Chemical Burn?

[zacmaster]

This is are first time growing and have just entered the flowering stage. However some of the tips of the leaves are looking like their burnt and are curling under. About 3 days ago my roommate sprayed them with Age Old Kelp and am wondering if they have chemical burn. I have included some pics and any advise will be helpful.

age old products are organic products so you shouldnt have chemical burn
from the tips in the blurry pics/my eyes could be from a nutrient burn

what type of medium are you growin in
foliar feeding is great for correcting defeciencies.
just give plain ph'd water for the next 1 or 2 waterings

Yes...without better info and better photos it's pretty tough to say what the issue is.
