Hello, I have a plant that's a little over 3 weeks old in a hydro grow. It took me a couple of weeks to get the ph and nutes correct, so the first 3 sets of leaves have nute def/burn. Anyway, they're dead. Should I just leave them alone, or cut them off? Are they absorbing any light, or simply blocking light to other leaves? Thanks.
I pull of what comes off easy. If there dead a simple pull will bring the whole leaf structure off. If it gives any resistance id leave it on there.
