To Flush or not to Flush

My plants are into their second week of flowering and seem to be doing fine.

My question is to keep them nice and healthy should I be flushing them and if so how often?

Many thanks.

I think you're supposed to flush at the end, around two weeks before harvest. Right now, as I understand it, you're supposed to be giving them the right amount of nutes, heavier on the phosphorus than nitrogen.

Only flush if you have a problem.

That's what I thought. Thanks.

don't flush if nothings wrong. VH was correct, 2 weeks before harvest. some people do it a week before.

What is flushing?

spida have you ever sat down and read through the grow faq. suggest u do it.

It depends on what type of nutrients you're feeding them, what frequency and amount and the TDS of your irrigation water and when they were last repotted.

There's no hard and fast rules - if you get a build up of chemical based salts - you need to flush them - that doesn't necessarily mean putting through large quantities of water - it can simply mean watering them for a few times (on their usual watering schedule) with plain water and no nutrients. Plain watering will have a leaching and mild flushing affect on it's own.

At two weeks they should be fine, if you get problems with salt buildup it'll probably happen at week 4 onwards.
