Why did this happen? And is this normal?
most likely compacted it with the watering practices. start off in a solo and up pot if you want more success. the current feed water approach is not working and i'd suggest a change. i'm not surprised the media compacted.
to begin stop using biobizz all mix to start autos. it's too hot. photos can handle it but not autos. it describes itself as a heavily nuted media. not a good thing for new growers or autos.
use a neutral media with no nutes added. especially if you want success with tricky autos. it will help teach to feed them from the get to. it's easier when there is nothing in the media and they depend on you.
i'd also stop growing autos if you wanna make stuff piles and piles easier. autos are super finicky and can be simple to fuck up. they will keel over when not happy and you lose the plant. photos you can get back to health without stunting or killing.
