Dark spots on leaves forming
Benasquellastarted grow question 2 years ago
So this is two separate plants I've got brown spots forming at the top.
They're both about 4 weeks into flower. Watering every 3/4 days (4/5 litres each) with nutes. Humidity around 50% 26 degrees day time around 20 at night.
Any ideas?

Raising your light is always a smart move when something bad is happening. Slowing down photosynthesis slows down everything.
Autos at 4 weeks of flowering are at peak flowering and starts to swell up: She is hungry mate. Looks like P and or Cal deficiencies from here. QB style Led board are notorious for pushing the nutrient needs higher, especially for P, Mag and Cal, where the light hit the plants. You need to increase feeding.
Frying some sugar leaves or top fan leaves is bad but not a catastrophe. If your 2 lights are at full power in your 2.3'x2.3'x5.2, that is a lot of light. Raise your light again if you can.

Ph imbalance and water smaller amounts just more frequently. That’s what’s causes the rust

I've also tried moving the light away a few inches but it doesn't look like light or heat burn to me.
Water pH is around 6.5 doesn't stray too far from that.
I'm using canna terra flores 5 ml per litre, rhizotonic 0.5ml a litre, cannazym 2.5 ml per litre cannaboost 5ml per litre and advanced nutrients ph perfect micro notes.
As for lights I have a marshydro ts1000 and another 120w led
Hope this helps you help me peace team

Calcium deficiency?Hello everyone,
I need your help once again.
I have just spotted some brown/yellow dots on 2 leaves of my plant.
Did some research and looks like Calcium deficiency, but still wanted to ask you.
If that's a Ca deficiency, should I add CalMag next time I feed her?
Thank you ✊

Rust spots on leavesHey guys, please help me identify the cause of these rust spots on leaves. Seems to progress in last couple of days(spread).
Might this be a light/heat burn? Or some nute def?
I added CalMag on previous feeding.
Distance to light is 32cm currently.

Brown spotsHello everyone,
I have to ask the same question, since that problem is spreading although I give her CalMag.
9 days ago only 2 fan leaves had those brown spots, now almost all of them are affected, especially higher ones.
I wanted to feed her once again and then start flushing

Brown spots on healthy leavesBrown spots developped on seemingly healthy leaves during late vegetative state. She's at ~40 days old. I haven't changed her feeding habit. Soil pH is between 6 and 6.5. Water pH always making sure it is 6.5 before watering. Could it be Cal-Mag deficiency?

Is this Cal/Mag deficiency happening?The taller of the 2 Strawberry Bananas I think is showing some Cal/Mag deficiency so I added 1tsp per gallon when watering. There is only seven leaves exhibiting this on the plant and no other plants have this and everything has been the same for all plants so curious whats up?
