Dang, hard to really see in that light. Looks like more like a deficiency than an over dose. What nutrients are you running? Another things that comes to mind with the pics is bleaching from the light being too close and temps too high. But really need a little more information to be able to point you in the right direction.

the nutes are a powder 13-40-13 and 3-11-38 mixed 50/50 tonget me to about 8-24-24,temps 22-23.5 c day,19-21 night,first the big fan leaves started to dry out like a P deficiency ,then i moved the EC from 1.2 to 1.6-1.7 in about 5-6days that was maybe a little to fast,then i saw in the last 2-3 days these burn marks on the upper leaves like the lights are too close but when i put my hand its not hot at all,i keep these 600s on about 40cm from the tops,cooltubes and a strong fan pulling air through them,today i mixed some fresh water in to get the solution to about 1.5ec,the same clones on the other table are 2 weeks ahead and i keep em on 1.7-18ec
