Help why do my leaves look like this???

I need help figuring out why my leaves look like this. 2 weeks into flowering in an outdoor grow. Flora Series nutrients in 45 gallon soil.

Does anyone have an idea? I don't want to lose these

Nevermind. sorry

Never mind what? I really need ideas

Are those old growth leaves? Meaning those have been on the plant for a while... subject to environment issues... looks like burn spots from maybe nutes splatter or chlorine water spots burned into leafs, like my maple tree in back yard...what does the whole plant look like, new growth green and nice? Under the leaf, worse or better ? Good Luck !

I think you have a pest problem. Be sure you use natural means to get rid of them so you dont poison yourself

A photo of the whole plant will help an accurate diagnosis because it could be several things
