Hi guys I posted pictures not long ago of my leaves showing what turned out to be a sign of calcium deficiency. I bought calmag and started foliar straying in the dark cycle and they're not showing signs of improvement. In fact, they're much worse. This is what the majority of the leaves look...

About 5 or 6 here and there out of >100 for some reason. NFT system, 5.7 ph and nutrients fed as per the instructions (CF level normal but on the upper end). Is this a nute deficiency or nute burn? Or something else? Humidity is 60% at the most, almost 2 weeks into flowering. Any help is...

Hi guys I'm planning on having this kind of set-up soon and I'm wondering how you think this might work in terms of heat in a room of about 4.5m x 2.5m squared. I am worried about having the exhaust vent of the air conditioner hanging out of/pointing towards the window but I'd like other...

I'm considering a 1.8kw grow set-up but I'm worried about the heat issue. I understand a decent air conditioner would reduce a standard room's temperature considerably and consistently, but I'm not sure about the temperatures created from an A/C's vent hose if I were to have it hang outside the...

My last grow was a failed attempt at a scrog. I didn't achieve the yield I'd hoped for. This time I'm prepared. 1.2m2 tent 600w HPS + 5" cooltube 5" extractor fan + carbon filter 1.2m2 scrog mesh Strains are Tutankhamun, the highest recorded THC strain I could find (33%) and Super Bud from...

I want to share a transcription of a lecture about free will and determinism. It's one of the series of lectures you'll find in Professor Patrick Grim's course, "Philosophy of Mind: Brains, Consciousness, and Thinking Machines". Discussions like this represent some of the most important elements...

Immediately after separating the buds from the main leaves and stems, you'll find that ~15% of the wet weight is indicative of dry yield, with ~3% variability. Source: Green House Seed Co's Grow DVDs Recently a certain seed company have provided several comprehensive grow videos of their...

Harvest is just around the corner and having put in 150 from a total of 450 spent to get it going, what %age of the grow is a fair share for my associate? The yield I expect will fall somewhere between 300g and 500g since it's a 600w grow. Based on what I'm drying right now, I'm fairly certain...

Thought I'd try and create some dialogue on this. Does the slow drying and curing process provide any significant improvements to the psychoactive potency of cannabis? There are also other things I've never understood, namely taste and "harshness" of quick-dried vs. slow-dried weed. I notice...

Hi guys I'd like to hermie a female auto so I can produce my own feminized seeds (yay!) I understand autos don't stress out much in terms of light exposure. How can I go about effectively stressing one to the point of self reproducing? Thanks!

I'm considering upgrading to one of these systems and I'm frustrated by how little google answers my questions on nutrient levels and how to top-up or replace the water/nutrient solution. If you were at week 1 of 12/12 and added 800-900 ppm of your nutrients to the water for the first time, how...

So yesterday my ballast decided not to work, causing me to worry about the potential shock it may inflict on my plants. Instead of 12 hours of darkness the plants received 30 and now I have to figure out how best to return to 12/12. Does anybody know the significance this has on flowering...

Hi ppl, it's one plant under a 600w HPS 120 x 70cm area (ish) 7 weeks veg, 31 days into flowering so far Canopy's somewhere between 1.4m and 1.6m tall now I've already pulled off a lot of lower branches and leaves but should I remove more? May have to look close to see the lower foliage...

Yesterday: Today: 32 days from seed. Hand watering 3-4L/day atm. I've highlighted the current main tops. Since the above picture was taken, I've tucked some fan leaves under the screen so all of the tops can grow up and longer. Am I doing it correctly? Any feedback's appreciated...

Hi guys, Advanced Nutrition are seemingly straightforward in their instruction for Sensi Grow A & B (use 4ml/L of water), yet after reading multiple threads where people have no idea what they're doing, it became somewhat unclear to me... I have some large plants in their vegetative stage. If...
