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.

Super Yellow Leaves in Mid/Late Flower
Does this bottom left plant need more nitrogen? The last two waterings we've given it 1.5 ml/liter of Micro. Should we give it more? The other 3 plants of the same strain are much smaller, much darker green, and further ahead in flower. These Blue Dream autos are 51 days old.

Fan leaf deficiencies during flower. To cut or not to cut?
Day 85 Update: G13 has a ton of fan leaves turning fast. Pretty sure it's a PH issue. Should I wait until they're dead to trim them off or get rid of every fan leaf that is affected more than 50 percent of the leaf?

Yellow Leaves Normal?
Hi Everyone! I’m just starting week 7 with my RQS fat bananas and northern light. All autos. RQS state harvest in 9-10 weeks. All the girls have 3-6 low level fan leaves going very yellow. I assume this is fine but I’d love some feedback. It’s my first grow.

Yellowing
Hi! It looks like my grandaddy purple is starting to yellow, in my last week of veg (7). Could it be caused by too small of a pot (3gallons), this is my 4th grow, first time growing only one plant using scrog. Maybe an upgraded pot before I flower? Thanks!

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?
