If the soil sticks to your finger, it's wet. If not, water until 20% of the total water drains out of the bottom of the pot and check every 2-3 days.
I beg to differ sir. If it was light issues we would be seeing the buds and the leaves surrounding the buds with the majority of the damage, since they are closer to the lights than the leaves (in most cases). In most cases I would agree with you...but, the pictures say a completely different story.

Nutrient application is not being done with every feeding either. Sporadic usage of nutrients, feeding inconsistencies, etc....all lead to nute burn because it is being hammered with nutes once...the plants never truly get the benefits...

I can understand how you feel this would be lights (but...it is the lights burning the leaves due to nutrient overload).:thumbsup:
