Did it get splashed with water?

That's what I thought, but no. I repotted this plant and after several weeks it started looking this way. I have another that looks the same way. My routine: LIGHT 12 on 12 off, WATER when needed, fertlizer water everother week, plain water the rest of the time. REPOT try to every six months. When repotting I 'm not around water until I finish repotting then water from top until water flows through pot. I'm very careful not to get water on leaves.

What's the strength of the fertilizer you are using?

Jack's classic blossom booster 10-30-20.. Useing the smallest part of the measuring cup and add to 1 gal of water and let set for a day and then water..Let plants set for 30 minutes in water and then remove water from saucer.

I might try no fertilizer for a while with distilled water if possible.

Something was off with a culture - they are very vulnerable after transplanting. Can be as simple as you watered them heavily in the evening and it was a cool night...The plant will grow out of it

I second MissTee - keep off the fertilizer fo some time. If you used the ready AV mix you purchased - it comes preloaded with fertilizer - so you do not need to use anything for a couple of months.

People who grow for show and use Bloom Booster - only use it several times at a certain amount of weeks before the show to stimulate bud setting - and then return to the balanced one. Normally with numbers about 20-20-20 the dose should be 1/8 of a teaspoon per gallon - and since you water with plain water every second time - 1/4 of a teaspon per gallon would be just right. With a bloom booster hard to say - it is not an optimal fertiizer to use around the year.

But it is a general observation - I do not think the Booster was the cause of your burn spots.

Good Luck
