I am a little concerned because a couple of my succulents (which are larger and pretty established) have started to turn colour at the growing tip. One is a Burro's Tail and the other is a light blue coloured echeveria. Any ideas why they might be going pale/yellow at the newest tips of the plant? Should I repot them with new soil? Nothing out of the ordinary happened prior to this so I am a little mystified as to what change in their environment could be causing the change. I gave the burro's tail a little fish emulsion a few days ago and it doesn't seem to have made any difference at all. I didn't give any to the echeveria yet because the soil wasn't dry enough for a new watering.
Very eager to benefit from the advice of seasoned succulent growers.
Thanks!
M.
