TDS question

I have hard water. Currently running between 350/400 ppm @ 7.1/7.5 ph. I have been adjusting the ph to 6.0/6.5. I am currently using powder fertilizer that a local here makes Veg is at 20-6-16 and Bloom 9-21-12. I also add a B vitamin supplement. I use the B vitamin with both the Veg and Bloom nutes and my solution is running at 1500/1800 ppm depending on water levels in the solution box. Now 1500/1800 is pretty middle of the road for my culinary herbs and they do fantastic without any issues. Cannabis is also fine during the Veg stage. This is although my first go round using 5 gallon bucket for flower. I had always let mother nature do it before.

I have used this system before for melons and tomatoes and never had any issues with salts I guess this could be due to rapid water uptake during fruiting. I have not ever used distilled or R/O water for the NFT hydro unit. What should TDS be running for bucket system with cannabis? What type of water are you folks using in DWC?

The pic is not that good but your plant looks healthy. I use R/O water because i'm on a well. i dont like ppm above 1500 and i try to keep my plants around 700-900 for veg and 12-1400 for flower. I have heard of guys going as high as 2400-2500 ppm but if they dont need it why spend the cash or smoke the chems.if those numbers got the plant to this point i might keep the ppm the same but switch to your bloom food and see what happens.

Fantastic, thank you very much for the info. Im running clone and herbs in NFT unit. Dont have the balls to go 2400, for me and my work schedule that just has disaster written all over it. Plant is on first week of bloom (day 5 today). Sorry about the pic shitty cell phone image. Currently have 250w/2400k bulb running for flower, but I think Im going to add some side light and a chiller to keep the temp down.

my max nute load for AN Sensi bloom nutes is 725ppm... i also run RO...budz are swollen that they are bending over the branches... could be because of Bud Candy too
i got pics in a forum... but they are huge... hope you got a good computer...
