Hey, to me it looks like you sprayed your plants with something during when the lights are on. If so, you should never spray plants with lights on, always have it off. Nutrients burn leaves under the light.

Blotchy Leaves Problem - January 27 (Day 23)In the last 24-hours all three of my plants have started to show signs of blotchy/irregular colored leaves. When I touch the blotches they are crisp to the touch. I have a really cheap pH meter, and I've been feeding at 6.5 pH. Is this a pH issue?

Brown spotting?Hey everyone!
My plant is in her 5th week and a few days ago (around day 30) I noticed some brown spotting on a few of the mid/lower leaves. Does anyone know what this could mean?
I gave her her first feeding 3 days ago. 1/4 strength veg nutes and 1/8 strength bloom nutes.

Nutes too early?The leaves of my northern lights look a little brittle and discoloured, maybe the small amount of nutes I gave were too early?

Need advice as soon as possible. Please see last few pictures of DoSiDos week 3. Am I looking at mottling here? Soil ph maladjusted? Please help if you've seen this before, and what steps do it take moving forward (or am I paranoid, IDK). Thank you!Week 3

Started LST but now plants look a bit sick?I attempted to do LST but I think I've maybe started too early as some of the leafs started to wilt kinda bad afterwards. Was careful not to break anything. Edges are curling and have discolored. I have a feeling they're a bit short too?

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
