First Auto Grow

everything is going well except they just keep on vegging. looks like flowering might start this week. oh well bigger yields. took care of their N Tox last week and got them on the right track and dialed in. released stardawg 1 from her week of LST except the main trunk. Will release that once I see some buds. Edit: noticed a sulfer and mag def on a few of the plants. couldnt tell they were yellowing very well under hps lighting. treated with epsom salt foliar spray. and will add epsom salts to their feedings in addition to the tap water/ cal mag they already get. they are taking tons of cal+mag EDIT on nute lockout: figured out whats been going on finally. I started reading too much crap again. said to flush at half strength blah blah blah 20% runoff blah blah yOu CaNt OvErWaTeR cOcO bs. I over watered because I read that you dont have to let them dry all the way in coco and that it was actually bad to do so and it harms the roots. well thats crap. they got over watered and got a zinc lockout on a few of them. GG got it the worst. need to let the pots air dry then flush at 1/2 and continue my regular feed. im kinda mad rn ad immobile deficiencies at this stage are really crucial to yield and some dumb misinformation screwed my yields and probably potency. on my one freebie. taking everything I read with a grain of salt from people on here and other forums.
