you need more potassium in your diet, my lady! adjust the ph at 6.5 before adding anything (any npk solution will be appreciated) happy harvest!

Any suggestions why they are like this? Maybe a lack of drenage on pots or a over water schedule...

Stains on the plant
Hey guys, first of all, thank you for taking the time to read this. I started growing my first canopy and since I am little excited, I started before everything I ordered arrived. For that reason, I am still using the soil I used while planting the seed. Did I fuck up already?

Nutrient problem flowering
Hey everyone, wondering if you can all help me identify this nutrient problem? Believe I over did Nigrogen a while ago, and that’s fixed now, but what are these markings? Should I add more bloom nutes? All info in my diary. Thanks everyone

Brown spots and holes
Had snails and aphids earlier, but knocked them out. I'm these brown spots / holes in my girl. Don't think they're the snails and don't see any bugs.... been rainy and fairly cool, 60-70F. PH is currently high at 6.9. Any thoughts or recommendations for a mostly clueless newbie?

What is happening here..
I am confident the spots are Cal/Mag and Manganese deficiencies. My unorthodox flushing technique failed Live and learn. Please let me know your opinion.

dark, curled downwards and brown fan leaves
Why are the fan leaves dark, curled downwards and showing brown marks originating from the edges? Had an issue of dark and curled leaves for a week or 2, did think it was getting better (N2 deficiency) but now suddenly after not watering for a day the leaves are going brown.

should I be concerned about this hole on my leaf?
hole showed up today. wondering if this looks like a pest did it or if its something that just happens from time to time. I read that holes can appear in leaves when there isn't enough potassium, but I'm feeding with molasses so that shouldn't be an issue.
