Nobody has helped yet somebody please??

Oh 6.3 2 200w led. Scott's hyponex shitty dirt it's only happening to two of 5 plants and it seems like the marks are close to eachother on the separate plants may be a coincidence. Any info would be great

Looks like bad soil, learn to make subcool super soil.

Read the book, teaming with microbes .

Then youll understand why dirt matters .

Is that a silver exhaust tube running through your plants? Sometimes 'hot spots' will generate where reflective materials are in contact with light. This could be why you see the issues in one spot on two different plants, while the others look ok. It's a plausible issue to look into. It may also be that your girls are running light on calcium. Signs of a deficiency in this element will occur a lot of times in the leaves that get the most light exposure, which may also be an issue, based on your pics. Maybe you can confirm the amount of calcium they've been getting via your feed / soil / water and go from there? Small, purposeful steps will get you there.

I agree with the Ca def. Either use a specific Ca/Mg supplement or something like Epsom salts.

Epsom salt doesn't add Ca. Epsom is Mg and Sulfur. You can add a CalMag supplement or you can add calcium via Calcium Nitrate, among other sources.
