Thanks for the comments guys. Yes, getting old sucks, as I've been out already snowblowing my way out the driveway--heavy stuff!
So, I have yellowing of the top leaves on my GG4, edges turning up some. To hot, to much light, to many built up nuets, a deficiency? Haven't tested my PH...KISS grow.
Going to try and get some cal-mag tomorrow morning and give it a shot. Also try and get my light up a little, I'm about out of overhead room for sure.
Very funny LTG! LOL, I hear you.
It's especially hard for me, my plants are less than 10 ft from my comfy recliner(g), I can turn my head and see them.
