Mars hydro setup. 24k gold & white widow

Starting off the week I ran into nitrogen toxicity in Fred. It was pretty minor so the plan was just to cut back the nutes from 50% to 30%. Also Dennis is still having issues with the black spots spreading across lower growth. I suspect phosphorus deficiency due to high ph. Lowered the ph across the board to 5.7 for the mid-week feed and it appears to have stopped the spread. However Fred's nitrogen toxicity appears to be getting worse. I will flush it out start week 5 and scale nutes to 25% for the next feed. Not much else to note, continued lst and removing some of the lower growth too close to the dirt. Nodes are stacked really tight, almost too tight. I would have liked a little more room to work with so for my next grow I want to raise lights much higher during the first 2-3 weeks to encourage a bit more vertical growth. Anyways girls are happy for now, I'm starting to collect parts to build my diy rdwc system.ill post some pics when I start slapping her together
