SOIL Burnt leaves

My plant is in flowering stage, day 42. I just got a new vipar spectra light about 2 weeks ago. I PH my water to 7.0 and water her twice a week.
My leaves are doing this weird turning. I can't particularly match it to what I've seen on Google.
Any ideas? http://imgur.com/a/2lLJI
 
That's the kind without time-release nutes, yeah? I realize I worded my question poorly, I was thinking the pH could be causing lock-out. Growing in soil you want to be between 6 and 7 -- if you look at this chart, it shows that watering at 7 leaves very little room for error. I think it's better to shoot for the neighborhood of 6.2. Even then, it's a good idea to let that number drift a bit (i.e. one watering at 6.2, the next time at 6.5, etc.) to help make sure your plant soaks up as wide a range of nutrients as possible.

Not saying that pH is the problem, just that it could be the culprit. Also, note that I'm only on my first grow. I'm sure someone with more experience will be along with helpful information. Good luck!
 
Thanks for the info. Good luck with your first grow. I think I might lower my PH and see how that goes.

🌱 Is it happening most to the lights that are close to the new grow light? If so, maybe the light is a little too close and they're suffering from light burn? I know Vipar Spectra lights are really powerful and I believe it's recommended they be kept 24" away from the tops of plants.

Additionally, cannabis plants like the soil/water to be a little acidic. So instead of PHing to 7, it might be helpful to PH a little lower. Everyone agrees it's good to keep it between 6-7 in soil. Now I am not a soil expert, I've only grown in coco/hydro up to now, but I'm growing in soil for the first time right now, and I've heard they actually do best at pH 6-6.5 in soil. That's what I've been doing and it seems to be working really good for me at least :)

It's also a good idea to check the pH of the runoff water to see if it's a lot higher or lower than the water you put in. If you're putting it in at 7 and it's coming out at 8 pH you know there's something going on with pH in the soil! 🌱
 
🌱 I've never grown with it myself, but I have heard that it's common for cannabis growers to run into problems with Miracle Gro soil for some reason, especially if it has slow release nutrients or "moisture crystals" 🌱
 
No Title

This is what I'm taking about.

Ok great, thank you. I thought that might have been the problem. The pattern of the damage didn't match any of the deficiencies I was looking at.
I just flushed her 3 days ago. Do you think the PH test would be accurate if I flushed her again?
 
🌱 I don't think you need to flush again. Just water with the correct pH the next time you water, and test the pH of the water coming out the bottom. To be honest, I really think it's light burn since it happened right after you added the light. How far away is the LED panel from the top of your plants? 🌱
 
I know GWE is strongly against using it. In this tutorial, they mention the Organic Potting Mix (not sure how different that is from the Bed Soil) doesn't have the time-release nutes but even then they recommend against it due to poor drainage.
 
🌱 Vipar Spectra recommends keeping their LEDs 24" away from the top of your plants, so maybe try moving it up 6" and see if that helps? You're keeping it 25% closer than recommended 🌱
 
Great informational help berrypilot . I did move my light up, like around 31" above her, and the light is still pretty strong . I hope she bounce back🌲 she to beautiful to wither away🍃
 
So I go and check on her and the leaves that had small burnt spots on it has expanded to where the leaf looks almost dead. So I wanted to know if that's supposed to happen as its process of being burnt if not somebody give me a heads up on what I should be looking into to make it stop.
