Things are moving along as they should. I've been keeping a closer eye on the pH in the trays themselves (as opposed to in the reservoir only) due to some noticeably high pH (>7) in the trays. Doing so seems to have halted any further chlorosis (yellowing of leaves).
Additionally, I've started supplementing with Orca as well to help with controlling algae in the reservoir as well as giving the plants a bit of a boost to root health. We'll see how that goes.
Your best bet is to get beneficial organisms for roots. Someone mentioned hydroguard. I use this and have no algae issues. Having good organisms mean that bad organisms will be out-competed and won't be able to get a foothold.
Clean out your res very well again and start root bennies BEFORE algae sets in!
