i'm 29 days into flower with my white widow, this is my first grow and I would like to know when to stop using nutes and to just use water?

I do not want my smoke tasting all chemically

i am lead to believe you should stop nutes 2weeks before you harvest then you can either use a rinse solution which you can get from your hydro shop or plain ph6 water. some ppl believe that plain ph6 water creates a cleaner taste. you should harvest when 50 - 75 % of the hairs on your buds have changed colour.

you will have to watch them to see how long it takes for 25 % as each strain is different. once you hit around this 25 % I would start using your prefered method either water or rinse solution. you could try rinsing 1 and water the others.

hope my advice has helped
