Help now what's happening to my girl!?

Aye mate ill just basically agree with the other 2. Looks like a bit of a ph situation and I'd use just ph water for a couple of feeds, if your in coco add that wee bit more. Roberts, who answered to you. Check his diary's, he's got great information in a simple to understand format. He gave me some advice regarding coco on my first coco run, I've not looked back.

i tried looking at your diary to see what youre feeding them so i could give some better advice on what to do to be helpful. make sure your water is dechlorinated. i have to boil mine because of the chloramine which wont evaporate out on its own. byt the lower leaves look like wither chlorine burns or calcium hungry plants which can look similiar but the top looks like phosphorus toxicity which can also cause plants to have cal/mag looking symptoms. depending on what your nutrients are and media. i would flush the soil well with just plain water for the next couple feedings. try to get more runoff than normal and then add a calmag supplement. also youre so close to harvest, i would just stop all nutrients and let her fade and finish and chalk it up as a learning experience. you only have a week so your plants in the home stretch. best of luck and anyother questions, feel free to message me and i can help you figure it out in a more detailed

It looks like you are not getting adequate run off at feeds and your experiencing a salt build up. Which has also likely put your ph in a lock out stage.
