does the leaf feel leathery? It was probably under watered or over watered at one point and the ph was slightly off. Nothing to worry about if it's just the bottom fan leaf. Just re adjust next time and you will be fine.

I wanted to ask if you think this plant has mold or if it's just a major deficiency due to a blockage. I have an indoor plant next door with some plants growing with dark spots, it's in my previous question. Sorry for giving more information, I don't know what would help.

Hey everyone, I've had these brown spots on the old leaves of my little plants for a few days now. In the weeks before, I fertilized, but only with 1 ml of BioGrow, 1 ml of BioBloom & 2 ml of CalMag from BioBizz — I think it's more of a deficiency. Thanks a lot for your tips!

Browning of leaves, heat burn or pests?
Plants are showing signs of browning, and other weirds leaf markings, kind of grey-ish not too pronounced. It's been very hot and sunny here for 5 days, temps reaching above 37°. I left them in the sun during this period, is it heat stress? Otherwise growing nicely.

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...

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

Should I start fertilizing or monitor the pH?
Hi, I'm a beginner, about 10 days after switch, my lower and slightly higher leaves started showing signs of damage. I grow them in a greenhouse in strong sunlight, but I think that they don't get burned, I haven't fertilized them even once. What do you think of this?
