(I can fill out a form if it helps, but im growing in a closet with PLENTY of ventilation, one 1000w hps, coco-blend soil, and watering with a custom Earthjuice formula.. )

(also Neemed at first sign of pinholes, hoping it would stop mites, and had NO effect)

are you spraying them with water, or when you water normally leaving drops of water on the leaves?

looks like burn holes from water to me.... but the pics are incredibly small and hard to see... might want to see if you can post a larger one.

i had an issue like that before. it was from the light being too close to the canopy. the heat made the plants leaves undercup like that.

Yes, i do spray them down daily, and i'm on 24/0, so its possible just water droplets are causing the light to cut holes in the leaves?

I will try raising my light, and if that doesnt help, i will go to 18/6 and spray during the dark cycle.. I'm just happy it doesnt look like some kind of phantom bug thats wreaking the havoc.. :D

Switch to 18 on 6 off, and only spray at night... I usually do it an hour or two before the lights go on if possible.

Bugs can wreak havoc quickly, what was once a small problem is a nightmare pretty darn quickly if you don't spray and stay on them. Try to keep your temps down too if possible so they reproduce slower

yep, it can happen... every play with a magnifying glass to burn wood out in the sun as a kid? water will focus the light in a similiar fashion as the magnifying glass, if the focused light gets too strong it'll burn a hole.

Hey, thanks for the info, and the reassurance, haha :rastasmoke:

This seems like a chill forum site, you guys are all right


Anyhow, i did the cycle change, and have refrained from getting water droplets on any leaves during last 2 waterings. I'm 90% sure there has been no new holes cut in my leaves, but i wont be sure for another 4-5 days...

I wish i would have found this site a few months ago, i would have done a grow / project log, since i built my entire setup from scratch.
