You’ll know if they arnt happy sagging droopy leafs that look over watered but not. Or too crispy edges or your light burn which then you will see fans fade to white like bleachGood to know itibiti! I was concerned because of the response of some of my plants to the Samsungs.
I just did update on my wall thread one of my ppm out today I tested the bomb seeds ph and ppm out and one of them said 1900 ppm and ph6.1 lol other said 6 and 1450 lolOne of mine (Sour G) was showing signs of Mg deficiency very soon after I switched to the new lights. It's Graytail's belief that what it really needed was much stronger feedings, so that's what I've been doing now that it's in flower. It's up around 900ppm and I just flipped on Friday!
