did your pot not have any holes to begin with? maybe that was all you needed.
it may be tightly packed but also could be a bad mix, which doesn't allow proper aeration to the roots. You could find another brand or add pearlite to it.
20 to 30% pearlite by volume should solve the problem.
not worth the extra stress if its moving along better now, just make sure to amend the soil better next time for future issues like those.
i know its hard watering soil sometimes, people always say the liff the pot method is the best but every soil comes different and has a different weight or consistancy which really throws me off for that method. plus as the plant grow more weight is added on which throws that off also.
if you can poke the bottom of your pots to feel how dry or wet the soil is, thats the best bet to water correctly ive found is to wait until the bottom is somewhat dry. its better to underwater your plants than over water them, they will show sings of being hungry way faster than cell damage from over watering, which they can appear healthy for a while but will slowly start to deteriorate.
it's better if pearlite is spread evenly in the soil (at least you know this for next time), but now it's too late. if you feel they will not grow good this way, you could put some pearlite in the bottom of a new pot that is slightly bigger and then try to take down any loose soil off the roots without damaging the roots and repot in the new pot with extra soil needed beeing let's say 50% pearlite.
works just if you can fit bigger pots where are you growing them..
good luck!
i havent worked with soil just soiless well besides hydro maybe its different. with soilless the lift the pot method seems easy after a while because the pots feel abnormally light to lift after lifting them a few times you should be able to feel the difference its like night and day. with that being said im assuming that soil must always feel kinda heavy? is that the case? best of luck id say if they look like there on deaths door replant if not ride it out and change your mix ratio next time best of luck hope it all works out for ya.
how far along are you? i mean you can gently repot with a bed of hydrotron perlite or somethin in the bottom to keep the water draining down off the roots some
