Fan causing curled leaves?

[F.A Hayek]

Hey guys,

I recently added a small oscillating fan to my grow room and I've noticed some leaf curling. The fan is about a meter and a half away from the plants on a very low fan speed - just enough to get them shimmying.

I also noticed some yellow streaking on my Northern Lights plant which I suspect may be nitrogen deficiency, however the leaves aren't yellowing from the bottom up so I can't be 100% sure.

Any feedback would be great, thanks!

Probably getting toxicity from the DMG. Lay off it for awhile, they are fragile while they are young. Fan is fine, builds muscle

your soil looks like it needs some aeration,looks pretty compacted.

Thanks for the reply guys.

I played it safe with the DMG at first but after a feeding of 400PPM they were still looking hungry with light green / yellowing leaves. Since I've stepped up the nutes to between 500-700PPM they've exploded in growth.

I'll roll back the nutes over the next few feedings to see if they improve. The curling happened as soon as I added the fan, but I guess it's just a fallacy of correlation.

It's just straight Coco coir that I had left over from a previous grow. I couldn't find perlite or vermiculite in my area at the time ( sold out everywhere ) which was a shame. However, I managed to snatch up a few bags last week which was great! Just in time because my Sour Diesel / New York City Diesel seeds are just about to pop.

Was going to also say light green leaves could need more nitrogen.
