Weird leaf problems are usually pH related, check it and adjust to the correct level. The tiny spots might be bug relaterd too, not unusual in outdoor growing.

Hello @RealOAK5. That is a calcium deficiency.I also see something that could be a manganese deficiency or spider mites.Have you checked the plant for bugs and what soil you use? If the soil you are using is the soil that was already existing to your garden it is very very possible that is lucking calcium and other micro nutrients especially if you have used it in the past, either for cannabis or any other plant. If that's the case then you have to add a cal/mag product. If the problem was the PH then you should also have had a magnesium deficiency too as these to tend to lock out at the same range of PH. I also don't think the depth has nothing to do. I have seen huge outdoor plants growing at depth of 50cm. Roots can also develop horizontally. Also next time you should consider to use a more balanced fertilizer. Happy growing ! :facepunch:

hey there! i have tthe same thing happening on my outdoor plant too. basically its just the normal things that happen when you have an outdoor plant. Just be super careful outdoor with bugs, check especially under the leaves for signs of pest. get up in there on the flowers to make sure the bud lice don t make a home in there. i see you're using kelp; that's cool i do too, but the thing is it changes your PH, so what happens is every time you add that the PH is off which can cause fluctuations and cause the same sort of symptoms that you're seeing. Dial in that PH and you wont see any new leaves being effected.

Hi @RealOAK5! This could be: 1/ Roots related issue: root-bound, root-rot. 2/ Calcium deficiency. 3/ Manganese deficiency. The last two options could come from a wrong pH, are you applying the optimal pH range for your plants (6.0~6.5)? This can also come from a nutrient-lockout / salt-buildup. Do you check the EC of your feedings? How often do you feed and how often do you give plain pH'd water? Now for the 1st option about roots, is your garden deep enough for roots to spread? Do you have a concrete slab under the medium, if so at what depth? Let's investigate all together and I'm confident we will find a solution. Happy growing :facepunch:

Hi RealOAK5 , I see no big trouble on your plant that could harm your plant bad in that stage of Flowering. But i got one question to your fertiliser =? did you make a typing mistake or is it9-58-10 for real?
In that stage the plant need P*k and less Nitrogen. I would recommend you to buy any Blooming fertiliser. Or do a compost tea with more P and K. I will let you a link for selfdiagnosis in the comments. But its hard to say anything with so few datas.... Happy growing and happy first harvest soon

Have you gotten yourself a joulers loupe yet? Thats maginfide for looking at trichromes? If so use whatever magnifying glass you have and look at the dots, you should see any bug holes in the buds or if the spots appear to be moving etc. If not then try looking up nutrient toxicity/deficiency photos online. Theres some great info and diagrams to compare your leaves to.
Happy healthy growing to you. I :v:
