Sorry like you said I didn't think these informations we're relevant. I am using tap water that starts at a PH of 7 and 135 ppm. I bring it down to 5.5 PH and with the nuts it shows 110 ppm (do I need a new pen ? Isn't it suppose to go up when you add nutrients?) Setup is Dwc with a air stone in the middle they were still in the tray that I started my seeds in (General Hydroponic Rapid rooter tray and inserts) I dont know about water temp i droped my thermometer 2 days ago and broke its usually around 18 to 22 Celsius, the grow room temp is 30 degrees with 50%humidity in dwc setup i only have 6 spots and the seeds that I transplanted we're "Bag seeds" as a test run so thats why they're still in that setup i wanted them to grow big enough to see which would be male and female and then put the females in the "real" setup. Also my light is 600w dual spectrum led light at 5 inches from the top of the plants light schedule is 18-6 and I'm using the
advanced nutrients ph perfect 3 steps ( Grow Micro Bloom ) I just thought I could get away with growing in a tray for a month or two or until they grow enough to see which one are females
i think your PPM meter is broken, first off. Second, don't pH until you've added nutes. That won't impact your incorrect PPM reading, but it will impact your final pH.
Just so I'm clear, I'm going to put your details into a template so it's easier to consume.
Media: Rapid Rooters, DWC
Volume of solution in reservoir: Unknown
Water: Tap, 135 ppm
Nutrients: AN pH perfect 3 part (unknown how much of each part added to base volume)
PPM/EC: 110 ppm
pH: 5.5
Reservoir temp: Unknown
Lights: 600w Dual Spectrum LED, 5" from canopy
Room temp: 30C
RH: 50%
Room/tent dimensions: unknown
Genetics: bag seed
Growth phase: seedling
Problem: ....
What have you done to try to resolve: ...
Ok, now that that's done, let's address the fact these are still in the rapid rooters tray. Those roots are quite big. You're going to have problems getting them out, which will cause significant stress on the plants. Next, I'd recommend picking up a new pH and PPM meter because your PPM dropping after adding nutes indicates either one of two things: 1. it's reading incorrectly 2. you're adding so much that it's rolling over some limit and displaying 110 ppm.
Given these things, I'd just start over. If they're bag seed, it's not a big loss.
