Its suposedly normal at week 7, but it might be lack of nitrogen, it may even be one of the reasons why it is so small.

Check your runoff pH. It should be between 6.3 and 6.5. If it's far off do a flush. Problem solved.

New growth and top leaves have some discoloration. Could it be light related, or maybe a zinc deficiency?
She has been flowering for about a week now and showing some pale spots. At the start of flower I turned the light up from 200w to 300w. Light is currently at about 20" from the canopy. Plants seem healthy otherwise, should I be concerned?

What could be causing yellow leaves at the bottom of my plants. Deficiency? Are in soil that supposedly has weekly specific nutes baked in. Any help
Most plants in my grow are yellowing at the bottom. One plant in particular is showing what i would call severe stress. I think I figured out that I had an air flow issue causing plants to keel over that was easy to fix. The Bushy one is North shore Maui and the big one is GG.

Re:
Here's more pictures, and the top 3 inches of soil is dry to the touch before I water again usually. I must've messed up the past couple days or something. I did just add that Mars hydro ts600 though. Light stress?

Been flushing for the past week, the larger fan leaves are starting too turn yellow faster than I had anticipated but trich's haven't started turning amber yet. All the other sign's point towards her being about a week away from the chop but I'm a bit worried that I flushed early

Can anyone tell me what's going on in week 2? I transplanted and each plant seems to be yellowing on the lower leaves. Not very happy. Was dry when I took it out of the dixie cup and watered with 1/4 strength veg nutes and a root stimulator. It seems to be curling in as well.

Leaves browning in multiple spots Lower leaves yellowing but have green veins.
One plants leaves are browning in multiple locations. I attempted to diagnose the problem with runoff tests. pH was 6.5 and TDS was around 900ppm, which was expected since they received nutes that day. Despite not spreading to other nearby plants, could it be leaf septoria?

Anyone can suggest what kind of problem is on the photo - brighter inner parts of leaves. My idea would be that it needs more Magnesium?

Could this be light burn? Only on top new leafs. Have not fed her any nutes yet. I did lower the light after I did LST by the height difference after bending her lower. Have raised the light back up again but just wanted to check what people thought. Thanks in advance
