Hot Lips Salvia - Leaves Turning Yellow
We planted a bunch of the beautiful hot lips 3 or 4 weeks ago and they looked fantastic when they arrived. We are not sure why they are looking somewhat thin and not too happy and would appreciate any help. The soil is medium moist according to the moisture meter.
Also, it was very hot for the last two weeks here in Los Angeles, followed by a slightly more overcast and humid couple of days recently.
Thank you all in advance. I attached current pictures, as well as one from what the plants initially looked like.
