smoknjo, cool to hear that things may be leveling off there. sounds like you got good temp and ph there. i said earlier that the rez temp is best between 72-75 which is an NFT system i have.... i like it at that temp because by the time the water makes it to the gully then i suspect the water may have dropped a degree or two before it gets to the roots... what kind of system do yoh have. ?

Kan Man said rez temp should be 66-70 which i do agree with if you have a system like bubbler/ DWC system or some system where your roots are touching your water in the rez... and that temp range is a bit safer IF you have some light leaking in somewhere where algae can start to grow and the algae does like warmer water temps. but if you have the light under control,,, then the roots like 72ish the best.

however IF your room temp is way way high, the you would want the water to be a bit cooler then 72, and if the room temp is too cool, then the water should be a bit warmer. sounds confusing so i should stop. it is just a nice science of balance that you should just be aware of but not stress over. happy growing!!!
