sign of nutrient burn

[smokeOnE702]

hi my plants r starting to have lil burn tip on the leaf. how would i get rid of that by flushing right ? how many days do i flush it for and im using sink water and the ph is at 7.0 do i still needa balance it to 5.8 for the flush ?

flush with 2-3 times the volume of the pots worth of water (1 gallon pot 2 gallons water).
Also the damage done cannot be undone, but will prevent further damage.

no need to flush just back nutes off a lil and you be golden :thumbsup:
Flushing will only add time and effort, as already stated you can not undo what is already done. If you are topping off your res during the week with plain PH'd water and draining and refilling your res weekly then continue on with topoff during week and minor sdjust nutes on refill.
Problem solved ..... next :jointsmile:
