n toxicity or no

Definately an abundance of nitrogen, the odd leaf tip is showing potassium burn and the curl could be osmotic stress. If I was to guess, you've fed them a little too much. With nutrients it's about finding the sweet spot; a common misconception is that high fertiliser strength results in increased yield - it's just not that simple unfortunately.

Hey growmie... you haven't been keeping up your diary if this is your Night Queen grow. She's looking very good but since you haven't updated your diary, don't know what nutes you're giving. She is looking pretty dark green which would tend to make me suggest cutting back on your nitrogen heavy nutes.. plants in flower don't need a LOT of nitrogen but they DO need some.... more than anything, they need potassium and phosphorus so if you're not giving bloom nutes, do so now! You can also add a PK booster that will help fatten up the buds... Good luck!

Looks more like a potassium defincecy give it some P-K .

i think i i will need about 13-14weeks for this plant... does it look good and can i expect 30 grams? i would be happy for 1st time

details strain: The name is an accurate one since most of the plants are a very dark green, almost black.
