flowering booster

I got some Jack's blossom booster it has

10 30 20 npk does this sound ok for my bubbleponics
I got it because my girls were not flowering that much and i thought the high Phosphorous
would be good to kick it into gear
5 weeks no serious flowering

I just added the booster yesterday. But before that the hairs are coming out every where, toward the top is where the main stock nodes are opening up now, but the nodes further down are taking there time. im at 7 weeks now


blossom booster

its says for outside plants put a teaspoon for every gallon and 1/2 a teaspoon for inside plants. which would i consider my plant i know its inside but you know.

I see you been growing since May 2009, that is longer than I have been growing. But honestly looking at your plants I see leafs that are ok, leafs that are droopy and heat battered. The stems on the shot there look weaken and this all points to high temps in the room, is this what is happening? I am just trying to figure out what is going on, 7 weeks in flowering my girls at 5 weeks have solid colas forming already and I use SBA, SBB and Carbomax for 30 dollars total flower nutrients I am running. Last run my girls did the same thing, all different strains and again I was using cheap nutrients.

what is a good temp for the girls and what is a good humidity as well

the hottest it has gotten in my room is 99 or 100 degrees and maybe 55 or 60 humidity

72F maximum lights on, 10 degree drop in temp at lights out appreciated but not necessary. Humidity is something I have tried to do a lot of research on and the best I can give you is 50% in veg, 60% in flower maximum and as far as I understand humidity is very important in flower so minimum of 40% is what I used. I run C02 now and I run 60-80% humidity and 85F lights on, 65F lights out a 30 degree drop in temps. This is to help keep my nutrient solution cold soon I will just do the 10 degree drop when I have a nutrient chiller. I run 1200-1500PPM C02 and 85F you can run higher temps if you have C02 and you actually should. But every strain has magic spots, you might find out yours is cold blooded.. Recap

C02: 78F-82F maximum (I run 85F to combat Powdery Mildew in my area, some run 90's with C02)
No C02: 68F-72F

Humidity can screw you with mold and etc it is highly dependent on what you area is like, tons of mold, perfect conditions for spores and etc.. So this is a rope you will have to walk on your own. It has always been known high humidity is appreciated by Marijuana, it is the mold we are fighting.

So if i have it in the 90s its way too hott? and is 90% humidity too much?


or do i need to stay calm and make proper botanist decisions like just give my plants a little time.

That all seems way to high. 80F MAX

Yeah MJ plant has a rated maximum temperature of 80F just going by the book, 72F going by the stoners.. At those temps you need less nutrients not more, the metabolism will barely be moving. 90% humidity I am not brave enough to try!!

I've read that temps above 85F will degrade THC, I am not sure if this is the case or how CO2 might play into this (since CO2 will help plants tolerate higher temps). I'd be interested in hearing the input of others with experience in this area. I have my AC set to kick on @ 83F to be on the safe side, and I run CO2. My lights out RH is set to 50% and my daytime is 58% - humidity is controlled via intake / exhaust fans connected to a greenhouse controller. This is all in my flowering area, for the record.

Both high and low humidity will dramatically slow transpiration - especially if you're hitting 90%. I agree with Mejuana's assessment - you need to get your temps and humidity under control, your plants shouldn't look like that at 7 weeks. I have used dehumidifiers in the past, but find that good intake / exhaust is much more effective, and kinder on the electrical bill.

waite slow the metabolism? the damn thing is growing like crazy and is almost too tall. I mean i do value every ones thoughts. but the damn thing keeps on getting taller. am i looking at it wrong or will it not flower at certain temps, will it just keep on vegging?

It will grow still, but more slowly - the high temps are making it stretch.

If I can use a crude analogy - you don't see many 5'4" 450# people living in Zimbabwe, nor do you see many 6'6" 150# people living in Fargo.

nah i like crudeness, favorite kind of comedy

But what about 88 degrees and 40% humidity, i had to take out a light, i have 7 going from 8
6 200 wat equivalent and one 150 equiv

ya i keep my flower room about 77 degrees with 55% rh.with an air cooled 1000w hps and they love it.i used to have temps that would get into the 90s during the summer and the would look nute burnt and grow all shitty

Because that is a natural defense mechanism the plant is trying to survive, she doesn't have a lot of options.. hehehe
