Gidday Ive been given a ec pen but its in ppm now where I live we have crap water,the readings from the tap water
are 450ppm am I supped to add that on to my nutrient reading like if I wanted to run it at 1450ppm is that included or is it 1850ppm if that makes any sense
Thx Nods

Yeah man, that is included, if u wanted to run at 1450, then u need to add 1000ppm to ur current water.
U can run a purifier to drop that down tho, and u can get more nutrient in it without getting a higher ppm.

The light should b ample room, that sounds like a problem either a zinc/iron deficiency/toxicity.. Always hard to diagnose without pictures.

Guys at my shop are just interested in selling new gear... they have absolutely no gardening experience, or the ins & outs of the gear... sad but true. That pen may be calibrated to one of 3 scales which will effect how the cal solution you use actually reads... some ref solutions only list for one particular scale. More info on the actual model/make of the pen will help. That being said, my tap comes in at 830 on a 700 scale. RO it brother... 20. Peace.

Hey Growhi your right the pen was out by 220 and said the same about the
3 scales they calibrated it for me know problems! thats a heap out
Have a good one Nods

Yeah Grohi,
sorry to hear about your shop guys. I can't blame mine though, never thought to ask, just bought the solution. Never hurts to ask?
Thanks
