im growing 4 autos (which are very happy) I’m using a needle drip system firstly when I do my nute mix my ppm are around 500 until I add ph down which lowers the ppm by about 100 (186ppm is my tap water) so around 400 - 450ppm after ph down. Is this normal
Secondly during the week between each water change the reservoir evaporated I need to adjust the ph but I don’t add more water because the ppm decreases, it doesn’t increase as the water becomes more concentrated. I read my ppm this morning and I’m at 180 which is less than my tap water to start.I last changed the water Tuesday I have at least 3 days before i change. Are my plants eating everything? I’ve i go higher on the nutes I’ll burn my autos thanks for any insight
