Bonnie,
It looks like fertilizer burn to me.If you leach them really well the new growth should be fine,but the spots on the older leaves will not go away.If it's real bad,you might have to repot them.

That's too bad.It was such a beauty.Try giving the leaves a real good bath and sticking 1 or 2 down to root.Some of the build-up might wash off.

Is there any chance that water spots sat on the leaves? That can cause browning, especially if the plants were in a cool place. I'm asking because if it mostly happened toward the center of the plant, that's where you can get water sitting if you don't dry them off carefully after top watering.

Bummer to have that perfect look ruined, but yes, the plant should grow out of it.

OK, I wasn't sure... you mentioned "leaching" which I figured meant top-watering to rinse away fertilizer buildup in the soil (something I need to do more often with my plants!).

looks to me, like it needs repotting.I bet it has'net been repoted for 3 months or more, hence the fertilizer built up. In Wicking , with very little soil this is what happens. and then each plant is different...

Your right, i have not repotted in awhile. Will do that today.Been so busy lately, my plant room is a mess. lol Thanks for the web site. Found that helpful. Yes leaching is where you put your plant in water just above the soil & let it bubble to rinse out all the fertlizer.

I let the water run through for quite a bit to get the residue of fertilizer out. Much prefer to re-port every 2-3 months with important plants that is.

I now collect water from our(condo) springkling system which is well water, full of sulphur, not sure if this is good. Should be better the the chlorinated county water. helene

I had my AV's in my office and they were quite happy. I retired, gave several AV's away and kept some. They weren't happy in their new home - AV's, new place, not happy. I moved again, big vanity in bathroom, east window, AV's were somewhat happy. Received as an early Christmas present a four level light stand, placed it in another room. Two months later I find out AV's not happy - powdery mildew. OMG, I was crushed. In a panic I cut all the leaves off that had powdery mildew and it left the plant with only the center leaves. These are now getting the mildew. I don't know what to do or why they're not happy. When I set the light stand up I thought the light was to close to the leaves, say 2-3 inches from the larger AV's. I researched the problem and it said to much humidity (NOT!) or not enough air circulation - go figure. What do you think forum readers?

Hi,
I'm sorry to hear you are having problems.Usually mildew is caused by lack of air circulation and in winter sometimes wet and cool is the culprit.Spraying above them with Lysol and letting it settle on the leaves is one solution,or spray with 1 part low fat milk to 9 parts water,let dry before placing under lights.

In my opinion 2-3 inches is much too close to the lights if you are using 2 to a shelf.I would try 8-10 inches.

Lysol works for me too, but, I also now water my mats using Physan 20, which is also effective against PM, among many other things. Yesterday I started running my lights at night to keep the plants warmer when the temps are the lowest. Cold temps, moist conditions and no air circulation at night were the cause of my PM on violets on the bottom shelf of a plant stand next to window.

GrowHappy, I started to do the same thing, run the lights at night for warmth. For Pete's sake this is central NC and we have 9" of snow on the ground! I hope that you are all safe!

Mrs. Bonnie, you might want to check your ph. Another friend on a different forum had the same problems with spots just like yours, it ended up being her ph.

I have come to the conclusion that you have to be a scientist at times to raise these beauties.
