ok so 17 views and no replies, well maybe ill put some better pics on

i have no clue what day she is on veg growth because i originally planted her in december, she went through some major slow growth in soil, i then switched to dwc in january, she took about 2 weeks to recover and now this is her.

ok well ive backed off on the solution so hopefully in a week or so it hsould go away, if not ill add more water to my solution.

also does anyone know how to clean stained roots? using floranova series really stains the roots and gets me kinda worried if its root rot or not

Train strain you said you've looked up info on ph and nutes. your pH is lowtry not to let drop below 6.2 if you can, because as you may know as pH drops some nutes become more and some less available to the plant. so even though your plants are healthy and you are Not over feeding they can still be burned. also H2O cahanges weekly if you are not that experienced or for the sake of ease. Anyway, good luck It is looking good right now and i am sure it will get better. Oh and don't sweat the root color. That's all it is, color. Those roots you showed us look fantasticly healthy.

6.2 is waaay to high for hydro...

Changing the res twice as often creates MORE work, not less...

Where are you getting this info?

Check...

thanks for the info gypsy and thanks some what homebrew, either way ive done my research, i know what the solution has to be as in ph, ppm and temp. otherwise im a complete newb to be honest. ive done a few soil grows, just a plant here and there and decided dwc was the way.
i was thinking it couldve been nute brun because i did have the ppm up too high im pretty sure, i was up at around 1000ppm when i first sighted them but even since ive lowered the food to about 700-800ppm im still getting a few spots, just onna ride it out and see where she takes me
