First post, Green crack veg

Yeah so I measured the runoff yesterday after watering with tap water no nutrients and it was around 3000ppm. Is that ok for veg in soil? Do I need to reduce that # and if so, how? On another note, humboldt says Green crack likes warm and dry conditions, what is considered ”dry”? 40% or lower? I’ve been using a VPD chart and trying to stay in the green area but my humidity has been getting up to 60%.

@Goenner's Greens that 3000PPM is a combination of organic nutrients that were already in the FFOF soil and synthetic nutrients from the bottles that you gave them. The leaves don't look too dark so no need to reduce by flushing. You can probably just get away with feeding plain water the next 2-3 times the soil dries out. Continue to check the pH and PPM of the runoff and you'll see the PPM reduce over the next several waterings. You may want to watch this video if you haven't already: https://www.youtube.com/watch?v=vWuHJhjcc-w VPD is optimal humidity. The plant will still grow outside the VPD green range. 40-60% is a general safe zone for the entire grow. I like to go as high as 65% in Veg and keep it below 60% in flower.

Interesting! Thank you so much for replying, I didn’t think mr.grow it himself would respond to me! you have been very helpful!!
