Yes, very impressive for 13 days. Looks good man, love seeing good results w/LED's. Just started my own LED log, check it out. (shameless plug...sorry)

Well it's been a week since I've updated anything here. Changed the nutes today. PPM are now 1150 from 960 on the last change.

I was topping off with Liquid Karma in between changes. The plants didn't like it however and dropped pretty badly each time I've done it. I've been changing the solution every week for a fresh batch.

I've finally got the PH staying quite nicely at 5.8. Here are some pics from today. Tallest two standing at 16" tall.

Hey,

I'm having some trouble from this weekend. I didn't do anything that I think is different, but the plants aren't happy. Please see the pictures below.

PPM around 960. I lowered it to 820 with some PH 5.8 tap water. My tap water is 160PPM.

I can't tell if this is Magnesium, Potassium, or a Chlorine problem. Over nute in general??

Any help to get these back on track would be appreciated.
