Are you sure it's not nutrient burn?
What nutes have you given, and at what strength? What size pot? How big are the plants?

Quick question Well my plant has been growing for about 5 weeks now and i think the soil has gotten to acidic cuz new leaves that come in are still slightly burning, but its been growing lol i just want to know what would i need to do if i wanted to lower the acidic level in the soil.
