Is something eating my leaf?

[RemzBennz]

4 weeks flowering and ive found a leaf that has marks that look like it has scabs and a couple of the scabs look like they are going through the leaf gradually. Few leaves on the lower plant are drying out just on the tips and crumble when you touch them. Any ideas?

It looks like insect damage so check the entire plant and underside of leaves for insects and also check your soil.I can't see the tip burn in this picture but it usually means nute burn.Post back if you find anything.

Hey Namvet thanks for the reply☺. Ive had the odd lil black fly zooming around in the tent when ive had the flap open but nothing major. Ive found a few more leaves with the same markings and theyre all in the same area. Im going to thru both plants as you suggest as i see yr a specialist and see if i can see anything. Ive been letting the top inch of soil get dry between watering over the last 3/4 days hoping to prevent any eggs in the soil. The plants are drinking 1L of water daily with 7ml of bloom added as the directions on the bottle suggest and once a week im adding 1ml pk boost to the feed, again as suggested.
The leaves that are affected in the that area are about 4" above a 6" desk fan, could these leaves be getting windburnt from the fan?.....
