Nutrient issue?

Hi there! I'm about 6/7 weeks into flowering and I'm noticing a lot of my top leaves are turning yellow. Also. This is a blackberry kush strain, is it normal for leaves to turn this black/purplelish color (I know that sounds like a stupid question, but I'm genuinely asking)?

Ultimately I'm just wondering if I'm having a nutrient issue because of the top leaves turning yellows. I do think I burnt the tops one day that I forgot to turn my air ventilation back on. Either that or a lack in nutrients. Any help is welcomed. I'm an open mind/book!

Hi Erick,
I think that's strain related coloration. That alternating striped pattern on the leaves is cool looking. I have seen that in other plants. Have seen it be misdiagnosed as MG deficiency but I would totally not suggest that on your plant.

I am looking forward to seeing more pictures as it grows.

At this point 7weeks into flowering they do have nutrient burn . At 7weeks into flowering you should not be feeding them any more nutrients . They should be getting plain pH water . Unfortunately it looks like the excess of nutrients is touching the buds and you can see the leaves yellowing is all the way back to the buds. But don't do anymore feeding and next time you water just give them a real good watering and then oh water from this day forward . Maybe a light feeding of sledgehammer won't hurt . But they aren't burned bad

. Flush product now would be fine, but if a little burned, you could have some flower delay. I think you can still pack on some buddage. watch the trichomes.
