While I am not familiar with which scale your meter is using, I can confidently say that 238 x10 is intended to read as 2380.
It depends largely on what the plants are used to sitting in. IOW how big of a jump is 1700 from what they were at. My guess is that they can not handle it, and it only takes a few hours to get the first signs of nute burn.
that is interesting, 2000 is as fae as i went so far, jeez 2900 i guess i will have to veg close to 2000 to flower at 2900?I never empty my 50 gallon DWC Recirculating 12 bucket Rez and i run my system @ 2300-2900 PPM all the time and add water to top off when needed, I have no Nut Burn and they grow like wildfire
I use full load of nutrients every 10 days with 5-10 gallons of water to top off weekly depending on size
im running 2-2.1k ppm late in flower without issues. in fact the plants are sucking up as much juice as they can get their greedy fking mits on and making me go broke for their fking food.
