Ethos Grandpa's Stash Auto

Sorry, busy week, these photos are really from this weekend a bit into the next week but they're all I got. Pretty much same same for these ladies. I had noticed some mag def looking leaves on the bottom so I increased my dose of calmag plus. This didn't help the situation and I burnt some leaf action. :( This next week I am just going to go back to reg schedule. I'm gonna go a round without the calmag+ and see if that helps. The runoff ppms and pH are in a good spot. Going in about 860ppm coming out same. Throughout the week with water feeds the ppms go down to around 400. I don't think I have a toxic buildup. As you can see the yellow leaves are creeping up on me again. I'm not sure what to do. After this grow I am going to take a little review break of my grows do some online learning and try and fine tune my grow for optimal green colors. Sorry guys this next week I'll get some good photos with these ladies.
