That's a Northern Lights Auto there on the left (Candyland Auto on the right). The NL is a little over 2 weeks into flower. She was last watered yesterday with just a little CalMag and PH UP mixed in. (PH was low when I watered and gave nutrients earlier in the week) What do you all make of the spots and the yellowing and the burned tips? First grow so it's not easy for me to identify which growth is the newest. Thought I had overcome some calcium deficiency a while back, but I suppose the CalMag wouldn't be working so great if PH was really low. Also it looks a little like nutrient burn and it's creeping closer and closer to my light. Thoughts? Also what are you folks using at this stage when it comes to feeding from the Fox Farm pack? Thanks so much for any comments and recommendations related to anything anyone sees. Have a great Friday friends.

Maybe a slight calcium deficiency, looks like you have alot of plant there, might need more than what your feeding.
What grow light are you using and how far away is it from the top of your plant?
Hi, how low was your PH? I'm thinking the low PH caused problems in the uptake of some nutrients like calcium.
It also looks like a bit of Nutrient burn so that could be part of the problem as well. Autos are more sensitive to nutrients than Photo Periods so make sure you are feeding them at half strength or less.
If you can get us your run off PPM and your PH levels, that might help figure out the issue.
Good luck
