Hello, my setup is:
4 gallon Stealth Hydro DWC
2 85 watt compact fluorescents (flowering and grow)
Stealth Hydro Grow and Flower Nutes
GH Flora Shield
After about 2 weeks, my first change of nutrient solution, plants looked great and grew very fast. However, after the nutrient solution change, problems have started. I set the PH at about 5.5-6, every evening its back to 7-7.5, the solution started to foam and a brown residue formed, inside the tank its a mess - brown foam and residue, smells like an old aquarium. Reading the sites, this sounds like a algae or similar problem, so i flushed and cleansed with bleach and added GH Flora shield. I continue to have the PH issues, set to 5.5 it runs up to 7-7.5 after 12 hours, and the tank is starting to smell and i suspect will have issues again with foaming and brown residue. Because of this i think the plants are starting to suffer, see pictures (yellow leaves on the bottom). I contacted stealth hydro they said change the water (i used tap water) to distilled. Also, i was running about 800PPM, it tends to go down over time. But the foaming, brown algae, and severe PH rises I can't get seem to address. Anyone have some advice? thx in advance.
