Hello everyone,
I'm in 3rd week of flowering and I'm starting to stop browning tips on newer leaves. Any idea what it could be?
Thanks!

It is nutrient burn. See how it is just along the edges and the tips? If it continues the tips will start to curl as well and it will move further in on the leaf. It’s not terrible atm but I would easy up on the amount of feeding for now. Good luck

Leaf discoloration. 5 weeks oldI transplanted these girls 2 days ago and have started them on a new nutrition. I’ve noticed some discoloration on one of the leaves today almost sure it’s the nutrients. Can someone help me figure the best thing to feed my plants?

Yellow tips at bud-leafsWhat is the worst case of what could happen to the buds and the harvest due to the yellow tip burn?
Since 5 days the near leaf buds have yellow tips.
It could have any reason. Flys, high ph, to high nutients.

I’m seeing brown on the lower leaves. They also appear particularly shiny like a magnolia leaf. Is this too much iron or magnesium?Week 7

Magnesium or Nutrient Burn or?Magnesium deficiency, or nutrient burn or??? Only on the lower leaves so far, curling down was existing genetics - but the burnt tips are new and some have even curled up now. Probably 5+ weeks left so too early for natural dying off?Leaves. Tips - Burnt

More rusty spotsSee this now on more and more leaves. Only upper fan leaves that get good light exposure seem to be affected from this and also the clawing.
Have backed off the nutes completely for now and will add ground egg shells to the water in the hope its a Ca deficiency.5y ago
