2 weeks ago, I flushed my plants because of a nitrogen toxicity.
Then, I fed them 3,5g of maxibloom (half strenght), noticed it wasnt enough and gave them a full dose a few days later.
Now, my bottom and middle leaves are turning yellow, almost white from the start of the leaf all the way to the tips.
I have never seen this problem before and pictures of deficiencies/toxicities doesn't help.
