Yo Dirt - I think you are fine. Your plants are beautiful! Most nute charts are based on the assumption that your water is below 200PPM - ideally 100 or less. You may be on to something as higher PPM's can alter nutrient intake... I guess an RO unit is your next purchase in the quest for the ultimate harvest? I can't wait to see your final product. Following your progress has been truly inspirational!Ive got a serious question...my flush has begun, this morning before lights out i drained the res and cleaned it twice, and let the pump run on tap water for an hour before adding my 150 ml of clearex and then back to 1 on 5 off. Tonight at lights on my ppm to my astonishment was at 590. I changed the res again and repeated...guess what? 590. I filled up a glass of my tap water and guess what? 590.
I studied the flush chapter and it says you keep your ppms below 50 at flush. wow this just sent me for a loop!!!
If my tap water is 590, and ive been keeping my ppms at 2000, does this mean that in reality my nutes have been kept at 590 below 2000?
Could this be the reason why the buds didnt seem to be as big as i thought they should be?
It just never really occured to me to check the tap ppm,, and what shall i do?
Thanks.....the worried pregnant mother...
Our local hydro store is stocked on RO units as we have 700+ PPM's in our area... I personally have to deal with 700 - 800! yahoo! Are you running AC? The waste water from AC or deumidifier is often close to 0 PPM's. I read an article in TreatYourself (I think - or some other trade mag) where a guy was using a TOTALLY closed system with a 5 ton AC/dehumidifier - using the waste water to fill his resi's... he was close to 100% circulation!
