Fantasmo Express by Mephisto

Hey there just a thought...I see you have a mag cal in your nute regime. Could you possibly need a root drench so that they can actually take up the products you're giving them? Sometimes all the needed stuff is there but unreachable due to lock out. If its available to you the Bush Doctor Sledgehammer helps to clean up the root area and generally spruce things up, so the plant can actually make use of your products. I hope she turns around for you, Best of luck with the grow.

i think your ph is too low

Mag and Calcium deficiency looks very similar to me when moderate. I would say it is one or the other or both. Up your load just a bit for a week and see how they respond.
