Hi Guys, Im currently 7 weeks in harvest on my first crop, 2 white widow,3 jack herrier... i have a small closet space for growing and was using a fan/dehumidifier to try and keep the temp/humidity down up until now.. i checked my buds for THC today,and im worried that there isnt enough as there shld be at this time, 1 week before chopping.... opinions please,experienced heads......... thanks in advance
I don't really know, but it could be related to the burn these plants have suffered. What and how much have you been feeding em?
i dont' know what you mean, but if you don't think they are ready, then dont' chop em until they are...don't harvest by the callender, look at your plants, wait for them.
i have been feeding them optimum grow and then optimum bloom fed them twice a week, til 6 weeks harvest, now just water should i raise the light ?, its aroun 14 inches frm the top ?..... so i can leave white widow in for 10 weeks or so anyway right ? thanks guys
those look pretty nute burned to me, and i'll bet thats a big part of the problem. what type/size light do you have on them?
From what I hear, you should stop feeding it nutrients and co2 two weeks before you harvest and just let it have fresh water.
When you say 7 weeks in harvest, do you mean 7 weeks since you planted the seeds or 7 weeks from another starting point?
threepac: yeah mate,thats what ive been doin....hopefully they turn out ok ? all this time,id atleast like a nice smoke you know ! haha
to tell u the truth it doesnt really look that bad, although they could prolly go a week or 2 longer at least, take a look at the trichs they should be about 50% cloudy 50% amber. when u say 400w what "kind" of light is it; hps? alot of plants get nute burn at the end of there life, theres not much u can do...
i was gonna make a thc ommiter tommrow to try and bring out the thc, anyone think thats a good idea ,given that there 7 weeeks in harvest already ?
That explains it, It will take longer to mature with MH, and the MH is hotter so you might want to raise it some. Just get a mcroscope from radio shack and check the trichomes with it.
Well, I believe that most of the potency comes from reactions during drying/curing. Look it up a bit. Also I agree that they'll probably need to flower a bit longer because you're using a Metal Halide lamp.
dude... im in the 400 club too.. (400w mh) GET THAT LIGHT UP!! 3-3 1/2 feet is optimum there has to be alot of heat coming down on ur plants at 18 inches away...
3 1/2 feet is way too far away for a 400. i've got one and the tops are 8" to 10" away sometimes closer and i don't have an air-cooled reflector. i do, however have good ventilation and air circulation. somewhere on this forum someone posted a guide that shows light effectiveness relative to distance. if my memory serves me correctly it goes 400w hid 6-12", 600w 10-18", 1000w 16-30". imho (but i'm no pro at this) that far away will really effect your yield, quality and thc content.
