Black spots?

MarkWatneystarted grow question 4 years ago

Is this a deficiency, nutrient burn, or disease, growing in MG soil, recovering from overwatering as well.

Definitely not deficient at this stage in the game, the soil could be a little hot for it but first id check the ph of soil and make sure youre checking ph of your water too, it should be around 6.2 for soil. It really looks like the soil may have compacted and the roots may not be getting much air. Roots need oxygen to live and to keep things like root rot to a minimum. Hope this helps some, good luck!

Browning leaves sections of leaf surface discoloured Day 18 leaf worries, browning areas, slightly metallic shine. I think from reading it might possibly be a phosphorus deficiency but I’m not certain so though I’d ask for advice. Thank you for your time and all answers are appreciated. Have a great day!
