consider doing a flush (3x the pot volume of pH'd water through each)... let it dry out and then when dry, you can reintroduce your nutes at 1/2 strength for the first feeding cutting way back on any nute that has a heavy nitrogen content.
Good luck...

Hey Growmie,
You have a nutrient lockout, this happens when your ph is off, and your soil ph is a bit high at 7, I wouldn't let it go past 6.5, even though you gave it cal-mag it's not intaking it due to this.

Maybe PH Lockout?Hello everyone, can you maybe help me? My Black Cherry Punch has some kind of problem. I suspect it’s a nutrient lockout caused by the pH value. I flushed it two days ago, and the drain had a PPM of 1000 and a pH of 7. The plants are at the beginning of the 2nd week of flowering.

This margin curl appears to have spread from one plant to 2 of the other 3. So I assumed not pH, not lockout, not nutrient based. Roots all great. I've culled the 3 and there is 1 survivor doing well but what was this? In the diary I mention using Temprid FX, Neem, Spinosad.

What may caused the issuesChecked the runoff and confirmed 6.2PH and 130 ppm on water.
checked on my Tank and same was happening.
so gave a 603 ppm solution of cal/mag. Grow A+B perfect pH connoisseur, H2O2 at 5.8 pH.
Will await for results.
i think at week 3 theyre supposed to eat at least 600 ppm?

Advise to flush or feed in VegDoes this is look like a nute burn, deficiency, or ph problem? The two plants that are growing a tad taller have had yellowing tips some curling downward. Don’t want to overreact and cause it to worsen, they’re looking healthy otherwise. Any advise whether to flush or feed?

Leaf-tips going droopy modeAfter my second to last watering the tips of all of the leaves started to droop a bit. I though it was connected to the night-cycle of my light, but it continues to worsen every day. However I only watered after the soil was dry too the touch? Is it really overwatering or else?
