Hi , i have a rdwc hydro setup , with a good oxyge...

hey there, the problem as you know is the pH, you absolutely need the pH down, i prefer the power stuff, just make sure that it's safe for hydroponic use, GHE is releasing some pH down in powder form. You should be aiming for 5.8 pH not 6 or 7, 5.8 , after all the pH of rain water is 5.5 right? apart from the pH down dont change a thing ! hope this helps ! 🚀

I would suggest that you boil the water that your going to put in your system first . This will help take away all the chlorine and some impurities from the water . Then let the water cool over night , once cooled you wanna add your nutrients and PH correct your water to 5.5 5.8 . This technique will help you keep your PH at regular levels more consistently in your grow . Your PH is far to high for a hydro system this will cause you a variety of problems in the future such as nutrient lock outs and stunts of growth because of the lock outs . When you decide to lower your PH to a range that more acceptable for hydroponic style grows I advise you do it slowly so you dont shock your plant and stunt its growth for a good period of time . I hope this information helps you to understand what some of your options are to help maintain that PH level in your re savoir as well as the PH range for a hydroponic type set up . Other then that your plant looks like its going to be big and beautiful :D. -Happy Growing!

With the rising ph it sounds like the water itself. I would maybe look into getting it tested to see for sure an why it is rising the ph. An R.O system would deff help. other than RO there might be other filter systems you could add but if your going to add filtering system you might as well go for the R.O then you know your starting with a clean slate. hope it helps and good luck!😊
