I know this may not be directly related to the topic at hand, but I feel it must be addressed. It's frustrating to see people argue over whether cannabis is a weed or not, when both sides of the argument have it completely wrong. Definition: So cannabis is not "just a weed". Every plant can...

It's almost certainly nitrogen toxicity. Too much nitrogen will cause leaves to have a deep green color and the tips to curl downward (aka. ram horn). Too much heat, on the other hand, will cause leaves to curl upward. The outer part of the leaf dessicates faster than the inner part causing it...

Too much light. You forcing the clone to photosythesize when it doesn't have the root system to provide water and nutrients to the leaves. I've gone through it before. I had a bunch of clones under a 96w 4-bulb T5 and it was too much for them, they all started to wilt. I simply put a paper towel...

So you are using a balanced nute, then throwing that balance off with PK13-14. Try using the nute by itself for a while and see if that changes things. Please read Uncle Ben's, "The never ending abuse of phosphorus in flowering" article. It's on RIU somewhere, give it a search. I've never used...

Definitely way too much nitrogen, no doubt about it. I had the same problem with one of my mothers that I have in the same type of soil (with osmocote pellets). Just flush out the soil with 2 or 3 gallons of fresh water and that should do the trick. Don't bother trying to get the pellets out...

I use a 1:1:1 ratio of GMB for veg, and the Lucas formula (0:1:2) for flowering. Works like a charm.

Kill it now and start fresh. You could havest the pollen and store it. I think it stores in the fridge for 4 or 5 weeks. That way, when you get a female, you can pollenate her and get hundreds of seeds for future plantings :) To answer your original question: Depends on whether it's a...

In order of importance: 1. Experience (Learning how to read the plants needs and respond correctly, aka. developing a green thumb, and learning techniques that work) 2. Knowledge (Not only in aquiring information, but being intelligent enough to thoroughly understand it and apply it as well)...

Man, you don't need any fertilizer at this stage. The Shultz potting soil has plenty of nutrient in it for at least 4 weeks of growth. It looks like you have thrown off the osmotic balance of the plant (eg. water is flowing out of the plant instead of into the plant) which is what is causing the...

Lol, hilarious. Thanks for the early morning chuckle :) I have to agree with 561crim on this one. You aren't going to "revolutionize" anything with this "idea". You think if you could impart flavours in plants that way, the commercial produce industry wouldn't have already done it? Come on...

Sure. Tomato plants are very similar to marijuana plants when it comes to nutrient requirements. Go for it.

Then why ask? You obviously realize that nobody can possibly estimate what your going to yield based on the information you provided. There are so many variables that can affect yield that it's impossible to estimate. You know this, yet you still ask?

I reuse my hydroton and all I do is the following: 1. Remove the rootmass (with the hydroton) from the pot(s) and shake vigorously over an open garbage bag until most of the hydroton has fallen off. You may have a 20 or 30 balls left in the rootmass, just throw them out, not worth the trouble...

It's dew. During the light cycle, your plants are transpiring (releasing water into the atmosphere), but the humidity doesn't condense because the temperature is high enough to hold the water (As air temperature increases, its capacity to hold water increases as well). However, once the lights...

I agree, it's definitely nitrogen toxicity. Dark green leaves that look like a ram's horn (or a canoe) is the tell tale sign. What people seem to forget when talking PPMs is that nutrient ratios are also a factor. If you give a mature plant 1000 ppms of the correct ratios of N,P,K,S,Mg, and Ca...

I use AN 3-part and have found it to perform as expected, nothing spectacular or anything, but it works. Actually, if you look at the nutrient ratios and derivatives, AN's 3 part is identical to GH's 3 part flora series. It seems that these two formulas are exactly the same. I have nothing bad...

I use AN 3 part with R/O water and depending on the concentration and the ratio of grow, micro, and bloom I use, I usually end up with a PH of between 5.5 and 5.7 everytime. I will usually add a ml or two of potassium hydroxide to raise the PH to around 5.8. My system is drain to waste, so once...

Yeah, I agree. Too much water. At this stage, one irrigation per day is plenty.

Interesting question. I would say YES, it makes sense, because when you clone a 6 week old plant, the clones are effectively 6 weeks old, once they are ready for vegetative growth again, they'll probably be close to 9 weeks old. So chronological age continues on into the clones. However, I've...

There is no debate, argument, or "war". Both CFLs and HPSs can be used to grow, they are just used in different applications. When space, cost and heat are limiting factors, then CFLs are more suited to the task, but for optimum growth and bud production with no other limits, HPSs are hands...
