Hey just starting a journel

My plants are about 4 weeks old now and they are doing pretty good cept i have a few problems.

First, two of my plants have started to have leaves go partially brown, what should i do?

Two what are possible techniques i could incorperate to create a higher yield, I.E. FIM tieing/training or topping. I have already topped three of them and they took to it fine.

other then that any other recommandations to improve yield.
