Hi there,
one of the first times i grow soil, usually i use hydro.
So the new growth are yellow or light green, 1 week of 12/12 for this male. It began when i flip to 12/12. I gave balanced nutes with tap water (ec=0.25), not too much, and the growth is quite slow...

Hmm, IMO this looks more like a Zinc deficiency. Generally this is due to PH being too high causing lock out.

I'm not as experienced as some here and I am an organic soil grower but I hope this helps lead to resolving the issue.

One reason for the yellowing of the tips like this could be having your lights too low.

Thanks guys, i think Imiubu is closer to the truth. At first i diagnosed a Calcium or Zinc def. It's true that during the first weeks, i watered with tap water at pH 7 or 7.5. So it can be a pH problem. After, 2 days ago, i watered without nutes but with pH 5.8 water. But it does not seem to cure. So today i put the male in a bigger pot with new soil ( rich one and organic) without watering because the roots were a little too wet.
So the key is to water with pH 6 (or so) water? Do you water by the bottom or by the top?
I've read that rain water is pH 6.
