Did u grow in soil...........?
I`m new to growing and got 5 widows in 4th week of flowering(looking ok)
And i have 9 powerplants ,at around 1 week from pre-flowers
Both are growing in soil in my 5x5 foot bathroom....looking at your 1 pic of PP im now slightly worried about the space......lol....on 600 hps.
Even though the powerplant are aroun 6 weeks behind they are the same height as whitewidow already.............holy shit
