If you had leaves wet under light, possibly lightburn.

I'd guess a calcium and/or magnesium deficiency

It's been a week since I switched to flowering and new growth on the plant all has a yellow/lime green colour but this seems to go away when the leaves fully grow out and growth in general has not slowed down. Based on the pictures in my diary should I be concerned?

Slight Yellowing on tips of new-growth? (VEG)
Why am I getting slight yellowing on the ends of new-growth leaves? It's affecting every plant. The only clue I have is that it might(?) be related to very cold nights because of my re-vegged photoperiod showing purpling on the edges of its leaves. Any ideas?

Discoloration continues
Pattern seems to be progressing. Brewed molassas tea with alfalfa, kelp and worm castings. Spots worsened so I treated with CalMag last night. Thought I would post to see if I could get your thoughts.

Yellow tips
Dont know why but one of the girls is suffering from stress. I think this is the cause for the yellow tips or do you have a other opinion? I did LTS training every two to three days, maybe therefore? A other reason could be light burn. But with a distance of 50cm I dont think so

Yellow / Orange spots
I have noticed some yellow / orange spots on one of my plants, can anyone help me find out what it is? Deficency? Rust fungus? I use Leaf Coat from BioBizz two times a week.
