dont have the money to buy an electric meter and i hear theyre not all that great anyway so i was hoping there would be another solution to my problem.

Thanks to anyone that can help me:jointsmile:
Buy a digital 4 in 1 soil tester off of Amazon. I got mine for $30 and it makes growing the plants almost too easy. Look for the KCB yellow one if you decide to go that route. It has a digital PH tester, Soil mosture reader, thermometer, and sunlight meter. It will help you find optimal conditions for your plants.... regardless of what others say.

Dark brown water doesn't sound good.... sounds like it might be too heavy of a compound. What nutes are you using and at what ratio?
