Im confused by so many different awnsers!! , plz i need to sort this problem out ???

[jaydee84]

Also, I do a maintenance flush every 1st of the month to flush-out all the built-up nutrients and salts. If you don't water to runoff, you should do the same. The stuff will build-up and can hit the plants like a ton of bricks.

this is a nice tip as i dont always let the water run my self .....DETOX.....thats what i need......
