When do you see noticeable buds?

simple answer.... over the next 8 weeks. you will notice it more after the 4th week and on then on..... you've just reached the end of stretch now you will see that stop and flowers start to grow

Mr. Ganja You are my weed phyician, always there when this noobs got a question Thanks!

like above, but just one thing make sure u keep up with the watering/feeding during flowering, as them sativa dom in them pots will be very thirsty

I have really started to notice that, on the tall one above I have to water him almost twice a day to keep her happy, Also I've been feeding once a week for 2 weeks should I just slowly start to increase feeding? The guy at the hydro store said the fert was very potent and to watch close when feeding

ye cause you can keep the dose low, no more then half strength, its rare i go that high, but increase the amount of feedings, not the strength so start with 2 a week during week, the try 3 for week 4, then for end of week 4 to end of 6 try water fed water fed, then fro then till harvest, work back down ect water water fed/ then/ water water water feed, till you're just on water for the last 4 to 7 days,

also in them pot running high ec/ppms will cause over fert issues, its always beter to feed low when growing in smaller pots were there might be root bound issues, its not a big deal, just keep them watering up you will be fine
