Spots on leaves first week into flower

Pic 1 is nothing, pic 2 looks like nitrogen burning, from probably feeding too much and too often.

It looks like you may have been a little high on your nutrients to cause the leaf problem but with it only on the odd leaf you may have already fixed it. Try alternating feeds and water so you feed then next time feed again then next time after that water. That way if your getting salt build ups it will help flush it out.

First pic appears to be something out of your control. Second pic has a few things going on. Frankly if this was me, I’d be assuming some over fertilization is going on. Appears to be some slight N tox showing.. this can lock out other nutes. Maybe pH is causing this

Very early onset of nutrient burn, cant imagine its potassium, plants take salts up the stems but has no way to get the unwanted salts back down, this causes little deposits to sit within the layers of leaves causing "chemical burns". NPK RAW Enzymes are Uncut, Tech Grade Enzymes which will help neutralize the salts (little goes a long way) NPK RAW Humic Acid contains 59% Humic Acids derived from Leonardite which is the most concentrated, water Soluble humic acid product on the market today. In nature, humic acid has a buffering effect on the pH of soils. It can raise the pH of acid soils and lower the pH of alkaline soils depending on what the plant needs NPK RAW FULL UP. Trust me.

The first picture looks like you may have got some water on the leaves while you were watering your plants and it magnified your light and left a little burn spot on it, second pic looks like beginning of potassium deficiency.
