Nutes or Insects?

[Stone420]

This is a Blue Dream outdoor auto in Ocean Forest soil. She has been in the soil for about a month, so I haven't starting much feeding yet with the exception of a tiny bit of organic earthworm castings and bat guano. Her pH looks stable in the mid 6's based on a pH soil probe test.

I also spray weekly with Spinosad or Neem Oil with a drop of Castile soap.

The damage seems light isolated to a few fan leaves here and there. I think a bit of wind damage may have made a tear. Overall the plant looks fine with the exception of a few fans like this one. There is a tiny bit of crusty edge at the top, so this makes me question nutes. Any advice is more than appreciated.

I'm not the expert.

Looks like an issue with something that may have been sprayed.

Very possible. Unless I am mistaken, I don't see this as a nutrient issue - either lack of or excess.

Are you spraying when it’s getting full sun? Could be burn spots from water droplets magnifying the sun. Spray at sun up or down if not already. Just a thought I don’t grow cannabis outdoors

Good thoughts kind sir! Yeah, I always spray close to sunup so the droplets can dry and be safe for the plants. I'm out feeding my horses that time of day, so I water and spray my girls at the same time. These spots could actually be droplets of nutes that are splashed up on the lower fan leaves. I don't think it looks like nute burn tho...I am puzzled.

Physical damage IMO,.. not sure exactly what though! Through and through leaf spotting does smack of possible lensing effect, but it's super rare, unless those few leaves just aren't dry in time,.. that seems unlikely, but.... Infection is a possibility too, but if fungal the neem should deal with that... bacterial, no,.... The whole point of adding the soap is to knock down the beading so that shit doesn't happen in any case... Are you sure of the dilution?

I've been very careful to measure the mL of all spray solutions when mixing. I do spray in the early hours so the sun doesn't burn, but the plants are usually covered in dew droplets early when the sun rises. Could be a variety of things, but I wanted to make sure it doesn't look like a nute related issue. As long as the feeling is that this is physical damage, I'll work on controlling the spray and/or other physical aspects of the grow. Thanks!
