Dark brown spots on leaves/tips

[Oful33]

Ups

Not quite sure what happened, maybe soil is too hot, maybe she didn't liked the slowly releasing nutrients "tea" I fed her yesterday. What I did was basicly put that slowly releasing tablet in a water for about 10 minutes, (it's a tablet made of loads of tiny bubbles). Few of the bubbles have disconnected from the tablet. I removed the tablet and result was few nutrients rich bubbles in a water. After 2 days of waiting, I took 1 tea spoon of that mixture and mixed with about 3l of water. Watered her. It think it was very mild so I would find it hard to believe it's nute burn.

Any suggestions? It's not really yellow, It's more like dark brown tip.

Watering her with water PH'ed at 7. Runoff is at 8.

looks like nute burn to me. What tabs are you using?

Hey welcome to the community.

Here are some helpful links for troubleshooting nutrient issues and leaf/plant deficiency. I use these all the time when I start to see issues in my grow.

I believe that ph to be to hi. Bring it back to 6 mate. And if the tips weren't brown before the nute feed that could be it. But i believe a ph of 7 would cause nute lockout. So as greensmurf has supplied great links id look and learn. All the best.
