Looks like you've got something eating the leaves, as VaporTrail said. Those pictures aren't the result of nute burn or anything like that (although some of your leaves look really dark green, which may be a sign of a bit too much N). Try some neem oil if you're trying to stay organic (though...
Foco! I'm probably pretty like-minded in that I love and adore weed and everything about it, but I'm still figuring out this growing thing and am not worthy of popping any beans like those with my cheap little 12/12 from seed, florescent set-up. I do have a ton of mutt seeds from bags that I'm...
In case anyone's watching:
Bruce Banner mutt, just starting to show pistils, and still tiny:
Darth Maul mutt, 5.5 weeks into flower:
And, just to show off some more, cause I think she's pretty, Sour Grape mutt:
Cheers!
I'd probably say so. 2-7-7 isn't super strong, so a bit extra (say something like 7-3-3 or something similar) shouldn't be enough to cause problems. I'd say to basically, get another fert with a higher N number, and do half that and half the other one you've been using. So, if you've been...
I'm not super familiar with the various brands out there, so no recommendations on the brand, but I'd say get something that's NPK numbers are similar. For instance, some are like 30-20-20 while some are more like 3-2-2. Obviously, the first one is 10X stronger than the second, which would...
That does look like some sort of toxicity. Too much nitrogen or potassium, would be my guess. What nutes/medium are you using?
Either way, it also does look like it's affected your bud production, as those are pretty small for 4 weeks.
Critical hit it. Those popcorn buds go from being a bowl's worth to fat little nugs, so you'll be sacrificing smoke in the long run. Besides, many of the trichs are still developing, and not yet full of goodness.
But, if you insist on it, I have quick-dried by putting a piece of aluminum...
If those are the only leaves yellowing, stop worrying. Could be anything from not getting enough light to accidentally getting wet with nutes while you were feeding the plants and not being rinsed off, but in any case, if it's just those first leaves, you're probably fine.
Could be a few grams, could be a few ounces. No way to tell at this point, as there are so many variables. But, this might help: http://en.seedfinder.eu/strain-info/THC_Bomb/Bomb_Seeds/
1. That's one happy plant! Looks great!
2. It usually takes a week or two for the pistils to start showing up.
Unsolicited advice: You'll want more light than just a couple tubes for flowering.
Cheers and happy growing!
This is kind of what this site is dedicated to, so perhaps read up a bit more about the basics, then ask specific questions. That's probably more likely to yield better and more helpful responses.
Cheers and good luck!
