Flushing plants

Hi,

What is the best way to go about this? I use Clearex right now. Should I water until I get the ppm close to 0 and then water half strength next time?

Nope, just use the clearex per the instructions. 10 days before harvest just flush with plain water and clearex. 3 times the volume of the pot its in, so if its a 3 gallon pot pour approx 9 gallons of clearex/water solution and let it soak through and pour out the bottom. The next time it needs water just do the clearex water flush again and then you can use just plain water if you need any more.

Do you only do it 10 days before harvest or throughout the flowering cycle? I'm watering with ppm of 1500 and they are coming out well over 2000 which tells me they need to get flushed. What do you think?
