Tap Water???

My first grow and I have 18 plants DWC... Some growing beautiful (15" tall) and some with stunted growth(5" tall).

They are all at 6weeks and I have been going back and forth treating nutrient deficiencies and doing all sorts of treatments to try and get all these plants on the same growth rate.

Could it be that I am using tap water and not RO water???

I don't have a way to distill the water I put into my DWC totes(30gal) and I am starting to think that this is the real problem... what do you guys think?

Any help is much appreciated.

if you want purer water, you can boil it. it takes a while, or go to the grocery store and buy distilled water. good luck

yea i figured that... but I have 3 (30gal) totes and changing the water is difficult alone when I am using a hose to fill it... i couldnt imagine how long it would take if i boiled it all first. I am definitely going to use a diff setup next grow. but besides that, do you really think that the tap water is causing a lot of the deficiencies my plants are experiencing?

I grow in soil and my tapwater is between 500-600 ppm. I had all kinds of deficiencies and lockout until I switched to r/o. It definitely could be because of your tapwater. Do you know what the ppm and pH are? Are you dechlorinating it somehow if it's city water?

I make up 2l of water and water her 1l every 2 days with water thats been boiled then warmed back up to 27oC

You may want to look into a home water delivery service. Hinkley Springs delivers anywhere in the US and they have distilled water option. It's a bit pricey, but you have the piece of mind knowing the girls are getting the best. You can also buy distilled in 1 gal jugs from any rocery store. 90 gals at a time is a lot to change. What about a high capacity RO system?

Buy a Mr. Clean carwash gun and filter your water with the spot free rinse setting. You won't be disappointed.

My tap water is 300-500ppm and ph 7.2... I adjust the water after i fill the totes to ph 5.8 and 1100ppm with nutes. so really im adding bout 500-800ppm of nutes.

I was considering getting an RO system for sure but no money for it now. Next grow for sure I will.

I will definitely try out the MR. Clean thing until then.... Thanks much

Just use the RO water from the Glacier machines out in front of the grocery store. Cheap as fuck, no tracking and it's like 10ppm.

That's what I use. It's a pain in the butt hauling jugs around but it's better than having lockout IMO.

good idea... would b a much easier way to get RO water.... thx laserbrn

I am one week into flower and i've been using tap water the whole time. I just fill a 55gal trash can with a bubbler at the bottom, adjust ph and wait 24hrs before using it. Then again my tap water is very good at 54ppm and ph7.5.

hmmm interesting... whats ur tap water ppm when u start?

whats the best water to use during a grow,that isn't a pain in the ass to get and not too expensive?

Glacier water from out in front of grocery stores. Comes out 10ppm where I live. The tap water is 450+ppm so I use this stuff. Cheap, easy, takes cash and doesn't know who I am. Just fill up a grocery cart full of bottles and fill away. Takes me 30 minutes/wk including the driving to the store and it's all done. No Sparkletts bills, no problems. Sparkletts guy gets suspicious when I need 45 gallons of water every two weeks for my apartment. Fuck that...fill'em up, put them in the garage and go grab them as I need them.

i bought a mr. clean car wash to filter my water.... works like a charm as was suggested to me
