How Often Do I Flush my Plants?

hello, i want to know how often i should flush my plants?

i know you are suppose to flush 2 weeks before harvest but. also heard you should flush every two weeks trhoughtout its whole life to clear old nutes and salt build up.

is this really neccessary? btw i am growing in soil.

thanks community

Unless you seriously overdo it with the nutes, flushing is not necessary.

I would also appreciate any feed back on flushing during the grow. Is this a good idea? I have read this good post on the final flush https://www.rollitup.org/general-marijuana-growing/2176-how-flush-soil.html but not seeing much on flushes during a grow and had heard that folks that grow non-organic can benifut from flushing (monthly? , every other month?) during the grow to remove salt build up.
Thanks in advance for your respones!

totally agree with wet dog on this, unless you get serious lock out due to ph issues, i would never flush. it can cause nothing but problems when you are a new grower. people tell others on here to easily to flush but i always leave it to the last course of action. a lot of people flush to clear out the salts and excess nitro n crap in the soil 2 weeks b4 finishing flowering, but theres even debate whether thats needed now, i personally dont and theres no difference in the taste of the bud. i grow with bio by the way.

I also like to know about how often that i can flush my potting...because i have serious problem with ph....always over 7.5 or 8.0 ph...last two weeks, i decided to flushed with pure water a lot because my plants(veg stage and 1 month old already) are stunted and wont grow, and leaf started curl down...i thought it was bad MG soil (nasty chemcial?) so in the few days it looks good once again...so it started pale on leaves i guess its time to feed my plant a all purpose food, then one week later , it started again like old pattern high ph, brown spot are back, curl down, and this time lower the small leave started yellow and fell off...today i started to flush till runoff water is clear and last thing i put 1 tsps and half strenght water, it seems like i have to flush every one week? i dont know if its good idea but its all good for me becuz im still learning from my trial and error that will help me better grower in the future

cheer, happy growing.
