Pinpoint, transparent spots are often a sign of spider mites, as the Wiz says above. Having said that, the necrotic spots I see on your plants appear to be on the large side, meaning either they are not mites, or (worse case) the infection is getting nasty - you should be seeing small webs forming on your buds.

If you have a decent magnifier, have a look along the main vein of an infected leaf - you'll see them moving.

Yeah wow let's hope that it isn't mites. As Doobie said grab a magnifier and have a close look. If it's mites then it will be time to do battle with the little bastards. Good luck, hope it isn't mites.

no mites, that was the first thing i thought. i saw one leaf with the calcium spots, but i still dont know whats this is. do you think its genetics?

so those transparent spots are very visible on one plant and three dont have these symptoms. i think it might be cause i just added humbolt county's plant finisher/hardener. i put a little less of the hardener than directed and used a little more nutes then directed on the hardener label. it says to add 1/3 of the regular nutrient amount for two consecutive waterings. my second watering is today should i do it again? also this is my last nutrient watering, ill be flushing after this

Do the plants need to be fert'ed again ? Personally, I don't go by labels on bottles, but by what the plants tell me. If you recently fed them, and all looks healthy, leave them alone and water only - as needed.

Learn to read the girls, when to feed, water, and when NOT to. Another cliche, loved by OG and myself: less is more.

its looks like a late stage of P deficiency. dont really know how to adjust it but all im doing is flushing and spraying with water. Then one more go with the Flower Hardener. im also gonna raise my light a bit more(already raised it 8") and add 1/4 nutes rather than 1/3. and then probably one more run with nutes after that. then flushing

How far into flower are you? Are you using Gravity? IMO fucking around with too much stuff is a recipe for disaster. Especially if you don't know what it is or how it works.

To me it looks like you only have a few weeks til harvest. I have never seen that color on leaves before. Looks like some warped shit. Water only from here on out is my advice.

Question. If you gave them Gravity, and some deformation/color change occurred, why would you want to give them more? Most people don't seem to realize that they are the ones causing the problems that arise while growing mj. If your plants are healthy and you give them something, and they become unhealthy, don't give them that anymore.

your right i didnt feed them any of the hardener, i thought about it and it says dont feed them with that if they are stressed soo... i gave them one more run with the nutes and after that im flushing. Red hairs are starting to form nicely around the thick buds. ill post some pics monday

nice plant!!!
