Your either lacking magnesium or have excess phosphorus/potassium. So either cut back on the bloom nutrients or add a cal-mag supplement to her diet.

Its a PH fluctuation/issue ,which prevents from absorbing certain nutes in this case magnesium ,give her more calmag soon and check ph. Or give her epsom like

Wieso rostet sie?
Hey, I know that in the final weeks of flowering, the leaves can turn yellow, but it looks like they're rusting. I've done some research online, but I would still like a personalized answer if anyone feels like responding. It's my first plant!

yellow/copper appearance in some leaves after first run off watering
hi! after the first run off watering the girls seemed alright, sturdy and firm but some of the leaves (one leaf, 3 plants currently) experienced copper/yellow/orange tints . this is only on old leaves so looks like mobile nutrients. could this be cal-mag issues?

Leaves are turning yellow!
One of my plants began turning yellow. The leaves still feel like leaves but just yellow. It's currently in flower and I am using the two part nutrients of Maxigro and Maxibloom with maxibloom currently cause it's in flower. I am pretty sure it is nitrogen deficiency. Help?

First leaves died. Overwatering?
The first real leaves died from the tips. My theory is that this was caused by overwatering. Does that sound plausible? Feel free to check the diary for details (it's my first one). Thanks!

2 Yellowing Fan Leaves
I have 2 large fan leaves from the main cola turning yellow and 1 almost looks crisp or burnt on the edges. It is only 2 of the leaves and by my reckoning, they are 2 of the oldest leaves on the plant. From research, it could be the bump in nutes or water issue. Any ideas?
