nice job man. your looking good.
i have only shown 2 grow on RIU and one on another site. have a few more under my belt. i have done months of research before i gremed my first seed. i am by all means a beginner. so the advice i have for you would be much like dude said before:
take all the advice given to you as a opinion. none of it could possibly apply across the board to all people growing and all strains grown. you could not possibly recreate the identical condition as joe pot grower across the the country. hell my grow space condition change as the outside season change. the variables are so enourmouse that to try and copy excaly what someone else is doing would be impossiable. not to mention that in a ten pack of seeds you could have many different phenos within those seeds. that alone will effect the whole process.
my advice to you would be get a PH pen and a TDS or PPM meter. without these two tools you are sure to be frustrated. or atleast guessing and asking whats wrong all the time. with these tools you will know whats wrong. but you have to know how to use them, thats where the reading comes in. read in the FAQs here and every site you can find about PH and nutes.
as far as nutes go i use rockwool A & B from sunleaves. very simple. there is ton of shit out there. many of them are 2,3 ,4 part chemicals. seems like alot of pissing around with chemicals to me. more variables to the whole process. a 2 part system can hardly be fucked up, even by a new grower like myself.
as far as the increase in size from veg to bloom. there is no possiable way you can pridict that yours would do the same as mine. again to many variables. i dont remeber what you where useing. but in my first grow i used 1000 w HPS from start to finish. that alone will be all the difference in the world. see what i mean by variables. what if i had fucked up my ph and locked up all the nutes for a week. that alone would slow growth, what if my room temp is 90f and your is 75f. that would change every thing.
in closing i would suggest start small. and take notes of ever thing you do on a daily basis. dont go blow a bunch of money just yet. IE: expensive seeds, 1000w HPS. read and learn what the perfect condition of a grow room should be, and do your best at replicating those conditions. once you do this get a grow going with some bag seed to learn on. i cant tell you how many seeds i have destroyed in the year i have been growing. many of them expensive seeds from RIU/nirvina.
last thing i want to tell you is search RIU for grows like yours. see what they are doing. mimic success. go in these journals and ask questions. do your home work first, i found that there are many people here that will help you, especially if they can tell you did some research.
o yea check out the tutes here before you go out and spend any more money on the super duper bubbler from big name grow company. i made that same bubbler for about $20. made the power cloner for about $50. check out my grow to see them. the cloner is in the tutes. havent been to RUI for a long time. maybe i will have time to post my current grow soon.
again good start and keep the pics coming. we are all pic whores man!!!!!!!!!
