flushing????????

ok, so i've been having alot of problems and I think its been the ph of my water...finally got ph meter..water had been 8.2 ,,so now that i've got that corrected,,,I just watered a day ago...so soil is very wet,,,should I let it dry out before flushing? Is RO water ok to use? it says at dispensary that it removes salts...several kinds of filters...and some ion thing...also if using rain water do you have to adjust ph on that too?? WHAT IS BEST WATER TO USE?/ distilled,,ro,,,spring water (bottled)

bagseed,,,2 weeks into 12/12,,,,pics on my other posts...miracle grow soil,,,super bloom 12-55-6 ,,have not fed since flipping....300 actual watts cfl 2700k...fan blowing good breeze while lights on,,,,temps..80 daytime (lites on) 75 nite..(lites off) 2.5 gal. pots..good drainage..humidity is normally around 25% + / - 10%

I'd flush it just to make sure you have all the bad juju out of your soil. It's just a weed. It doesn't get purified water in the wild, and most tap waters should be about neutral +/- a little. I give mine tap, and rain water when I can get it.

same here .. rain wate if I can colect enough (rain water is neutral PH 7) it is no.1 in my oppinion and my plants love it (and would also be my choise for a flush)

tho one thing to remember .. in rain water you dont have any/many trace elements .. so need to add stuff like calium and magnesium if you only use rain water ..

beside that I use tap water (PH 7,6 and pretty clean here in Denmark) and I have no problems .. a good soil schould correct it by it self ..

so dont worry or do to mouch here .. your not in hydro .. just let here dry out and keep watering as usealy ..

and let em use up the Veg nuts and dont add more Nitrogen ..

when you water/flush make sure the water is room tempeture and water slowely ..

but tell me .. do they look helthy ? a few pics might help us help you ..

ok,,,so when i check runoff ph,,what should it be? if its too high do i lower ph of water below 6.5 and flush again?

i never understood what checking runoff ph tells you but the ph of the runoff water, and who cares about that?? not me said the bee...

like lots of people have said already and i tend to agree with, i'm not a big ph checker in soil.. soil is a great buffer of things like ph ime, so no need to go all crazy and get all technical, again, imho..

yea run off .. in my oppinion .. is only a way to monitor the soil .. so you can discover drops or raises in the soil and act on it (add lime or do a flush aso) so you need to know what its normal is .. cant use it to mouch els .. it will also drop a lot if your soil keep a lot of salts from then nutriens (witch is often do late in the grow .. logical)

but from experiance I can tell you that if you have a soil on 6-7 PH and water with 6,5 PH it will often come out around 5,5 later in grow ..

but to be sure .. get a soil test kit (8$ at my local garden center)




but as others allready said ..including myself .. a good soil .. specialy a organic one with wormcasting and compost in it .. will buffer the PH ..
so correcting and testing for PH is more for the hydro guys .. aslong as you use a good soil with a PH with in ranges (6-7)


and a last thing .. how did you grow them plants up till now ? I mean 2 weeks in to 12/12 .. they must be dead 20 times by now if your soil had a PH on +8 and if it was a problem ..

sorry...soil wasn't 8 ph,,,water was. but i started plants using aquarium water which had a correct ph,,but was told that aquarium water was bad so i changed to tap water and let it set for 24-48 hours,,but never checked ph,,thats when problems started and i got a ph meter...its kind of confusing for a beginer on here,,you post a problem then get a few responses,,so i hurry and try to do what is said,,then sombody else posts and says no,,don't do that do this... I flushed this morning with ro water ph 6.7 4 gal. so i guess i wait now tell it dries out and start watering with nutes in ph'd water..using super bloom..12-55-6 with .10% chelated iron

here are pics taken this morning before i flushedView attachment 2293312View attachment 2293313View attachment 2293314View attachment 2293315View attachment 2293316

yea it can be confusing when your new .. lots of helpful Ppl. but some to helpfull and some just dont know what they are talking about .. and ther is also often more then one oppinion or right thing to do ..

what I learnd ..
is to provide as mouch info as possible (with out makeing mile long posts)
with Pics (do help a lot .. mostly just to make ppl. get a intrest and look at it in the fist place)

and then take evry thing with a grain of salt so to speak .. use commen sens and logic .. in the end it is only you who can correct or changes stuff .. and just Bc. somebody in here tells you to do it .. it might not be right .. who said he know more then you ? or got the info right ..

so get some oppinions .. try to use logic and use what seems mostlikely and what most Ppl. tells you and do some research on the topic .. then decide what to do .. maybe even go back and ask more quesions or do more research/reading ..

would sucks to creat a new problem .. trying to solv another ..


looking at the pics I think your wher right to flush ..

what I would do now (and remember this is my oppinion .. do your own research .. google is a great tool)

would to only water with clean room temperet water (rain water if possible or 6,5PH corrected tap water) the next 2-3 times you water .. make sure to get a good run off .. no nutriens .. maybe a ts. of black strap molasses to help your soil and provide some K and Ca/Mg aso.

after that I would cut all N. and only feed it high P. nutriens .. with a littel K .. NO nitrogen ! atall ..nothing .. zip zero ..
its for Veg and "green" grow .. to mouch N. late in flowering can realy screew up your plants (do some research here)

P. is what you need or what your buds/flowers need to grow and get dens ..

looking at what I have on my grow room shelf .. I would proberbly use some of my Bat guano powder (15% P.) as top dressing (2-3 Table sppons) after a week of clean watering .. and then just continue with clean rain water .. and add a ts. of molasses evry seccon time .. nothing els .. just let it use up what is left in the soil once the PH allow it to do so ..

p.s.
the clean water I said to use next 2-3 times schould be between 6 and 7 in PH .. most aim for 6,5 .. if your soil is a bit high .. I would aim for 6 maybe 6,2 if you can get it that accurat .. but atlest I would go for the low end if you get my point .. a Ts. of Epsom salt if you have could also help here ..

NOTE: boath Epsom salf and Molasses schould boath be disolved in a cup of boiling water .. then added to your water can before watering ..

pps.

I dont think it look that bad acctualy .. a few curling leaves .. but Im sure it will bounch right back and yield nicely .. think your wher in time .. and one good thing you got out of it .. is experiance .. for future grows .. not many Ppl. get evrything right the fist time .. if any ..

I use molasses and MG as ph down for my tapwater

Just to clear this and he means Magnesium,Not Mircle Grow,little things for newbies can confuse ppl,Weve all been there so good luck.I disagree with Slip,on the N so you might want to read Unlce Bucks threads.Either way is ok,I just prefer a little N in flower.Like Slip says your always gonna get some different ways to do things,like he says Google is your friend.Get several ideas and You have to decide which is best for your application as you can see plant alot better than we can.

No no no. I meant MIRACLE GRO lol. It drops the Ph by about 1.2......which is good for me since my tapwater Ph is between 8 and 9

LOL We know this but, he might NOT.You gonna confuse the hell outa of him.lol

I personally use RO water but the schedule I use puts a lot of the "filtered out stuff" back in. RO water just gets you down to low PPM but as stated before if you dont put some of that stuff back in your plants will be hurting for it. I have well water thats like 300ppm and if I used that plus my schedule I'd be giving them way too much of some stuff. Also letting you water sit is good to get rid of some of the chlorine but you absolutely need an air pump or else itll just go stale... Water starts to lose its oxygenation within 30 minutes.
