Leaf spots

9 years ago

last modified: 9 years ago

I've been keeping a close eye on the leaves.. I had noticed spots showing up.. But they continue to spread. I've searched up what it might be and not getting anywhere... Plus, I read things and then another site contradicts that info. I do have one or two where the leaf edges curl down.. And another where the leaves just gravitate down.. But one that just points straight (which looks just odd lol) So I thought to ask here.

Also.. My local fair is underway currently and I couldn't wait to question the floral dept about av. They had no idea what water wicking was.. And thought it was interesting... From the 4 that were there.. I guess symmetry isn't priority either.

OK back to these spots.. Im thinking the brown is sunburn? They are a few inches below an led light.. I measured the light intensity on my phone its around 400 up to 600 footcandles.. But maybe they are just too close? Im measuring by putting my phone just above (without squishing) my av.

As far as the white/yellow.. I assume is a water issue... I've read where water has gotten on the leaves..(which im very cautious about and making sure the temp is room temp)

Or water is too cold.. But I water wick and when I refill them.. Its from a watering can that's been sitting in room temp. So is that still possible?

Cosmetic damage.

The one with a mouse ears is going to be looking even worse when it is done... it is working hard raising the babies - no energy to keep itself pretty.

You are probably right about the second one. If you can - increase the distance to your lights. LEDs can have a harsh ultraviolet rich spectrum.

I have some very healthy plants that have had similar damage to the leaves. They have been like that for a long time with no impact on the overall health of the plant. The damage to mine was 90% sunlight related. (All my plants are under lights and I had to do a bit of experimenting to find out which plants were less light tolerant than the rest.) The rest of my damage was done by an incorrect PH in both my water and my potting material. AV's reportedly prefer a slightly acidic PH in the range of 6.2 to 6.8. My PH was over 9 which after a while started to affect the ability of the plant to absorb the nutrients it needed. With those issues corrected, I don't see much of that coloration anymore. I do have a couple plants that were bred for that light green/dark green leaf pattern. Not certain that yours doesn't fall into that category.

sorry i'm a day late in responding..yesterday was busy running errands ..then i messed around with my av's..and that takes a while..then i was just beyond tired lol...

so i purchased a ph, moist, light meter at lowes..i normally use an app for light..but i've been wanting one for moisture..now for light, its saying i'm in the dark..100ish..and i'm assuming its in lux meters. every pot i test even non av's..says the soil is very alkaline. I've googled how to up this..but i'm getting results to repot and replace in av soil...they are all repotted recently and in av soil mixed with perlite. So i'm confused.

as for the light issue..i have limited space..my 3 poinsettias take up a whole shelf plus one is so big..it takes up so much room that other shelves are short..i figured because its an led light and when testing the light it gives the amount of light they needed..i never thought that even if that was right being so close would harm them. So beings I'm not able to raise the shelf height..i put parchment paper (twice) around the light to dim the strength of it...would this be helpful if i cant change the distance between light and plant?

i do have an av thats using the same soil and water i use for my other avs..it sits just below the kitchen sink window facing the east...and it has none of these signs..so i knew from that..something is up with mine
