yellowing spots on leaves

Ok so i am 35 days from sprout. My plants are in Fox Farm Ocean Forest Soil and the strain is easy ryder. Its an autoflowering strain. The pictures were taken yesterday. Today, the edges of the spots are more brown and burnt looking. I have them in 2 liter grow bags about half way up and its indoor in a pc case.

Anyone know what the spots are from and how i can fix it?

I have no idea what that would be, because the plant looks pretty healthy, otherwise. Hmmm.....I'd say to look for some kind of pest chewing at the undersides of your leaves, or if you're foliar feeding, make sure you don't do it in the intense light, don't have it mixed too strong, PH'ed, etc....That's an odd one, one that you don't see too often.

How much light are you using? That could be the problem but the plants really look healthy I would give it some time to work itself out.

i had 126 watts in. now that i switched to flowering bulbs i have 204watts. It actually looks much worse today. brown and yellow tips, crispy and burnt looking. but only on part of it some parts of the plant look completely healthy

So it's a high presure sodium..? The spectrum of light can make a difference. Also the temperature. You need between 5000K and 65000K for the veg, otherwise known as daylight or sunlight. These lights give off more blues and greens that the plant needs to make oxygen. Just a suggestion though good luck.

it looks more like nute burn to me

Theyre CFLs. The ones i had in were all 6500k for veg. now i mostly have 2700k for flowering

What nutriens have you fed them ? Have you tried flushing ?

I'd flush them. My bet is nute burn.
