High humidity for long periods on root zone, causing lack of oxigen, water less in quantity or frecuency till you find the sweet spot.

Leaves looking a bit discoloured and wilting slightly, what could be causing it?
Leaves are drooping a bit and slightly discoloured, especially when comparing it to the other plant. Also, a couple seem to be growing at a much slower rate, is this anything to worry about or will they catch up? TIA

Too much nitrogen/water?
I am having some trouble with a Sundae Driver phenotype. I have had this problem before and couldn't figure it out and thought I had corrected it with this grow by significantly reducing nutrients - currently on 3ml Canna A+B 1/3ml/l pk and 2 ml boost. Drinking 3-4l every 48hr

Do you think my plant is dying?
Do you think my plant is doing senescence or is it a problem with bugs or deficiency? If its senecence, do you think I need to stop feeding my plant and start flushing? I'm in 4-5 weeks of flowering and its an autoflower. Thanks

Yellowing and dropping of leaves
Does anyone have any ideas what could cause the yellow and dropping of leaves for the Royal Jack. All plants are treated the same. The growth is stagnating as a result.
