Red stem might be that since you going into flowering , there is insufficient P K . Not to say that is not there , just hasn't been absorbed ( plant is transitioning ) or you should of gone with 910ppm. I would get the tip curl when I would use pots and the soil got too dry and then fed them suddenly . I call it the almost overwaterd almost overfed w/ the wrong nute type of look.

maybejust drop the ph a bit....food will be better availeble to the plants....5.8 ish..might i also suggest lowering the dose a bit....i see starting signs of the claw...that means overfertillisation...and can result in hanging leaves
