Looks like a sandfly, they don't seem to harm the leaves or buds but i notice their larvae (little white worm like things) in my root zone and i'm not sure how much of an issue this is. Plants are 7 weeks into flower, and look like they have another week or two to go.

Just took these on day 49 of flower. No idea what strain, just got some hold of whatever clones i could. Unless you buy from a professional seed bank nobody really knows what they are growing. Can't be too bad though, some of the colas are the size of coke cans and there's still a few weeks to...

I decided to do this because i often find myself looking at my previous grows to see how im doing, and so ill probably regret not doing the same with this one. So today marks 6 weeks exactly from when i switched to 12/12. Im pretty happy with how its going at this point. The cola's are of a...

Ok i have been browsing this forum a long time and if there is one thing i have noticed that really annoys me it's the amount of absolute rubbish that is spouted on almost every single thread i read. Its not just these forums, its all of them. I see legitimate questions being asked, and then i...

As the title says. I about to enter the 7th week of flower and its all going pretty good but one thing i have noticed is that the buds slightly lower down are much more frosty than the buds directly under the lights. Is this normal? Or is it possible that my lights are too close? I do not have...

Up until now, i always assumed that if someone said their plants were 4 weeks into flower that they meant 4 weeks into the 12/12 phase. Apparently there are people who consider the flowering phase to begin when the flowers actually start to appear. Am i the minority or majority here? Which...

Im pretty sure its ok, but just want to check. Day 31 of flower (week 4.3). Strain is unknown.

My plants are 3 weeks into flower. They are looking pretty good, but after noticing that they were starting to look a bit off over the last few days i did a soil water runoff test and the pH was at 6, possibly even a bit lower. Anything that goes into the soil is always pH adjusted to around...

My light cycle is currently 8am to 8pm and i need to switch it to be on at night and off during the day because the days are getting too hot. To switch i need to have one of the periods go for 24 hours should that be the day or night period? Im guessing night?

I've been using a 600 watt HPS from start to finish with my last few grows. I've decided to upgrade to a 1000 watt HPS. In the interest of cutting power costs, i want to do future veg cycles under the 600 watt and then use the 1000 watt for the flower cycle (given that during veg, the lights...

This one confuses me because i am growing in the exact same environment as the many other successful grows i've done. They are about 2 weeks old, from clones (nice healthy looking clones they were). The temps are fine, the lights are fine, i havent fed nutes yet and am using the same soil as...

I'm having trouble figuring out whether this is mould in its early stages or not. These are 60x close up pics of a leaf which looks like it might be going bad. Is this mould or something else? I've seen cloudy trics but these are extreme, and they appear to be sinking into the leaf.

According to http://www.cannabisculture.com/articles/1536.html "Plant internodal length is directly related to the difference between day and night temperatures; the warmer your day cycle is as compared to your night cycle, the greater your internode length will be. The opposite also holds...

I know its normal for the fan leaves to go yellow near the end. But as you can see, these are not fan leaves, and they are not just going yellow. There are also brown dead spots. No idea what strain. Soil grow, i am highly suspicious that it is heat stress (there are a number of reasons which...

I just got my new usb microscope thing so that i can use it to harvest my own crop at the best time. Looking at this bud i got the other day, would you say this had been harvested too early? There isn't much amber, and some trics have little amber centeres but the rest cloudy. Do they count as...

These pictures were taken 6 weeks (exactly) of flower. Fairly certain it is nute burn - however, the problem seems to have not improved since flushing. With at least 2 weeks to go, i can't afford for this to get too much worse especially since its effecting the small leaves coming out of the buds.

I had a quick search, but i don't really see how people keep their co2 levels at XXXXppm. Is there some kind of device which measures co2 levels in the air? Do these devices hook up to your co2 regulator to control the release?

Has anyone ever experimented with keeping temperatures at a constant level through the whole grow? I've been reading up, and there seems to be good reason to suspect that the recommended drop in temperature during the dark period is nothing but a myth based on the fact that with outdoor...

So i decided later on to create a grow journal. I'm going to start this at week 2 of flower. These plants are clones about 1 1/2 months old. LST'd heavily while they were young, and as a result i now have this beautiful somewhat even canopy (not as even as i'd liked, but still 10x better than...

Adding one teaspoon of epsom salts to 3 liters raises my ppm quite a bit. Is it ok to rise much higher than your normal ppm with epsom salts if you're correcting a deficiency? I'm adding the salts with my normal fert mix because i have large pots and they only get watered once every 4 or 5 days.
