Are there any negative side effects from a low PPM/TDS?

  1. So I have a plant about 5-6 weeks into flowering, it has some pretty good nugs, I didnt want to really give it any nutes because I got some burn at first and was kinda unsure. But kinda late into flowering i started out 1/4, 1/2, then full strength. ive been using the lucas formula and just tested the PPM and got 175.. lol can this do anything other than slow the growth?
    any advice is appreciated

  2. No way full strength is only 175ppm. That's way low. If you don't see any deficiencies, wouldn't worry too much, but during peak flowering should be around 800 ppm or so;)
