Hey guys

i am having some issues with Janeco Light Mix, i use a 15Liter pot with clones 1 week older +/- , but in the veg state starts to show a little Nitrogen overdose,
and after like 1 or 2 weeks in flower the plant enters in lockdown because of it.

Soil NPK 12-14-24

If use florakleen to remove the salts will be enough to remove the lockdown?

Have you guys ever had this kind of issues?

Thank you
