What are these tiny white dots from?
Do you think I have spider mites? I don’t think it’s moldy mildew. I have no idea where I could have gotten them from though.

Yellow tips on most leaves. 1 gallon yesterday, no nutes (every other water) at a ph of 6.5. just did her stretch. Otherwise, looks good and healthy. Lifted the lights up just in case, but I want to stay ahead of this. Any thoughts or recommendations?

One of my 3 plants is significantly smaller than the other 2. Her leaves are multiple colours. She was late to shed her shell so I peeled it off myself. She is still steadily growing however I have been unable to diagnose her. The photos of her are labelled "sick one"

Why are my leaves closing up?
What is the most likely cause of my leaves closing up/folding? I've heard maybe calcium/magnesium deficiencies, or perhaps a watering issue?

How do I achieve the dark green leaves wedding cake wants? (More nitrogen?)
My plants are looking overall healthy but are not as dark green as I’ve seen most plants at this stage of growth, or like my plant on the bottom right of the canopy. I am feeding/foliar treating the same amounts to all plants. wondering what to do or should I just chill out?

Why are all the leaves on the upper half of the plant perky and the half way down start drooping off? Even the ones getting plenty of light. The soil is not that dry yet either.

Please help! What am I doing wrong? I’m a first time grower
My leaves were burning and now I know that I am burning it with nutrients cause my soil already got nutrients. I’m only using water now but now they are turning yellow and the big leaves have spotting. What’s the problem now and how can I fix it?
