spotting

What are these light patches? Is this calmag related? Or is it something else? Tried adding a little bit of calmag a few days ago in hopes the deficiency would slow down but the newest growth still shows it indoor grow, pH is 6.0 consistently, ppm reads about 500, and I’m 3 and a half weeks in...

Just wondering if anyone had any ideas of what the spotting on the leaves are or what they may mean. Started to get them a few days ago on some lower fan leaves now I got them on a newer cola. Growing outdoor with supplimental lighting in pots with ocean forest potting soil but I have no real...

Please help me. I can't tell exactly what's going on with my plants only one is having issues right now. I'm going in FFOF soil only and using the FFOF trio nutes and molasses. I am a little over 4 weeks into flower. My water is R/O with calmag and nutes is probably about 1000ppm including the...

A couple leaves on each plant have been spotting like this and getting worse but verrryyy slowly, and the second set of pics are a little different, only the bottom leaves on seedlings spot up yellow, then the whole leaf turns yellow, they spot up brown, and then die, perhaps over the course of...

ok so my plant grew into my light a bit the night before last and I noticed the very top leaves had some discoloration. I thought this was light burn and probably is but this morning I noticed these spots on a leaf a little further down. I’ve looked at a bunch of pictures and posts but I’m still...

Hey!! The spots aren't from space, I'm sorry, but hopefully that grabbed someone's attention. So, this is my first post to a forum and my first grow. I have six four-week-old plants under t5 lights for about fourteen hours a day with an oscillating fan on them. I intend to place these babies...

I was wondering if anyone could help me diagnose my current plant issues. I originally believed it to be a pH flux however stabilizing the water and nutrients pH(to pH6-7) did not help said issues. Some info: *Indoor Grow *Watered via lift method(1-2x weekly). Alternating nutrients(Fox Farms...

First of all I'm a total rookie. First grow. Had this girl for about 8 weeks. In straight ffof. Watering with tap water lowering ph to 6. 300w led light. Temps are good but humidity is on the low all the time. Around 30-40%. I have been misting leaves. No nutes at all yet. when I first...
