Flushing perlite

[Guest]

Hello every1,How long do i need to flush perlite for if using 15 litre pots/Perlite?If i give a good flush the last 3-4 days will there still be traces of chemicals/Nutes?Ive been using Manutec 2 part hydroponic nutrient and Nutriboost,I will be flushing with ph adjusted rain water is this ok?Thanks

I would quit the nutriboost, it doesnt need it. does it? I use it only up to flowering then stop it, Have you noticed much differene in using it through flowering?

 

I reakon it would probably take you 2 weeks? In my flood and drain with clay balls it flsuhes in about 6 days but I always (try) to leave mine for 2 weeks.

 

If its relevent to perlite you could use a product like Final rinse or FInal flush to speed up the process.

Thanks Ferenge420,The Nutriboost has been outstanding so far,I will flush for 2 weeks if need be,Do you mean use ph adjusted water instead of nutes or a good flush everyday,Thanks

If you flush for 2 weeks will the plants still be getting slight nutrient as i dont want all the leaves to turn yellow and die off as i have seen b4 but want as much chemicals removed as possible,Thanks again

Flushing is only needed for 5 days so all the chemicals will be well flushed after 2 weeks.

If you have a Sativa dominant the leaves are usually going to turn yellow an the plants will look pretty ugly in the late flowering stage, that's just the way it is.

Final flush etc, provides a minimal enough of nutrients to allow the plant to use up all its chemical stores etc(flush) but keep the plant alive to stop it from going yellow.

 

but a few yellow leaves are both ok and perfectly normal, you normally cut these off your bud anyways.
