Calmag Deficiency? Yellow Spots

dusterpstarted grow question 5y ago

Last res change I saw some yellow/brown spots on the fan leaves up where the main cola was getting too close to the light. Is this a calmag deficiency or light too close? I moved the light up to the top of my tent with zip ties and got back several needed inches. See pics.

Looks more like calmag but if its starting at the bottom leaves then you should consider a lack of potassium, when its at the upper section that's when its calmag. Stay lit growmie, doesnt look like light burn.

Moving the light was a good call. In flower with that light, you want to be around 18 inches plus or minus a few. You can also try feeding at a ph of 5.9 for a few waterings. Happy growing.

Discoloration and burnt edges on leaves Can someone please help me diagnose this problem? At first I thought it was root dry spots from the drip watering system but it’s gotten worse. The bottom leaves are yellowing and the edges are burnt with a hole in one of the leaves. Anything helps, thanks!

Yellowing Budsights Early Fower (organic grow)I fed the plants yesterday and noticed that it was too warm in the tent. (86F) So I change the light time to 9pm-9am. As a result, the plants had 24 hours of darkness in the tent. When I turned on the light today I noticed that some of the buds had yellowed. pH (soil): 7,8-8,4

They say yellowing is normal, but this much?Not sure what to do. First time with autos, and they're around 69 days old. Breeder says 60-70 days mature. Used living soil. The yellow has climbed both plants yet the trichs are only 15-20% amber. Will my girls be okay? What kind of TLC can I give them until harvest? Noob here
