I guess my question to you is how has the weather been since you planted them? Wind and cold damage is usually the problem when the edges of the leaves turn brown. The only other cause is overfertilization. Excessive salts in the soil can cause leaf tips to turn brown. There's not much you can do about either - the affected leaves will eventually die and fall off. Be careful with your watering (one deep soaking per week) and don't feed your rhodies for at least 30 days. Hope you see some improvement soon.
