Hi there, does anyone have any idea what the slight mottling is on the leaves of two of my plants. There are close-up pictures under Day 27 in Week 4. The discolouration is present across multiple leaves, but seems to only be happening to two plants out of 8. Thanks!

I suspect the mottling is a combo deficiency between Ca and K, though I'd go so far as to say that both look minor so maybe not try to fix either. If you're using nutrient salts you can isolate a specific element to tweak, but most nute brands have multiple things mixed in the bottles so if you tweak any thing, you end up tweaking several things which will cause other problems.
If interested, I made a tutorial for using Hydro Buddy to reverse engineer your nutrients, then you would be able to play around with tweaking the nutes in theory before actually changing anything in practice.

Help Identifying Ailment! BlackBerry Auto on week 6! Nutrient deficiency? Cant find anything online similar.This is my second grow since switching to hydro. Growth has slowed a lot. Leaves are getting brown spots and almost look like they're being eaten but no pests can be found. No root rot, I dont think I'm over watering them. Since I started hydro it's been a real challenge.

Yellow Leaves AutoflowerNovice grower, Outdoor. Started in a 70/30 coco-coir to perlite mix. Forgot Worm Castings until 22nd June, implemented with top dressing of Gaia Green Power Bloom and All Purpose. Overwatered at stem for a week or so. I suspect it's either an N, P ,or K deficiency (nuteburn?)

A bunch of different leaf symptoms appeared over just a few hours, can you spot the issue in my detailed diaries and solve the mystery?Everything was well, until over just a few hours they developed all kinds of symptoms.
I have 2 diaries here for the grow, the 2 called “Grow #2” and I am very detailed about what has been done day to day.
So please have a look and see if you know what might be happening

Is this septoria or alternaria?
The plant is doing well, buds are not affected (at least not now) so I hope it’s septoria. Few weeks till flowering complete, do you think I can carry on with it?
Please tell me it’s septoria and not alternaria. Thanks to anyone that will respond

Leaf edges a bit yellow and now some yellow mottling. Signs of the same problem?Leaf discoloration now on a few leaves.... Could this be continuing signs of an imbalance caused by switching nutrients for the first week of 12/12? Please see my previous question about yellow leaf edges and Sciolistic_Steve's answer. I'll be switching nutes tomorrow anyway...
