My leaves are getting yellow from the bottom, and some have burnt tips. It started when she is in flower. I often feed Powder Feeding from Green House. PK+ (NPK: 0-30-27) and Hybrids (NPK: 15-7-22) the PH is 6.5 They say this strain wont need much nutrients but can handle more

Brown tips on older leafs
What indicates the brown tip of a single lower leaf. Growth is also relatively slow. I see this on my 25 days old Hulkberry Auto. The plant sits in a greenhouse on my balcony. Night temperatures go down to 8-12°C. No fertilizer used.

Anyone know what's wrong with my girl?
Can anyone tell me if this is going to effect my flowers? Should I cut these leaves out? What can I do to correct it? I left a pretty good description in week 7 of the battle with this plant.

Why is One growing perfect the other is struggling
Why is one of them doing so well growing better deep green leaves and the other is at least 2 inch shorter and leaves are yellowish. I’ve been feeding them both the same I’ve missed the shoter one of the soil is still damp. I’m guessing nutrient over load so thinking do a flush

Burning tips
Hi, I notice the some burning on the tips, I think it is related to nitrogen toxicity, it started happening during early flowering, I have been adding cal/mag & b52 and they also contains more nitrogen. I have been topping just plain water for the last week.Anyone had this issue?

Upward curling leafs, burned tips, 2nd week of flower
So I'm two weeks into flower now and my leaves are getting burned tips (I'm guessing nitrogen deficiency due to the light green of the leaves or some lock out) leafs are also curling upwards :/. And some fading on some lower leafs. Using biobizz roughly 10ml each Any ideas
