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

Problem came back
Hey mates, sup? This week the problem is back, milder than last week but still here. I haven't added anything to the soil yet and I'm worried about it. What do you think it should be? Overfeeding, magnesium, light?

Fast-growers starting to show issues.
Got some issues on these fast growers. I've been treating it as a cal-mag deficiency, however I've been feeding calmag for two weeks and its only getting worse it seems. Any thoughts? PH is 6.0-6.3, PPM 444 feed, RH 47-50%, Temp 77-81f.

Deficiency or Pigment?
I have strange brown spots appearing all over my top fan leaves at week 7 of Flower. I thought this could be genetic coloring starting to fill in, but now I think it's something more. https://media.growdiaries.com/static/post/photo/31218/4085521_grow-journal-by-livewire99.jpg

Small brownish spots forming on lower leaves. Need help with diagnoses!
Hi all. Just migrated plants to new tent/fan. I have much better environmental conditions. Now I have these leaf spots. I've included recent measurements. I was going light on the CaliMagic using 1/2 tsp per gallon. Is that my issue? Roots look good. Thanks everyone!

Just to confirm, this looks like nute burn, doesn't it?
Burnt edges, tips curled up, canoeing. I've been having trouble balancing airflow and heat in such a small tent, and as a result the tent is on average about 28 degrees celcius daytime and the plants still get a lot of wind. Looking for whatever advice you can give! :)

What should I do from here?
I had some problems about a week ago. I investigated, and corrected at my best, but I am not sure what to do from here? Do they seem to get better? Should I do something different or just keep going as I am? - More pics and info in my diary

Q1) My Dinamed #2 is looking a little concerning. Been spraying with freshly made neem water. You think its leaf miners or could it be a mag def.? Q2) I'm seeing yellowing tips on some plants (old full-leaf yellowing from pre-transplant). What could it be? Organic nute burn?

Discolouration on fan leaves
Getting a white discolouration on my fan leaves. Thought it was residue from watering with nutrients as sometimes water will land on the leaves. But it doesn’t rub off, some parts look like it’s scratched into the leaf, some parts look almost bleached. But also considering PM?

Nutrient issue
Wondering if anyone knows what deficiency or excess this could be? Thinking phosphorus deficiency and if so, should we top the main kola here? Or will it fix itself if we fix the nutrient issue? Any advice or entail would be appreciated. Leaves are not dry, soft to touch.

Opinions needed.
I have found what Might be calcium deficiency on one leaf near the top of one of my bush’s. but the rest of the bush looks super happy. Could it be light burn?? I feed them cal/mag so I m struggling to believe it could be calcium deficiency.

Spotty/Blotchy Discoloration on leaf.
What is this spotty/blotchy discoloration on this leaf? None of the other plants have it, it didn't brush off when rubbed. Hoping it isn't a mold or a pest...I have been keeping the humidity around 65% with good airflow, but I'm wondering if it's time to bring it down to 60%.

Leaves full of brown spots
My friend doesn’t have a grow diary but he uses advanced nutrients and feeds when almost dry. He has this problem on his leaves and he can’t seem to stop it. I suggested calmag but he feed it 2ml per litre on sunday and the problem is still increasing. What else can he do ?

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
