Gorilla Bomb, outdoor grow, directly in soil, Miracle Gro 20-20-20 once per week. In the past few days, leaves have developed brown to black spots that start at edges and spread inward. I have 1 Green Crack under identical conditions and another GB and GC in outdoor pots

You got some yellowing and leaf crawling too. Cut back on that gro, go light on it. Just water them for a week, there in soil so you’ll be fine. I would also start ph balancing your water, go easy on that gro. Good luck.

I've got 3 other plants under the same conditions that are the picture of health, wouldn't they also show similar leaf damage if it's a nutrient imbalance?

That's a pH balance problem 100%. The soil it's in needs to be adjusted. Start ph balancing your water to 6.2 for every feeding or watering.

Nutrition inbalance. Vegging requires a ratio of 3-1-2 npk. Flowering is 1-2-3 ratio. Probably has the soil ph out of alignment too. Would be worth looking into as well

Brown spots on leavesWhat seems to be the problem with my plant? The old leaves get brown spots whereas the newer ones have yellow edges. Is it a pH issue?
Is there a fix to this?
I grow in soil and the plant is 4-5 weeks old.

Braune Flecken an den BlätternHallo zusammen,
Ich habe seit ein paar Tagen diese braunen Flecken auf den alten Blättern meiner Pflänzchen. Die Wochen zuvor habe ich gedüngt, allerdings nur mit 1 ml BioGrow, 1 ml BioBloom & 2 ml CalMag von BioBizz — denke eher es ist ein Mangel.
Vielen Dank für eure tips!

Phosphorus def in veg?Phosphorus deficiency in wk 4 of veg? I noticed a few small discolored blotches on lower leaves 2 days ago and today it is a lot worse! Use flora trio, and 2 other plants in this run are under same conditions with same nutes. Could this be a pH issue? PH has been consistently ~6.

Are those nutrient defficiencies? Which ones?A plant had interveinal chlorosis on new leaves and then proceeded to show brown patches between veins on middle leaves. Another has coppery brown spots on leaf edges on the middle of the plant. Both were rootbound in living soil (peat/perlite/hummus + ammendments).

Dry brittle leavesDiscoloured older leaves curling up at the edges and turning dry and brittle. I think my problem is over or under watering. I've been very careful to avoid overwatering so I'm leaning towards the latter but what I've read online suggests dry/brittle means overwatering. Thoughts?

DeficienciesHey guys,
First two pictures are from one plant and the third is from another.
Any idea what the issues are?
First two pics I’m thinking phosphorous? The markings are only in one section though.
Second I’m thinking cal mag?
Thanks everyone

Potential bud rot?My critical cure has some of the smaller leaves near and in the buds which are starting to turn rusty brown. Is this a starting sign of bud rot? Should I cut them early?
I do not see anything abnormal under the microscope or when separating the large buds by hand. Thanks!
