USING r/o SYSTEM FOR WATERING

[shoulderpain]

I am new to growing and have been using reverse osmosis for water,
I am using advanced nutrients IGUANA JUICE GROW, IGUANA JUICE BLOOM, AND CAL MAG BLOOM, CAL MAG GROW.
I add 30 ml of cal mag bloom for 5 gallons of water, I do 1/2 strength of either grow or bloom neuts. for some reason the new growth turns yellow the next day. Am I missing something.I didnt have this problem when I was using tap water

Check your pH before you start fiddling with anything else. I'm betting this is a nute lock out.. almost like your not getting any N or something.

Check this link for a pH scale for nutes:
