Bugger, then don't waste any more money on it bruv... Sohum goes to the end with just water and pk in 15litre with an auto. Organic is all about creating and maintaining life inside the soil... So every bit of water out the bottom is microbiology in the bin... Changing from your liquid nutes must be a ball ache... You literally just keep the soil moist and alive without run off... My last big run went 12 weeks with 1 top dress at the start of flower....shes in 15 litres bro
Personally I would give up on organic with air pots they dry out too quick for organic... I ran 1 Air Pot last run amongst the last standard 11ltr pot run and it was crap compared to the Cheap sealed pots of the same mix..
All I can suggest is reammend with charge and water in with biosis to get some life kicking off
