Brown Spots between veins?

First post is a reach out to the community for answers to a question, namely a potential disease problem. Sorry not to bring you all photos of healthy plants!

Strain: Nirvana Auto Bubblelicious x 3; Auto Seeds Auto#1 x 1

Lighting: 240W Blackstar-UV & 4 X 22W Daylight CFLs for fill on the sides with aluminized mylar all around (BUT sometimes placed on balcony on very sunny days, 7-8 direct sunlight). Circulation fan blowing against the wall (not directly on them, leaves move ever-so-slightly when observed, so good air-flow). Temp 78-85oF.

Soil: Organic Potting mix w/HB-101 and 30% perlite in 2.5gal pots.

Nutrients: Hyponex liquid fert (7-4-4) at day 18 (1/4 strength), 25 (1/2 strength), watering every 6 to 7 days. Milli-Q RO water, pH 6-6.5.

Progress: Day 32, flushed today. Showed sex at day 26, now starting to flower (I believe). Had lights too close, in the first 14 days (10-12 inches from canopy, they were about 3-4 inches at day 14 and stunted with just 3-4 nodes stacked on top of one another!). Raised to 21 inches from day 14-21 (then noticed too much stretch). Now approx 14-16 inches high, 9-10 nodes open (have axillaries). CFLs are kept approx 2-3 inches away from plant. Super healthy otherwise.


Can you all help to identify this, it appears only on on the fan leaves of the lower nodes (1,2 and 3), the first two pics is node 3 (same leaf, front and back), the third one is node 4. Seems like it is spreading and initially looked like splashed nutrients on the leaves, the lower node leaves look even worse and will never recover. Flushed today just in case it is some sort of overfeeding. Suspect fungal problem. Looked at it with a 60x pocket microscope, possible structures that look like hyphae of mycelium. Any solutions or ease of mind would be appreciated!
