Hey guys, So recently I have been noticing something affecting my plant. At first it was droopy and looked like it was close to death honestly, so I watered it and figured out that was the main issue which was being underwatered. It then perked up a bit but continued to yellow and some leaves started to crumble a bit. Now I'm witnessing some spots on my leaves and I'm not sure as to why or what from. I think it might be a cal-mag deficiency but I water with tap so I wouldn't know why a deficiency in cal-mag would be present. Any suggestion as to why I'm seeing these spots / yellowing of my leaves. ? My plant is in week 6 of flower and I'm feeding it ; Kool bloom 10-10-10, Grow big ,and hydroguard. Let me know what you think could be the issue .
