Since I moved my Lemon Drops to a different floor of the house some weeks ago they've been looking more and more shaky. They're all 24+" and still growing at a steady pace. They all have plenty of buds (none dropped and none flowering yet), but some weeks ago they started getting these burnt leaves that started out as just black stuff around the edged of some leaves, but now look more sickly:
Lately I'm also seeing some dropped leaves and some yellow ones:
I thought yellow leaves usually indicated N deficiency, but I have a hard time believing that here. Could it be iron? The fertilizer they got does contain iron though...
Today I noticed one of the larger leaves looking bad in a slightly different way:
One or two of these plants need a larger pot, but the others have plenty of room to grow and they all show the same symptoms. I've only fertilized them twice with NPK 5,6-2,0-7,1, but I stopped that and cut back on the water (weeks ago) when they started to look burnt.
The newer growth looks healthy enough to me:
.
And the red Hab and Early JalapeƱos they're hanging around with have none of those issues.
Is this something I should be doing something about or do I just need to give them time since the newer growth looks fine?
