Not sure why but I'm guessing your pH was a little high 2 weeks before this. Ok did I bingo?

sure ill play along, this looks like too much nitrogen at some point or this plant is a very picky eater, either way less nitrogen

Purple Queen show some spots on the leaves, what do you think it is?
The middle plant show some spots on the leaves, what do you think it is? 😜 Note: I lower the PH in my autopot system to 6.1. Normaly my bat mix have enough nutrients for the first 6 weeks. The dark color is because of the higher PH > to much Nitrogen intake I think.

Brown specks on leaves
I've noticed small brown specks appearing on the lower leaves. Does anyone know what might be causing this? I'm struggling to keep heat down and humidity up due to the weather. Could this be the issue or something else?

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?

What are these yellow/brown dots and how can I prevent more from developing?
Yellow/brown dots appeared midway through week 4 of flowering. More prominent on upper fan leaves. Gave it nutrient tea (flower nute/worm casting/CalMag) so hopefully that will help. Can’t test pH so difficult to tell if it’s lockout. Added new 600W light this week too.

There is some damage on the first set of leaves, I was thinking it's either due to fungus gnats which I am in the process of eliminating, or an early cal-mag issue from before I increased my nutes. Any thoughts?

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?

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.

Having persistent yellow/brown spots on my leaves. Took a close up picture to show them better. I adjusted my nutrient schedule to increase phosphorus content. pH is checked daily. What else can I do to eliminate the problem?

Hydroponics, i need a second or third pro opinion. Just a Deficiency? bad pH? (I alreadt did a partial water reservoir change tho)
Yoyoyo! If someone of knowledge could help me here, I would be grateful So I think it's a Magnesium deficiency, caused either from my too low pH (5.2) or too much CalMag (only used 1,5ml on 10L) I gave a more in-detail description on my diary. lower leafs are "crispy", not smooth

Any ideal what this is I've noticed it a few times before. It's like something has sucked the chlorophyll out and it leaves a see thru place that browns and rusts up. Mites, deficiency, excess?????

Is this just genetics or deficiency/disease?
Is this mottling some kind of deficiency or disease? or is it just a genetic variation? This Sour diesel had a two toned leaf at the 3rd node and had this mottling from the start.
