Hi all, here's the problem:
Strange waviness to leaves with some brown or necrotic looking spots starting to develop. The spots don't appear to prefer a location on the leaf, there are little brown spots here and there. Older leaves only.
Grow details:
Indoor, 2 1/2 weeks from seed
3x3x7 cabinet
General Hydroponics Waterfarm (recirculating DWC) 2 Gallon with Hydroton
Using the GH Nutrient schedule for seedlings (1/2 strength) with Tap Water that has an average of 160PPM before nutrients are added.
Also using some roots excelurator, and a bacterial innoculent at 3/4 recommended amounts.
Mars Hydro Mars II 700W LED, currently at 20" from canopy
Average Temps: 70F Night, 74F Day (Very consistent)
Average RH: 60 Night, 45-50 Day (Pretty consistent)
Plant variety: Dinafem Critical+ feminized
Recirc pump runs during lights on, 20/4 currently. I've not noticed traditional overwatering symptoms, so I've kept the pump running constantly, except at lights out.
I pH to 5.5-6 using the drops, though I see a rise in pH after a couple days(thus the use of the bennies) I change the water weekly, that's two water changes so far, and I top off with pH'd water when the level gets an inch below the fill line. I try to keep water temps about the same, though they may be a degree or two cooler than the reservoir, which I just measured at about 70F.
I've noticed small droplets of water getting onto the leaves, from the recirc water. Not sure if that could be it, or maybe I need the Hard Water micro, or my light is slightly too close.
Anyone have any ideas?

Plant is otherwise healthy and appears to be growing well.
