Yellow leaves

[madmucka]

I'm growing stardawg. It's on day 48 of flower. They estimate around 63 days it flowers for. I have yellowing of the fan leaves. Should I be worried at this stage? I stopped canna base nutrients about a week ago and I am using pk13/14 and boost. Any advice would be appreciated. Thanks

That may just need the Nitro still in the feed. I still give a low dose of nitrogen in the bloom food. It's hard on the plant when it's flowering pushing energy towards bud formation it still needs some N is what i've found. Are you allowing them to dry and are you giving enough fluid?

Thank you for your advice. They are given 2L daily so I think they are not drying out. Can you buy a Nitrogen only nutrient? I'm growing in coco 60/40. I always follow the same feeding schedule maybe this strain needs more Nitrogen than others. I dont want it to affect the quantity, quality and taste of the final harvest. Thank you.
