That being said, the spots are something to make note of. It looks like your still in veg. Some elements are mobile and other are immobile.
Immobile takes a little while to show up on the leaf and the symptoms always show from the oldest growth, as the deficiency worsens, it moves up the plant to newer growth. Unfortunately they also take longer to reverse.
Mobile is a breeze to fix and in both cases a foliar spray is the best initial remedial action.

Tell me about your coco and any fertilizer

Thanks for the reply im slow sometimes so hopefully my replay makes since. My brain goes blank when it comes time to convert my process to writing it down. The mix im using is 50%coco 30% perlite the other 20% is worm castings and bat guano. The whole coco thing im completely new too I usually run dwc or soil. I'm currently using gh trio at half strength. Cal mag as needed. I water 2x a day sorry if I'm leaving out everything and not making since. I always ph water down to 5.6-5.8 before feed.

Just checked runoff ph is 6.5 ppm 150x10. The ppm going in is 550-650 & ph in is usually 5.6-5.8

1500ppm coming out in the runoff is high! Your ppm going in should be higher than your measured runoff. Your is backwards and your having a lock out of nutrient. Your sodium leves are rising and dropping your pH to an acidic range.

What I initially thought was not a problem, now is. I believe what your seeing is a Phosphorus deficiency. Your going to have to flush out the built up sodium in the coco. General rule is 3 times the volume of container the plant is in. So 10 gallon pot, you'd pour 30 gallons of plain water that has be pH stabilized at 6.5

Test the pH and ppm at the end. If your in range 550-650ppm don't fertilize. If your below, run 650ppm @6.5 pH until you get 1/3 runoff.

Alternate when you fertilize. Every 3 days, otherwise just add pH stabilized water.
Feed, water, water. Feed

Overall plants look very healthy. Don't worry about two leaves, but continue to watch to make sure it's not getting worse.

Stop looking at runoff. You're going to start making adjustments that aren't needed. Then your plant will get worse.

IMO don't use EWC or bat guano in coco. Treat it like hydro not soil.

You are right, but dude put in organic ammendment, so it can't be treated like hydro. The microbes and guano change the pH and will continue to do so. Plants produce exudates through their roots, and depending on what primary need for which element this will affect if the exudate is acidic or alkaline. Add this along with the influences from the organic additions. This explains the 6.5pH runoff. Which for him is what has kept his garden from really going to shit, despite the lower pH of the feed water.

Basically treat it now like it's an organic grow. Throw molasses in the water too to Rev up the microbiology and it help stabilize the root zone naturally and harmoniously.

My mix is mainly coco

I've also been using unsulphured bs mol water.

Ya I usually don't pay attention to the runoff at all I appreciate all the replies and I've been growing for awhile but I seem to learn more everyday. I still say the 2 leaves that had rusty area was from the fans scraping the trellis netting. I know this icc strain had cal mag Def when I first got her she looked pretty rough.

This is her on Dec 4th when I got her. It almost seems like they were making a bonsai or something idk. I just enjoy growing as a hobby and harvested are a bonus.

I've done this to my entire grow before and I do it alot with clones I'm not ready for yet. It will just grow back, always does!
I know many growers can't bring themselves to prune their plants that heavy.

Yes I agree seems lots just rush to get the fruit. I enjoy a heavy pruning myself. To me it seems like the plants enjoy it as well. I also don't mind a longer veg in my experiences was always worth the wait.
