Hi Tvanmunhen I was wondering about the yellowing of the leaves you had at post 47. Where they underfed, caused by the light or just looked more yellow because the led light is on during the photo? Your current grow seems much greener. For me it seems really hard to judge the color of the leaves under the led even with the Vivosun uv blocking glasses. I had to turn the light off and use a flashlight to see the actual color. I have never had an issue with hps, well maybe a small issue back 2009 before I realized I needed to add cal mag. This whole led light has me learning all over again.
thanks in advance and very nice setup

Hello, thanks for checking in. Issues with dry backs and over watering. I'm absent often and didn't have a handle on watering yet. It also didn't help that I was revegging them from 12/12 back to 18/6 so they were already stressed out. So ya poor girls got a little yellow lol.

I was able to correct my watering issues. I also used Epsom salt, fish fertilizer 2-4-1 and spirulina powder to get them going again. Unfortunately the damage was already done on some of the leaves. I tried to keep the light intensity around 800 ppfd according to my cheap photo Bio meter and ride them out. To my surprise I ended up getting some great smoke despite my neglect. :weed:

Hopefully that helps. Good luck on your transition to LED!

About 3 weeks 12/12. The closest tops are about 10" away but the majority are 12" to 14". With the light at 100%, most my readings are 850ppfd to 950ppfd. PXL_20230731_174159227.jpgI noticed a little bit of color change on the tops closest to the light.They were really close the the light for a few days(8" or less). I tied them back a bit and decided to keep blasting it.
