If you're not ph your water you will run into lockout problems. It looks like lack of nitrogen but could be incorrect ph range issuse or over watering issue. 👍🌱

Nute Deficiency or New Leaves?!
Thoughts if this yellowing may be nute deficiency? Or are these just new leaves and I am concerned about nothing and I’m babying them since it’s my 1st grow? Both plants are about to be 2 weeks post sprout. Both are in 5 gallon fabric pots with layered soil (FFHF on top of FFOF)

Thoughts on my yellowing leaves? I'm currently thinking the compost I bought my be too nutrient rich, check the 9th week in my Afghan Pearl CBD. I obviously need to learn from any mistakes I inadvertently make.

Rate the Bud - 6 Week completed flowering
So this is my first time growing with using BioThrive grow, bloom, calmag bottle ferts. Would greatly appreciate any feedback on improvements, those 2-3 leaves with yellow spots seem concerning. On 'honest' scale of 1 to 10, how are my buds looking for week 6 in flowering?

Yellow spots on lower fan leaves
Hi Growers! First grow here and I am concerned about new yellow spots on my lower fan leaves (one tip is dark too). Soil is Atami Kilomix, heavily fertilized. 2 days ago only one leave was affected. What can it be? Mg deficiency? N deficiency? Too less water (100ml every 3days)?

Deficiency because she starts to flower? Leaf tipps light green. Some purple at the stems.
I have not fed her, just a bit here and there. So I do believe she starts to need her medication. Its going to the end of preflower week1. Symptoms: some light tipps and some purple at the stems. Solution: feed her P and K. could add some CalMag ? Or Still feed more NPK?

Tuve exceso de N al comienzo de floración, le hice lavado de raíces y continue aplicando fertilizantes de manera regular, hoy esta así. Mucho olor a verde pero no de floración, hojas con necrosis, estoy en etapa final de floración y sigue vegetando con hojas en buen estado!
