Ignore my much smaller but still happy auto flowers.

On week 2 from sprout (May 14th), leaves are a lot more yellow than I’m expecting on one of my plants.

It’s sitting in 15gal of Promix HP, amended with worm casings and Gaia green 4-4-4, and just some mulch to help keep the sun from drying out the soil as they are grown outside.

Weather has been all over the place the last two weeks. Got hit with a BUNCH of rain the first week where i ended up having to cover the plants and even bring inside for a night, then the last week or so has been nothing but 20-30C without a cloud or breeze to be seen.

Watered the same way I usually do, keeping it as light as I can on top with an outdoor grow and a week of initial rain, and then adding water to the bottom of the pan for it to soak up and keep the rest of the soil moist, using a rain barrel system I use for the rest of my perennial flower garden (unsure of PH, but I can only assume it’s within range). Looking at the photos on Mephisto’s site for Ravenberry shows it actually does have slightly yellower leaves, but my understanding is that cannabis leaves tend to almost always start green then turn to the reds, yellows, purples based on light cycles, temps, and strain.

Internet is telling me it could Zinc deficiency, but that’s usually less about the availability of it in the soil and more about stresses the plant is exposed to. I included photo of my other plant (Putple Nuggets) that has the same soil mix and next to the one that looks like it’s having issues.

The browning on the leaves is almost certainly from me spraying them with neem oil on what I thought was an overcast day that turned out to be a lie and blasted them with 100% sun for 7 hours while I was away.

Any suggestions on what I’m doing wrong (if anything) or is it just the emotional stress from the weather shifts?
