NEED HELP - Older leaves dying...

for future reference on difs

@A-Train, there is indeed a stand alone cal and mag in the cutting edge line up. For future reference.

What is the feeding ppm here? Have any silicon in there to boost the cal uptake?
Is the spreading just in big fan leaves? Had a similar problem. I treated with more food.
Like the plant is using the nutes there to build a scaffolding but doesn't have enough to build materials to fill in the spaces, so the cells collapse. But the plant just keeps building and pulling resources it has available. Its eating itself. That's how I treated it anyway. Things turned around.

Someone somewhere on site had posted an awesome molecule flow chart. Like
Little globes of cal and mg and n p k and how their all inter connected.
 
you guys are amazing :) thanks for the attention !

Next watering I'll feed them with AN Cal-Mag. Is 1ml/l ok ?
 
Do you have a pH pen? Where do you get your water? I think I would flush with some ph'd water then I would go with 500-600ppms let her come back. But with out know how many ppms your feeding them and what the pH is its hard to know if its lock out from pH swing or you are truly deficient in something. My bet would be pH cause An works pretty well with photos. I have never have a cal/mag issue with photo's, auto yes. Most the time its my water or medium that's messing with my ph, causing lockouts.

Yes, I have a Ph pen :) I usually use bottled water with a ph ~6.6 but with the nutes the ph goes a bit low I think...
