This is my first time growing, so bear with me. I'm 7 weeks into flowering and the buds were looking very nice. I was just about to start harvesting one plant (i have 4 total in flowering) when I noticed that all but one of them started growing new white hair tufts on the sides of some of the buds. I was just wondering what this means, should I just harvest now anyway? Did my friend who also grows contaminate them with pollen? Or should i just wait a little longer for these new hairs to also color up? I tried the best to include some pictures, but they're from my camera phone, so i hope you can still see what I'm talking about.

dude you have a while to go! Thats waht happens its called a second growth spurt and this is the growth spurt that puts tons of thc on the bud as welll. they will glisten more and more. I would say that you have 3 weeks left.. But if you wait you will get so much more yield and better bud good luck

Whew! That is good news indeed! Thanks a lot!

its the plants last gasp at trying to produce seeds its a sort of safty massage tying to prolong life so that another genoration can be born some times if you leave them to long they will grow balls to reproduce with them self it's the way nature works trying to keep the speasices alive, it sounds to me that you are past the best time to crop if you start to get new bud. have a look under a loop to see what color the trichomes are will give you a better idea. the new bud growth will not yeild much more bud than you have now infact it will be less potant and the longer you leave the plant the less potant the older trichomes will become by the THC braking down to less psychoactive chemicals such a CBD's CBN's ect..

The calyxes look pretty swollen to me; it's time to harvest. I would expect any new growth to be caused by nitrogen.

?? when most people flush soil the last 10-14 days? and cut down on N when going in to flower?obviously you have never read cannabis botany by Robert Connell Clarke.

WTF does "most people" have to do with FutureTron's plants?

i agree with everything except the "tons of thc" part. this will increase your weight by several g's per plant, well worth the wait.

have a nice day

its what happens when you over grow your plants they start to grow new buds in almost everyones plants that grow if you leave them to long they will grow new buds, even when the plant looks like it about to die, its fuck all to do with N as most people do not add N in flower and infact they cut down on using it and flush the pots with plain ph'ed warter 10-14 days before harvest so how the hell do you say the new growth is to do with N??

Peak Floral Stage
Elongation growth of the main floral stem ceases at this stage, and floral clusters gain most of their size through the addition of more calyxes along the secondary stems until they cover the primary stem tips in an overlapping spiral. Small reduced mono-leaflet and tri-leaflet leaves subtend each pair of calyxes emerging from secondary stems within the floral clusters. These subtending leaves are correctly referred to as bracts. Outer leaves begin to wilt and turn yellow as the pistillate plant reaches its reproductive peak. In the primordial calyxes the pistils have turned brown; however, all but the oldest of the flowers are fertile and the floral clusters are white with many pairs of ripe pistils. Resin secretion is quite advanced in some of the older infertile calyxes, and the young pistillate calyxes are rapidly producing capitate-stalked glandular trichomes to protect the precious unfertilized ovule. Under wild conditions the pistillate plant would be starting to form seeds and the cycle would be drawing to a close. When Cannabis is grown for sinsemilla floral production, the cycle is interrupted. Pistillate plants remain unfertilized and begin to produce capitate -stalked trichomes and accumulate resins in a last effort to remain viable. Since capitate-stalked trichomes now predominate, resin and THC production increase. The elevated resin heads appear clear, since fresh resin is still being secreted, often being produced in the cellular head of the trichome. At this time THC acid production is at a peak and CBD acid levels remain stable as the molecules are rapidly converted to THC acids, THC acid synthesis has not been active long enough for a high level of CBN acid to build up from the degradation of THC acid by light and heat. Terpene production is also nearing a peak and the floral clusters are beautifully aromatic. Many cultivators prefer to pick some of their strains during this stage in order to produce cannabis with a clear, cerebral, psychoactive effect. It is believed that, in peak floral clusters, the low levels of CBD and CBN allow the high level of THC to act without their sedative effects. Also, little polymerization of resins has occurred, so aromas and tastes are often less resinous and tar like than at later stages. Many strains, if they are harvested in the peak floral stage, lack the completely developed aroma, taste and psychoactive level that appear after curing. Cultivators wait longer for the resins to mature if a different taste and psychoactive effect is desired.
This is the point of optimum harvest for some strains, since most additional calyx growth has ceased. However, a subsequent flush of new calyx growth may occur and the plant continue ripening into the late floral stage.
