Observation and question!
I am in day 19 of 12/12 and have had no issues to this point at all, other than I think I vegged a one to two weeks to long. 3.5 gallon Hempy, 85/15 P/V. Three plants WW mainlined to 14, Ice 1 mainlined to 8 and Ice 2 mainlined to 6. Using Lucas for Hempy formula, MaxiBloom @ 7 gram per gallon. That puts me at around 900 to 1000 ppm, my rain water that I use is 61 ppm.
Looking at the plants under the LED today and saw some discoloration in Ace 1, Ace 2 and WW color is a little off but not bad. Took the plant out of the cabinet to inspect it. Here are a few pictures.
Though it is not showing up bad here on her buds I can still see some discoloration.
Not showing up as much as under the regular light but yes the some discoloration and a little leaf burn. I had attributed the leaf burn to not misting the nutes off the leaves when I feed, I do get some nutes on the leaves.
I pulled the plug at the base of the bucket to inspect the roots and there was no standing liquid in the bottom of the bucket but the stopper was damp so the system is not dry, they were fed/watered yesterday morning. pH was 5.89 and ppm of the solution was 980.

Well I decided to give the bucket a flush, so I pH'ed a gallon of rain water to 5.92 fill the bucket till the upper Perlite floated. moved the bucket around a bit then opened the base plug. I caught some of the solution and let the rest drain out completely. The pH of the rinse-ate was 5.98 but the ppm was 1296, I have never even come close to feeding that rich.
So I plug it up and refilled with pH'ed water to 5.88, did the same routine and this time the pH was 5.89 and the ppm was 1051. So I flushed and drained again just like before and the pH was 5.89 and ppm was 836.
I am going to leave it like it is and not feed/water till tomorrow as planned, but I may not feed just pH'ed rain water. I know there is enough moisture to carry it for the next 16 hours or so.
So my question is how did the ppm's increase to that point and what can I do to prevent it from happening again?
I believe the problem is caused by nute burn. Just would not expect a nute buildup in Hempy's. And since I am seeing some of the same action on Ace 2, I believe I will flush both WW and Ace 2.
Thanks,
