About the 3rd, 5th and 6th picture. What's that? I always assumed it was P deficiency but I got P def on another plant and it doesn't look like that. I've had the same stuff on multiple plants. Also about the 4th picture, bottom leaves drying and white-ish between veins

Bright green spots and wilting.I seem to have some wilting with some bright green spots on some leaves. I just potted up and she's at 20DLI, 0.6 VPD, 790EC @ 6.0pH. 75F, 71%RH, autoflower in canna coco pro plus.I turned my fans down a little since they were a little aggressive, so I'm hoping that's the issue.

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled. Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea. Also, when should I start feeding the plants? And how much water do I need at this point? 😥

I am noticing a weird discoloration on one of the plants. It's starting from the edges of the leaves and growing towards the middle. You can see it in the last photo. I have looked on a few guides, but I haven't been able to find this issue. Can you see what's wrong?

What could this be? Deficiency, or pests?White Crack in coco, currently late veg / pre-flower stage. Canna nutes being fed at EC 1.7 / pH 6.0 with runoff EC 1.3 / pH at 6.2. Noticed this on a single leaf this morning. Only change in last few days is that I am now filtering my water before mixing in nutes. Any thoughts?
