Deficiencias en automáticas

Frm11001started grow question 5y ago

I'm in the 4th week of flowering for my autoflowering plants, and besides having nitrogen deficiency in several plants, this happened to one of them two days ago and is spreading quickly among all the leaves in the middle of the plant. I thought I was fertilizing them correctly, help!

Hi mate, I believe you are suffering from a couple of issues. One is PH whch is causing part of your problems. The other is lack of oxygen in the root zone. Best way to imporove this is to make sure your water going in is below 72'F and above 65'F. Also, 3%hydrogen peroxide will add oxygen to your substrate. As well as passing water between jugs will oxygenate the water. Good luck and happy growing.

Please see the 2 photos marked in the diary. Is this a classic PK burn? Did a feed with no MegaCrop, no cal-mag, just PK boost at diluted dosage. The coppering and yellowing has come sudden. Leaves are crispy where burnt. I hear its easy to burn with PK boost. Did I do that?

Black marks on leaves of a slow grower.Noticed there's black markings on the edges of the leaves on our slowest growing plant. My initial thought was water droplets sitting on it before it had fully broken out or could it be something else?

Brown/Grey spots on the leaves Hey, I hope this is my last question for this grow :P I've noticed some brown/grey spots on the yellowing leaves, what could they be, deficiencies or sunburn? I'm still feeding the plant with nutes, but the next watering will be a flush, so I didn't expect discoloring before that

Black spots spreading // Need your help!Anyone got a clue what this dark spots could be? It started in a corner of the tent with 1 plant a few weeks ago and now it has spread to another. I suspect pH issues and a nutrient lockout bc of that. Not sure if its the same issue though..Could be an infection as well...
