Hey, can someone help me detect these spots? For a couple of weeks, the pH meter has been broken, and I've been using tap water without measuring the pH. The tap water is around 7.4, but I've noticed that when I add the algabloom, it drops a lot. So, the pH has been fluctuating.

Few of the older leaves have started going yellow with brown spots and shriveling up. I'm in week 7, week 3 of flower. I've been alternating nutes with Plain ph'd water, so only been adding nutes every 2nd water. Have now changed to every water. Is this just due to flowering? TaWeek 7

What is this rust discoloration on leaves, and how can I stop it?Does anyone happen to know what is causing this rust colored discoloration on fan leaves? It starts on bottom leaves, and moves up. Also seeing yellowing on leaves, and not sure if its pest issue, light issue, deficiency, or watering concern. Super nervous plants are dying🙁

Hi all, 2 northern lights and 1 bcn critical seedlings are showing signs what I thought might be thrips, but I haven’t been able to see any bugs yet. I put blue and yellow sticky traps and still haven’t seen any bugs. Any ideas on if it’s worth worrying about and how to fix.Thanx

Deformed first true leaves on seedlingMy Harlequin x GG4 seedling has a weird set of first leaves. They are very small, narrow, look deformed and bend down. This plant is being watered the same as the other plant that looks healthy (also a diff strain, gorilla zkittlez).5y ago

Please help? All the leaves are getting discolored especially the bottom ones. The upper ones also appear discolored and she looks unwell overall. I gave her a flush on Day 78 and added bloom nutes but 4 days later (Day 81) and I am not seeing any improvements.Week 12
