You can, human urine is high in nitrogen. Use a mid-late day. Dilute it 60:1 water. Sounds gross, but if the human it comes from is healthy then it will not contain anything bad.

They look fine to me - but perhaps that's just the photos... A magnesium deficiency will affect the lower leaves first turning the tips yellow which then moves towards the stem... as the yellowing moves towards the stem, the tips become brown and brittle. If this is what you're seeing, the first place I would look would be to your PH readings... these should be in a range between 6.0 and 6.5 (in flower, I like to get to 6.2 as more micronutrients are absorbed at that level). Your diary doesn't indicate a PH for this grow which makes me think you don't have a PH pen... this is an INVALUABLE tool for anyone growing cannabis and I would urge you to invest in one.... they can help you avoid a myriad of problems...
Good luck!

Stunted leavesOne of my plants is having a hard time - it's technically growing as fast as the others but it's leaves are half the size, slight discolouration and cupping. I suspect Mg, PH or overwatering may be the issue. All variables for each plant are exactly the same.

Yellow and skinny growth?Can anyone tell me whats going wrong here? I'm guessing the tips yellowing is nutrient burn from the MG soil. But the allover yellowing between the veins and skinny growth has me stumped. My first grow did something similar going into flower. I appreciate any tips or suggestions.Week 5

Seedling getting too much light?Is my 6cm tall seedling getting too much light? I downloaded a luxmeter app and for front/back cameras, it reads 4000-6000 lux. I'm worried about the light green veins. Is this normal? First grow so super unsure what everything is supposed to look like. Light is 18cm from plant.

Leaves Showing yellow edges and bandingIs yellowing of leaves and dark leaves toxicity? no curling . moved the lights further away. I'm growing organic. The plants look stunted short dense. I've only got a cheap pH meter calibrated. 🤞 use RO water pH- citric acid. Overall they are short dense growth wise
