HELP needed,6th wk into Flowering

heya peeps,need help baddly,i thought ive went through everything but into 6th week of flowering master kush,2 1000watt hps,,fox farm nutrients,70degrees,50percent humidity, 6.6 ph water,airflow,and im still getting small airy buds and this is supposed to be high yeilding,,please any info is appreciated, i uasaly grow purple diesel and was having same problem with that strain also.thx

How far is ur light from the tops

everything seems to be spot on. check your nutrient regimen. master kush a 10wk strain??? youll be amazed on how much they plump up in 2-4 weeks.

What colour are those leaves in the first pic?


They look purple!

I started flowering a master kush on 4/14 and she seems like a slow developer. 600w, ffof, tiger bloom. The purple leaves are curious though, have you been fighting any deficiencies or lockout?

is that 70F ? with light`s on ?

15" some r 10"

was over ph ing the water before in soil but ive used sledgehammer to unlock nutrients just about a week ago but that was first time i used flush i uasly oly used water so maybe i had previous lockup?

ya 70 sometime 68 ,10deggree differnce at night,,is it to cold ?

maybe purple because its colder maybe than it should be ? havnt seen alot of concrete info on some info of this strain

Purple could also be Mg deficiency. Check the stems and such - if there is purple streaking then it could be deficient in Mg.

Other than that, yeah it's a 10 weeker. Give it some time.

Colder temps have bben known to change the color

Not only this but also known for slowing growth.

How r u running 2000 watts qnd staying qt 70 degrees?

Ac works wonders i guess lol and i have a evap cooler goining on bottom of canopy where i can move it around like a portabl;e fan ,,but ty guys MG makes sense to me so hopefully that will make things look better,,ty for all the remarks realy appreciate it ;

optimal temps is between 78F and 84F

Dam ok that"s a big difference ill definatly heat it up ty bro i appreciate it,only about 4 yr grower so im learning everything still lol..

no problem

and no offend, but 4 years of running 2x1000W and you did`t read the fist pages in any of the 1000ish grow guide`s out there ?



[h=1]TEMPERATURE - Cannabis Growing Guide[/h]Proper temperature is one highly variable factor. Most books state optimum grow temperature to be 70-80 degrees, but many list extenuating circumstances that allow temperatures to go higher. Assuming genetics is not a factor, plants seem to be able to absorb more light at higher temps, perhaps up to 90 degrees. High light and CO2 levels could make this go as high as 95 degrees for increased growth speed.* An optimum of 95 degrees is new data that assumes very-high light, CO2 enrichment of 1500 ppm and good regular venting to keep humidity down. It is not clear if these temperature will reduce potency in flowers. It may be a good idea to reduce temperatures once flowering has started, to preserve potency, even if it does reduce growth speed. But higher temperatures will make plants grow vegetatively much faster, by exciting the plants metabolism, assuming the required levels of CO2 and light are available, and humidity is not allowed to get too high.
With normal levels of CO2, in a well vented space, 90 degrees would seem to be the absolute max, while 85 may be closer to optimum, even with a great deal of light available. Do not let the room temperature get over 35 C (95 F) as this hurts growth. Optimal temperature is 27-30 C (80-86 F) if you have strong light with no CO2 enrichment. Less than 21 C (70 F) is too cold for good growth.
Low temperatures at night are OK down to about 60 degrees outdoors, then start to effect the growth in a big way. Mid 50s will cause mild shock and 40s will kill your plants with repeated exposure. Keep your plants warm, especially the roots. Elevate pots if you think the ground is sucking the heat out of the roots. This is an issue if you have a slab or other type of cold floor.
As temperature goes up, so does the ability of the air to hold water, thus reducing humidity, so a higher average temperature should reduce risk of fungus.
Contrary to many reports, high humidity is not good for plants except during germination and rooting. Lower humidity levels help the plant transpire CO2 and reduce risk of molds during flowering.
Studies indicate the potency of buds goes down as the temperature goes up, so it is important to see that the plants do not get too hot during flowering cycles.
