Spotted leaves, Burnt tips, New grower please help!Any ideas on what could be causing the issues on my leaves where there is spotting and burnt tips? I've been watching the pH and keeping it within what I was told is vegging, but the issue still seems to be happening. Do my roots look okay? Really at a loss at what it could be.3y ago

Under-watering? I water all my plants equally and one seems to be growing steadily and two have stopped. How often should I be watering in smart pots and how much water should I be using each time?
Also is there anyway to save my two heat damaged plants or should I scrap them?Week 3

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 ✊Week 9

Is this due to the sun and hot weather?Some parts of some leaves are looking like they're burnt or something.
Is this due to the sun? Or do I have another problem?
It has been extremely hot last week (around 35 degrees all week). And the plant has been in direct sunlight (I've moved it into the shade yesterday)5y ago

Hi fellow growers, I need your opinion on one of my plants. The plant on the bottom left has really skinny leaves, they seem to be also a little bit darker than other plants. I added one photo with marked leaves for comparison. I wasn't able to find the answer on web :/Week 6
