yes. as i told you 700 was too much if i do 500 its okej. tap water here is 150 i think.
i know about the low zone, apropriate zone, luxury zone ,then comes too much but not dying what you are talking about and then real too much yellowing of leafs and visible problems
honestly she is growing too much however you like it the box is too small to suport her until she leaves veg i have to fight her every time after i switch she is not mature soo she is veging for a week or more.
and she is slow at the beggining because the roots are developing, when you dont see her grow top you see a huge explosion of roots.
yes this round was overfeed but last year i had red diesel and at 650 start nutes where droping after one day it was 630. only reason i started this high this season but i guess this random seed is not one of the hungry types
this was after 7 days veg
but this random seed didnt even have half of the roots it started with 2 roots and they went long... maybe because of high ppm or just genetics
