Need Help Diagnosing Two Plants... +Rep

Been having a little trouble with these two girls. They are outdoor in 5 gallon pots of FFOF, been getting just a little bit of veg nutes. Any idea with what is wrong? It has been getting hotter lately, although I think they have been getting enough water.

Plant One:




Plant Two:

They look fine. Sometimes a leaf or 2 get that way, but no need to over analyze. I do see the tips are a little nute burn, but I would not worry or change anything.

It looks like nute burn to me man, see how the tips are brown and "burnt"? Those small yellow spots? I wouldn't worry though she'll be fine, very mild case.
