Are my dark leaves an indication of Nitrogen Toxicity?

Dear growers,

this is my second try with autoflowers and compared to my previous grow i have been using a lot more Orgatrex (~1.5ml every watering) from BioTabs. Because this is the tallest plant i‘ve ever had i didn‘t bother feeding them that much although i have 2 BioTabs in the soil. My question is if it‘s smart to continue feeding them Orgatrex every watering? For about 1.5weeks i‘ve been adding BioBoost from Canna so i will slowly raise the amount so when the buds are forming i‘m giving them ~1ml Boost and ~1ml Orgatrex. The strain is Gorilla Glue Bagseed from Fastbuds and i‘m switching daily from indoors by the window and my balcony.

She needs more light!

They look fine to me but more light might help.

Thanks for the replies but sadly i can‘t really get her more light because it depends on the wheater, i already change the spot several times a day according to the sun.
btw the lamp in the picture isn‘t meant for the plant

I don't see any n toxicity issues.
I don't really see the nutrients doing much good as the plant doesn't have enough light to make use of them. Thats the reason its so tall and thin and can't hold itself up....uts trying to grow out your window where there's more light.
