Final Flush, Ph Water or Not?

[axl]

I cant find anybody who says with any certainty either way. I do find its nearly impossible to keep the ph stable when its only water, so if i dont have to ph it every 3 hours i would be happy.

So, im talking the final week of my grow in hydro, used floraklean for 4 days to remove the salts, now im runnin plain water for a week. SHould i ph it or not?

First off you dont need to be monitoring your ph as much as u are. I just measure it once every time i fill up my rez or every three days. definitely not every 3 hours. but ya i would ph balance the water. i mean it doesnt really matter because its not like u should be worried about nute lock out or anything but i mean might as well.

If your having to PH every three hours and adjust the ph something wrong! goig to need more info on what your doing! pics to

you don't need to PH adjust, and you also don't need to flush either…

I did the same as you I flushed with Flora Kleen for 7 days then another 7 days with just straight PH R/O water ..

If you dont flush you will have what they call " fire works" every time you light a bowl ... ( little sparks ) you also wont have the gray ash ..

I used this theory as well lol... "Might as well "

I didnt reasd everything others posted but If you dont flush expect your buds to taste like nutes and not buds theu way they should taste . At the end of my plants life cycle I flush 3 full days 3 feedings a day just pure water. Make sure your ph is always set I check at the end of the day. Dont listen to anyone that tells you otherwise. P.h. down is 11 bucks for a 9 month supply and I use it every day who cares its cheap enough.

I grow in hydro and I fed the girls right up until the night before harvest. You don't need to do a final flush. No sparking or wierd/bad taste. I have 15 ozs of some braggable buds from my last harvest to back me up. I'll put up my sweet Blueberry against anybody's. I will never do a final flush again.

I grow in DWC. I usually use flora kleen for 3 days then switch to RO for a week. Never ph'd the RO water and never had any problems. My thinking is that you PH the water so that the plant can take up nutrients properly, but during a flush you're trying to get the girls to use up the nutrients they already have stored up not take up more from the water. Not to mention, it's RO water, so there shouldn't be anything in it to take up anyways.

No matter what you choose to do, know that the "to flush or not to flush" debate tends to get very heated, as most growers are very passionate about what they do. You're going to get a LOT of contradicting information asking these questions, and NONE of it is necessarily wrong. Flushing is just one of those things that you gotta try a few different ways and see what works for you.

I have always been told to flush, and it is strongly recommended by GH. I have them on speed dial, their techs are really helpful. but anyways I can deff see your point jointproject, but you could also argue for the plant to completely take up the nutes that is hasnt used yet it will need water that wont lock them out of the plant. i dont really no the science on that one, and with everything im sure someone will have a competely different opinion. Just, might as well do it.

Good point Autumnfalls. I hadn't thought of it that way. +rep for insight

i always flush. i flush with sledge hammer from fox farm for about a hr and then regular water phd 5.8 for 1-2 weeks. My stuff tastes good.

lol so we all agree not to listen to any thing this guy says.... and yea need a lil more info on your grow to no why tthe ph moving so much but a quick fix i would say is if its g oing down when u adjust it leave it a lil high if its going down then adjust it a lil high i would only do this once every 24hrs

 

[drgreentm]

the point of flushing is to force the plant to leach itself of all reserve nute's it has stored up in itself now a plant can have over two weeks of reserve nutes stored away so if you are not flushing for at least two weeks your plant still has nutes in it plain and simple. i dont see a major need for it but thats my personal opinion (done side by side comparison couldnt tell the diff) but anyway if the point is for the plant to not take up nutes from the roots why would you need to ph anything ph is just for the plants ability to take in nutes so if your PHing when your trying to leach thats just a double negative lol no need for ph. your basically just using the water to keep the roots hydrated so they dont wither away and kill the plant in 2 days. i never ph'd water in a flush you have no nutes in the water anyway your just wasting your ph up/down.

Care to explain your reasoning behind this? I prefer my bowls end in ash, not embers. I also like it when my buds don't snap, crackle and pop when you light them. I also prefer my smoke not be harsh on the throat. You are correct, you 'don't need to' flush, however you should.

The plant is still going to carry on biosynthetic cell operations even after we stop feeding it. To do so, it needs water and nutrients that it will pull from other parts of the plant. I'm thinking the water should still be PH'ed in this stage to prevent any nutrient blockages within the cells.

I don't know if this contributes, but my RO water has a pH of 6.5. Also with my nex clone grow Im going to use hempy and not flush one or two to see what happens. SOG comes first though.
