I don't think it would easy to overdose a plant on vitamins as the plant could only take them up through its roots at its standard rate of absorption,its not the same as nutrients all though i don't know this for a fact.

Do you use a hydro nutrient of vit b or are you just adding something that contains vit b?

I'm using a product called B52 by Advanced Nutrients. I also use superthrive if I haven't got any B52...

I follow the advanced charts... to a degree. I look at it like they know better than I do about the right levels of nutes. I don't follow the charts exactly as they are based on an 8 week flower schedule... I'm also fairly experienced enough with them now to make calculations based on varying factors.

Like I said, the guy said I was wasting my B52... yet he couldn't explain how HE knew better than a company with a team of scientists NASA would be envious of. He's had me thinking though since... but what I've found is that the more nutes you give, the bigger your plants get.

Yeah definitely finding your type of plants max tolerance levels for nutes will improve your yields.
Your friend may be thinking that what your adding is wasted as the plant can only take up so much as to be useful in the allocated time.
My theory is to see what works and what doesn't and then stick to it and ignore the rest.

Some strains can tolerate exceptionally high levels of nutes and even toxicity whereas others would be dead in a few days.
Basically if you can see that it works for you do it or use a test plant which is what i do each grow i have one test plant that i feed all sorts of crap to.
As an example BigBud would probably grow in a couple of dog turds whereas say Blueberry would probably die within days.

At the moment im experimenting with mixing miracle gro and tomato food with molasses,so far i burnt the plant a little bit lol.
I have to slightly lower the miracle gro i think but i have noticed that all though i burnt the plant the crystal development is very high.

I grow in coco coir and perlite 60/40. coir is an excellent ph balancer, it absorbs many of the excess salts left over from heavy nute schedules. My strain is also chronic, at least in growth behaviour, as it is crossed with white russian which plays more a part in the high.

Also, since growing in coco I'm sure the taste of my bud has improved. It reminds me of soil grown bud... but you get all the advantages of hydro. If you're looking for a soil replacement, coco would be a great choice. It even looks like soil.

I may one day try hydro but for the foreseeable future i am going to stick with what i know.
Hydro seems like such a hassle and initial expense to me,but that may just be my age showing through.
Did you cross the chronic x wr yourself and have stabilised it as seed or are you cloning the best?

not mine... I wouldn't know an f6 from an f1. I just clone. The guy i got them from is a breeder though. This strain should end up in the shops soon. Not sure when, or what it will be called yet though.

ive read that useing 24 hour veg,gives you a 15%increase over 18/6,but you are useing 25%more power,so if power and money is a consideration,then 18/6.

I'd like to see the source, i read a ed rosenthal column where he said you lose 25% of growth from running 24/0 and it works out cheaper because for every month you veg you lose a weeks worth on 18/6 and all other costs remain static like rent and everything else.

18/6 is actually more expensive in the long run

im a one finger typer jorges grow bible page 175 pot can efficiently process 16 to 18 hours of light after which it has deminishing returns,also a study in hight times but thats 80 mags i read so to find the story would take a weekend.but it doesnt really matter its about preferance in the end.

I've got a jorge cervantes book and to be honest i've read through it and I question a lot of his "facts" but ed rosenthal I will take his word every day of the week.
