Hey FatBluntz,
As luck would have it, I too started my first dinafem diesel on the 7th like a day after you so if I can help in any way I will.
Im Currently in a 60x60x140cm tent with a mist making machine, self made shade, 2 X 125w 5700k CFL's and a 6" clip-on fan to circulate the air blowing JUST under the lights, I'm in "whole life" compo in 4l pots (really nice fluffy compo this is) Temps around 28-30C and RH is around 70-80% with mister on and around 50-60 with it off (mister set to come on in hour intervals for an hour) So far I've used PH balanced room temp water for first week or so, then started to use "pre-shoot" (given to me by a friend) for around a week, then pre-shoot AND Bio-grow (less than half strength) for another week now im on well into my 3rd week I've come off the preshoot and just using half strength bio.
My advice to you is to veg for another 2 weeks from the looks of the pics, mine is twice the size now but I'm not buddin any time soon, gonna use this one as the mother, few cuttings to bud while it gains its "toppings" (4 tops in total) then gonna bud that so probably lookin another 8 weeks myself before I bud the mother, want it nice n stocky like
My second advice is to under feed the fucker, remember, a plant WILL find moisture from somewhere, and when it has less feed the roots search hard for it, hence bigger root mass, hence bigger yield. My last ones from seed suffered a lot from over feeding but this one I've held back loads, basically I'm in a 4l pot, I feed arounnnd 250-300ml every 3-4days, and trust me they flourish!!
Good luck with your grow mate, cant wait to see the updates, will be good to av someone to talk to doin' the same strain at the same time!
P.S. shouldve mentioned this really as this is a big factor, along with the diesel I have 3 autoflowers which require 24/7 light, so the diesel has been under total light since seed popped, I suggest this until you want to start to flower mate as it will just flourish this way, if you can afford to run ur lights that long and it doesnt get OVERLLY hot and stays at a good temp, also get one of those mist makers, i got one in a jug of water with a polystyrene plate over the jug with a hole through, this stops splashes but lets the cold steam come out the hole.
Don't think I've missed anything out but give me a heads up if you need any help mate.
Take care!
