Looks like to much watering. Causing shit to lock out man. Cut back. Let her tell you when she wants it. It will be ok.

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 ?

There is a little bit of minor yellowing/browning in spots, on a few fan and sugar leafs. The plants otherwise seem healthy. Is this a normal part of this stage of flowering, or should I be concerned about nutrient issues? Thanks!

Do I have too many leaves? Should I have been more ruthless in the early weeks of the flowering stage? I also have variegation on one of the plants, is this a disease or deficiency? The plant seems healthy enough though

What is causing this?
What is causing this? It only seems to be on the older leaves and only on this plant. They’re all being fed the exact same.

Leaves have some spots
My auto flower has started presenting some spots, it's on week 3. But I've seen these marks since the beginning of week 2, been measuring my ph and everything looks fine. Maybe the super soil is a bit too strong, and it has to get used to it? The lamp is 27 inches away.

Getting weird brown growth at the base of the leaves on new growth... anyone know what this is and how to treat? I may add I have no signs of any pests , bugs or anything. This is a full organic grow therefore I did hit it with essential oils as a pest prevent a week ago.

Dark dots in leaves. Lamp burns?
I saw this dark dots in leaves but only she has it. She was exactly under spider-farmer sf1000 at 30 cm. Now I moved to other softer light at 40 cm. What do you think? Lamp burns? They're dry and curl up. Some images are edited for better appreciation but you have also originals.

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?

What issue is this?
I have some dark spots on a few leaves, some looks like a cal or mag def but some are a little hard to identify. What do you think these are? These haven't had nutes, about 25 days old or so, Nectar of the gods #8 fed PH 6.3.-6.5.

Their appears to be little brow spots/specs scattered on the fan leaves, I feel like I’ve seen it before but completely forgot what it was so if anyone knows if it’s a deficiency of any kind it would be appreciated. I ruled out nute burn because only one out of four has it.
