Burnt Foilage?

[KannibisKing]

Hey all, just a quick pic.

Was just wondering if anyone could identify exactly what this is? I think i may of had my light a little too close, and temps were going as high as 32 degrees the past couple of days(hot weather) its cooled down now and gone to its usual temp.
I have 2 girls in the tent pretty much the same size, but this is only on 1 of the girls? So makes me think it can't be a heat problem because surely it would be on both?
Anyways i can't find this anywhere so thought id see if one of you guys knew. If you need any info just click my link. Thanks in advance.

I started to feed cal-mag on week 5 around a week ago 0.5mil per litre, then this happen, its at the top of the plant. From my experience calcium works its way up from the bottom, correct me if im wrong. Namvet do you think the problem may be using a liquid fert cal-mag such as Plant Magic's Ca-Ma+ locking out my nutes? I use organics(biobizz range)but have never had a organic ca-ma supplement. I have just ordered Humboldts Equilibrium so hope this helps? I dont usually check my PH either because soil/nutes ect is spose to buffer it. But i always run into same problems around week 6/7. Also the 2 girls are getting exactly the same feed and this is only happening on 1 girl?

0.5 ML is only 1/8th tsp per gal.I use Gen Organic cal/mag at 1 tsp per gal for light dose and 2 tsp per gal for heavy dose.

So possibly up the feed to 1mils per L? I should have humboldts equilibrium 2moro so that should help, but i dont want to blast it with cal-mag if its not the problem, do you know if this is the problem? Thanks.
