Why do my sativas always end up like this?

[william76]

Sats normaly need less nitrogen,when feeding a mix of sats and indicas I feed the indicas then I dilute the feed slightly with some water for fussy sats,works a treat.76

I cut calmag after stretch and they are doing somewhat better. I'm still getting a slight mag deficiency tho. I might cut the calmag all together in flower and just use gypsum and epsom so I can get the ratios right.

I'd be pulling those big old fan leaves off. To me it looks like those leaves are having a small transpiration issue. Watering? Good air movement through the plant? Humidity? Temp?

My temp hovers between 75 and 80°F
My humidity jumps above 60% at night even with a dehumidifier in the tent and then stays below 50% during the day.
Automatic watering 2x a day until runoff in 100% coco
It's only this plant that does it, my other strains do fine.
