og is a food whore.. shit i give them 750ppm of nitrogen and
calmag right when they root and go into my dwc system... then it gets bumped real fast to 1000ppm... when i switched this last run to 12/12 i was at shit i dunno 1250-1300ppm before even going into flower. and i will top them off at 2000ppm of bloom
calmag and kool bloom. before my 3 weeks flush. and not a burn anywhere on the leaves or in the buds.. and let me tell you i got og kolas right now that are just under arms length and they are a true 3 weeks into flower. im talking insane og dank....hahahahahaa i take all my og at 70-75 days nothing earlier i like the weight it puts on those last 2 weeks. you can go from a 2 ounce plant to a 4 ounce plant in those last 2-3 weeks. trust me on that... rock hard dense as all hell lemon pledge pinesol kerosine smelling and tasting buds......ok lt me help ya a bit here...
i run dwc lucas formula as well. but i run 12X 5 gallon at one spot another spot i run 50X5gall and an old spot of mine we ran just under 200X5gal alll dwc...so i ahve some experience here...oh and all the grows were og and
Chemdog D and
Chemdog #4 and underdawg cut. so everything you said sounds great 600w co2 and all that jazz... start them off kinda chill until you notice they are growing once they get growing hit them good with nitrogen and
calmag.. those are your friends with og... og is a cal mag whore.... she will eat as much of it as you can throw at it... the longest possible veg and as much lst and topping or fimming or training you can do to get them to bush out... if you can set up a trelis and weave them through the trelis kinda like a scrog grow... og can be lanky if you dont stay on her with supercropping or lst.... when she starts to stretch pinch the stem ie supercrop. this will cause her to branch out more.... if you can veg them for 20+ days in a dwc you will have pretty large plants if you have the head space that is. but they will yeild killer for you f you can get them fairly big and bushy.... any other questions just pm me.
