Brown / Yellow / Rusty Spots

I_Love_Kushstarted grow question 3y ago

Hello Guys! Today I noticed a lot of brown / rusty spots on my plants sugar leaves, and I am wondering what it is and could be. I am concerned. These are clones of a CBD strain. PH always is 6.2

No diary = no information... but what it LOOKS like is a potassium deficiency... a good PK booster should fix her right up (but don't expect those leaves to look any better, they won't... but you shouldn't see the problems increasing after a couple of days). Good luck! And start a diary!

I also had something like that. It was a nitrogen deficiency in my case. Another possibility would be that the roots got too much oxygen or the substrate dries too quickly again? Try to position the fan a little higher.

Kalium-Mangel würde ich tippen. wobei am falschen Ph wert könnte es auch liegen Überfütterung eher nicht weil die restlichen Blätter keine zu dunkle Farbe haben

It looks like potassium deficiency or your substrate ph has changed on you.

Weak yellowing leaves Not every single time but quite often my plants are turning yellow in the middle of flowering. It starts from bottom and follows to top. I can basically “take off” leaves off stem and the upper ones getting dry and brittle. I’m also quite sure the ph level is correct. Any guess?
