The title pretty much says it all . This is my first RDWC run, and I'm having trouble figuring out my problem. Quick insight:
Bottom Left: Critical Plus (2 weeks from seed)
Rest: Purple Wreck (4 weeks from seed)
Running an EcoPlus 4 (12 watt, 9L/min), and Ecoplus 2 (6 watt, 4.5L/min) to oxygenate approx. 200L
Was running ~150ppm of GH FloraNova until the Critical Seedling could handle more
1000W Digilux HPS
Air Range: 20-26 celcius
Water Range: 20-21 celcius
Humidity: 25-45%
Ph: stable around 5.8 (+\- 0.2) [until algae broke out]
Everything was growing well, no burning, deep green colour, until I had a bad run in with algae/cyanobacteria a week ago, right after I added some GH benefical bacteria. Did a thorough flush, and wipe down of all surfaces with H2o2, and added 7ml/10L of H2o2 (29%) to the new water for precautionary reasons, and did a H2o2 rinse of the roots. I left all nutes out of the water for 2 1/2 days to make sure algae didn't return. I then bumped the PPM back up to ~150ppm. No more signs of algae for the last week, but the plants have stopped growing all together. They started losing colour from the bottom, and the yellowing is working its way up the plant. Colour loss always originates at the tips, and works its way towards the stock. As seen, the tops are "clawing inwards" and colour loss is starting to happen on the tops now, while the bottom leaves are drying and dying. The roots are firm and look healthy (slight brownish tinge from nute stain?), but no slime or mucus on the roots.
My two theries are either theres still some form of the algae choking the roots (so I'm doing another H2o2 bath for the roots), but this seems unlikely with no mucus; or that the pumps I bought provide way too little O2 for the water and my guys are suffocating (though H2o2 should add O2 to the water and have helped correct this?) I'm at a loss at this point, as my experience has always been with soil. I seriously need some experienced insight into this!
