Ph or not to Ph that is the question

Hi thanks for taking the time to read this so my question is when flushing do i ph the water or just use it straight from the tap any help would be appreciated

Be prepared for comments from all sides ... There is tons of threads on this.

Tap been doing this for very long time works great think no more about it

So this is my first grow and i have managed to get to week 8 with minimal problems i just don't want to get any further then go to flush and do it wrong and f**k the full thing up i know its either i do ph or i don't sounds simple but i have read a few different things and still unsure as to which is the best option I'm growing in coco and been using canna coco a&b with buddhas tree advance meta boost and buddhas tree pk 9-18 been using ph 5.8 water

Are you talking about flush before harvest and your growing in dirt if so I believe a lot of guys slow down on nutes & water the last couple day and yes ph

Yes its a flush before harvest I'm growing in coco coir i have been advised by a friend to flush for 5 days but then i have seen videos saying upto two weeks flush is ideal i literally have no idea everyone says different

I'm hydro I only shoot for 3-4 days helps when plants are drinking well,meaning if you bud to long plants tend to drink less

It sounds like you are using plain water to flush. No bueno. Though it may seem odd, you want some nutes in your water to flush

i leave my tap water out 24 hours to clear it out and it seems to work good

I know a guy that swears by pouring boiling water over his rockwool NFT at harvest. Can't say I understand why.

I bought a $20 ph water tester probe. You're damn right I ph. I didn't buy it to just sit there.

I don't flush, I've tried both flushing ph'd, Flushing with flushnutes, and just watering the last 14 days, honestly none that i've asked has ever noticed a difference so i just went fuck it, i believe my plants need their nutrients to fully develop and dense up at the end Cannabis is about finding your own style that fits your plant.

If i had to flush i would go the ph'd way just because i have everything needed and it cant hurt i grow in soil.

I believe this comes from old school growers and hippies believing it kills the root and instantly starts fermentation/curing in the leaves and buds and should result in a 30 day cure in just 3 days i think it is?

Following this from Interest... and arguments haha

I grow in peat, my dusty ph pen is on the same shelf as my unused bottled nutrients

Use RO water and you'll never have a need to PH it regardless of what you do with it.

Is that ONLY with that "Hospital Grade " RO you claim to have?
Don't "Flush," Just reduce your TDS over the last weeks. Finish in the 100's.

It's surgical grade, dipshit. And no. Any good RO water will always be 6.5 on the nose every single time.

do you find it troublesome to pH? why wouldn't you its real easy and cheap? just saying it can't hurt to pH.
I don't flush my plants cause well I never seen any benefit to it, I always grew semi-organic and now full organic so I don't have chemicals to flush out anyway. never flushed any veggie plant or herbs or anything, I figure nature doesn't bother so why would I.

Having to PH your water means that there are impurities, chemicals, and who knows what else in it that make the PH unsuitable for use. PHing your water does not remove all of the harmful contaminates that were in it to begin with. It simply changes the acidity level by either adding acid or base to it.

The point isn't that it's hard, troublesome or expensive. The point is that you're essentially doctoring up shitty water to use in your grow rather than using quality water and not having to bother with it.

What's more, the shitty PH'd water can still cause all kinds of issues due to whatever contaminate it was that made you have to PH it to begin with. Many people run up against that and all you hear from people are PH it and Nutrients.

Shitty water is shitty water. If you're having to PH it, it's shitty. Best to use good water from the get go and you remove 99% of every problem you will ever encounter in a grow.
