Cannabis sativa from the looks of it 🤭. Plant looks fine. It's in flowering and using up nutrients. Be sure to water properly and give enough potassium and phosphorus.

¿Que puede ser?
Hey. My question is why the larger fan leaves are turning yellow, this is in mother soil and in the flowering stage. I water every 2 days, I think it might be some deficiency or watering issues. Can someone help me?

Leaves turning yellow/pointing up, stem turning purple
Having a problem with one of them.. all the leaves have gone very yellow and are pointing upwards. The stem is also very purple now. Any ideas what this could be? Other than a feeding of bud candy and watering here and there it hasn’t gotten any other feeding. Thanks!

What nutrient deficiency is this?
What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.

Rapid, uniform, wide-spread leaf yellowing - flowering week 5
Entering week 5 of flowering on this photoperiod and she's experiencing wide-spread yellowing in leaves over past week. Haven't been monitoring pH or PPM, but am assuming this is nitrogen deficiency due to nutrient lockout. Can anyone confirm or recommend treatment beyond flush

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?

Auto flower deficiency
Hello I have a auto flower I grew in soil from last year. I believe this is a nitrogen deficiency but not sure. This plant is 37 days old and 1 week into flower. How can I fix this? Cal-mag? Worm poo? I'm not sure.
