Hi there, i'm at my first grow and its Hempy.Im growing two months now and plants look ok but i get confused about run off PH and EC.What is correct run off?
Coco/ perlite 50/50 , coco chips at bottom.
3 buckets. 3gal. 7gal and 9gal.
to me looks,the bigger the bucket = more problems...
For example
3gal IN ec1.4 ph5.5 OUT ec0.85 ph6.4
7,9gal IN ec1.6 ph5.4 OUT ec0.5 ph7
Ok big buckets are beds with more plants,they eat more.
Main problem is of course PH.No matter how low ph i put in or how much i flush it always stays high.Its because of bad media i think
Other question is how much EC should i see in run off? Today i started to flush.But with every gallon of ec1.4 solution i get only ec0.1 increase in run off.So to reach IN target from ec0.5 i would waste a lot of nutrients.Sgould i flush it with stronger solution like EC2.0?
Everyone complain about too high EC in runoff and no one complains about too low so i couldnt find an answer,sorry
thanks
Almost forgot i handwater them once everyday till 30% runoff.Water is RO.
Fresh coco i rinsed with RO and after soaked in ec0.4 phd solution but in the morning solution was like ph7...I though it will buffer but...
