Pictures may help.
As Carol said, yellow leaves usually mean water.
Too much light usually means lime green or very light green...unless they are really burnt then yellow into brown and crinkly
But BRTs tend to toss old foliage for new when their environment changes significantly. When mine go from inside to outside they will drop most older growth...the dropped growth turns yellow before it falls.
If you increased the light intensity a lot, this may be what's happening. Shake a branch...do the new leaves fall off easily?
Mine grows new leaves with bigger leaflets when inside for the winter and smaller leaflets after I move it our for the summer.
If you open your profile and add a nearest major metro and a grow zone, people will see that and can add more climate specific advice.
