Reverse osmosis question

Hey all,

I,ve been watering with well water and rain water, and have been having nothing but problems. I ph the water 6.6 - 6.5 but im sure we have hard water and or metals. Ive tried brita filtering but still have yellowing of lower leaves every time I water. So I was thinking of getting a reverse osmosis filter. I cannot hook this up under my sink though. Can I do it through a garden hose? Are there any good models anyone can suggest? I can spend up to $250

I got a portable, $150

here you go. I have the little one.
Whole house water filtration system, reverse osmosis, refrigerator water filters
Portable Water Filters

theres one on ebay for 120 and it does well .....50 gallons and a 75 gallon a day .,,,by the way how about adding more nitrogin to see if it turns green and are you waiting to water when their dry or .......

Thanks guys for all the info. To answer the previous question, yes I am using half nutes right now.

all good RO systems come with a garden hose connector...

i have a stealth 100 RO system

get the push in quick connect adapters.....saves headache and water leaking trouble
