getting new clones!!!

Im picking up new clones in a few days.( rooted in rockwool)

My first batch of clones looked like they got either nuteburn.
I use RO water and added some very light nutes to about 100-120ppm.

Is it possible to get nute burn at 120 ppm?

When I get my new babies should i use just Ph water for a while or a little nutes is ok

Thanks

what type of system are you going to be growing them with?

im going to put the little rockwoolcubes into 6x6" cubes in a flood n drain system.
is it possible to get nute burn at around 100ppm?

no you wont get nute burn at 120 ppm. I started my clones at 400 ppm and they did great. just make sure your ph is correct.

Congrats on the new members to the family. I have a guy calling me any day now with my new clones! It's damn exciting isn't it!?
