DWC: PPM 1500 DROPPED TO 1160 PH STILL 5.9 DRANK 32oz 2-3DAYS?

Smh I mixed ppm an ec that’s good ec 1500 ppm 750

if she is drinking more on a reduction of the ppm she is happy and making up for what the high ppm restricted give it a week and she should return to normal

I would say that is about rite for a younger plant. A drop in ppm is normal over a few days, Ph being constant is fine as well. But 1500ppm seems a bit high for your stage I think, unless your water is already very high in ppm to start for some reason? Only feed half of what it says on your feeding chart for your nutrients for DWC to start off, then go from there by reading how your plants react to it and add nutes or dilute accordingly. I also noticed in your DWC diary that your night time temps are a few degrees Celsius higher at night then your day, is this a typo or is it so? If so you need to drop your night time temps below your daytime by a few degrees instead. They need cooler nights for sure just like in nature. Hope this helps! Cheers! 💨
