Lowryder 2 in waterfarm drinking like crazy! Nute Add back Question Please Advise

My LR2 in my waterfarm is 2 weeks into flower and are drinking 1/2 gallon a day in water from my rez lol i have currently been changing nutes weekly on tuesdays but at the rate there drinking now after 4 days they have used up all origonal nutes and are mostlikely sitting in plain water im wondering if i should switch to adding a nutrient solution back to the rez as opposed to plain h20 like i am now? what are the expert opinions? any advice will be much appreciated thanks

haha that post brought me up to MARIJUANA TOKER !!! hahaha

I have a Nirvana Northern Lights @ 8 weeks of flowering drinking 2 or more gallons a night.
You could ad a controller to get more water reserve in your setup.
I also give nutes on TUE and then rest of the week plain water.
Do not give nutes more than once a week imo.
You'll do fine just check it everyday for water and ph...
