Your feeding them way too much, everyday with nutes,why? It says feed for 2 feedings and then flush the 3rd feeding and then run it again.
Outside your nutes can spread out ,inside they're in a tiny space on top of the roots!

Bro, my first grow i had 3 150 watt hps flood lights from the Home depot and a small fan I had in storage. I never had anything to tell me the temp or rh and all i used was miracle grow!
Till this date that was the best weed I've ever smoked and I've been smoking for 35 years.
All this crazy...
The seeds I'm growing are from Strong Seeds, Wedding Cake Autos, and they also repeatedly stated how you will be harvesting your plant in 7-8 weeks!
Today is the end of week 9 and I still don't think they're ready.
Check them out @ the(Confused at Harvest) thread.
Until then, grow with a purpose!
