most scotts pre-nuted soils are more acidic then cannabis would really prefer. You get slow growth rates, and a fair bit of
cal-mag deficiency through PH lockout.
I see a lot of bark and stick in the mix. You didnt use their garden soil did you? that's gotta be mixed about 50/50 with topsoil or its way to acidic with way to much time release feed in it, making the acidity even worse.
Your bottom leaves are showing bad calcium deficiency. I know that most scotts soilS haVE plenty of calcium in it. More then necessary for cannabis really.
If you are not using tap water you need to make sure the ph going in is between 6.5-7. If the PH coming out the drainage is a good bit lower then going in, you have a soil acidity problem, and the deficiencies presenting are actually a PH lockout. Trying to add more nutrient to fix these deficiencies if it's a lockout will actually compound your problem. If it's lockout and you correct the problem without a full ph adjusting flush before hand, your plants will go into overfeeding stress as soon as they come out of the lockout, and you'll be fighting another problem. Plant growing in a soil to acidic also tend to be growth stunted and grow quite slowly. With older growth perpetually displaying signs of late stage calcium deficiency
Having a plant in a container thats bigger then it needs like this also makes orrecting an acidic root
Id recommend letting the soil completely dry out over the next few days. And flush very thoroughly with PH neutral water. Then let fully dry out and watch for improvement. Making sure to test the runoff. Flush until runoff is more or less the same as the intake water, or at least within =/- 0.5. I probably wouldn;t have upotted that plant yet as small as it is either. Id probably have still had it in a solo cup. Having a soil zone bigger then necessary makes correcting root zone issues a lot more difficult, and it will be some time yet before that plant fills out that container enough to really affect the conditions of the soil in its own favor (which yes, to an extent, plants can absolutely do, some tweak their own root zone ecosystem constantly, my land race sativas did, and thats why i couldnt grow them in hydro, they treated my DWC buckets like a mineral rich soil and constantly secreted acids and byproducts into it, creating constant turmoil over PH)
You can get away with scotts and miracle grow fertilizers with cannabis if you really want to use them. They are fine and work well just require thorough flushing procedure before harvest. But scotts and miracle grow soils are terrible. I havent used one yet i would consider a good product. Theyre all very acidic, and have more time release feed then necessary, and they ALL, in my experience at least, require diluting with inert soil, the screening off of bark and sticks, or flushing and PH amending heavily before use with cannabis. They work fine for tomatos and pole beans in ground, but for cannabis in a container they can be very tricky. Their "garden topsoil" blend sits at like 5 ph unless you mix it with other soil, or HEAVILY flush it first. So does their "nature care" organic soil and pre nuted potting blends. None above 6ph, all way over nuted as well. All of them use osmocote as well. A highly acidic, high nitrogen time released capsule feed that continuously releases feed for up to 9 months, and is impossible to flush out fully within cannabis' life cycle too. Osmocote is really only truly suitable to slow growing, woody stemmed shrubs and trees tbh. Rose bushes and the such.
And just in case not aware, some people aren't, By purchasing products from scotts or miracle grow, you are directly supporting Monsanto as a business with your dollars and this may not be something you wish to do either.
