Hey Mate,
Yeah.. you overdid it..😥
If you have the possibility to feed her pH'd water with something that wash out the nutes like "Clean Fruits" from Green Buzz Liquids or Final Solution (GHE)... there are a couple of products..
or you flush your medium...
(Amount of water ~ 3 times potsize)
Then start your feeding Regiment again, but half a dose..
Then you slowly increase the amount of fertilizer until you get your sweet spot again.
Hope this helps a bit, good luck and happy trails for the rest of the way...
Cheerz ✌️👍
