So, i've had my indoor hydro setup going for about a month now... had many hiccups along the way and now i'm in the middle of the [next] problem. Problem... my plants look somewhat yellowish in color and darker in the veins of the leaves. This problem occured overnight after adding a water heater (meant for a 20gal fish tank) putting the water temp up to ~80°F (normally was around 65°-70°F - which i now know what the optimal temp). I've had the Canna nutrient solution in there for 4 days (i change every 7-9 days). I have my suspicions as to what the problem is based on these facts: i had the the water heater plug tucked in between the lid to the reservoir and the tub, thus perhaps allowing light into the nutrient solution. To add though, i've had a bit of light exposed to the reservoir already filtering in through the hole where the water pump's outlet hose and power cord comes out... through the last 2 cycles, i haven't had any problems. My suspicion is that i may have introduced a rapid growth in algae due to the water's temp rising and the addition of light into the reservoir. I'm low on nutrients at the moment so i'm trying to refrain from dumping this cycle and just adding a hydrogen peroxide solution to the mix [of 20 gallons]. **Some other info about the system: General Hydroponics 36 site 600watt air vented hood (currently in VEG cycle) R.O. water Canna Nutrients Part A & B(supposedly with this nutrient solution, no measurement of PPM is required as long as you increase in the specified increments as the plants grow with each nutrient change) Drip Clean Rhizotonic (another Canna product) CALiMAGic SuperThrive Air Temp 72low/80high R. Humidity EDIT: btw, i'm already disliking this whole *everything is one paragraph no matter what* style of the forums... anyway, i planned on going with a 7ml/gal hydrogen peroxide solution (for 20 gal reservoir). Would you agree?
