General Cultivation Q&A

hey just wondering if anyone has had problems with the tap water mine is 0.8 ec and after a few days with a air stone it drop and flashes between 0.6 ec to 0.8 ec is this very high ? can it cause me dramas? I say this because iv been using ro water in hydroton / clay balls for the last few years and when I went back to cooc at the start of the year clones in small pot they where lush green feed with ro water. then I move house and think I may as well use tap water since I have a friend that grows in the same suburb with no dramas so I went back to tap water and as some know iv had so much dramas it not funny. anyway just wondering if this hard tap water could be my prob…

Just a quick one, three or so weeks to go, starting to keel over! Figure its a deficiency during veg possibly. Using Powerfeed and potash during veg, Powerfeed, superbloom and potash during flower. Lack of silica perhaps? Any ideas?

Hey blades, after a ton of research and weighing up pros / cons of coco nutes, I'm still overwhelmed with the sheer amount of info / bullshit info out there and can't decide on a decent nute line that isn't ridiculously expensive. I've looked at standard lines like canna, CNS, etc. but they all seem to be so unnecessarily expensive (especially due to where I live). I've looked at cheaper powder nutes like dyna gro and jacks classic citrus feed but again, being in australia means somewhat limited options and I can't warrant paying more for postage than the product itself (may aswell go with the super expensive canna then). I've found a brand of fertiliser at a local sho…

Hey all, I was looking for some advise on sexing plants. Mine are currently about 13cm tall and have 4 nodes. When will I be able to determine the sex of the plants? Would pictures be helpful at this stage or will I have to wait until the bloom phase to find out? Any advice would be greatly appreciated

Hi everyone, I'm looking for some clarification on flowering times. If a strain description says flowering time of 9 - 10 weeks is this from when flowering is induced or from when buds become apparent please? I have some SSS Bubblefucks that I thought wouldn't be ready for another 2 weeks or so but most pistils are brown and they are starting to foxtail significantly so I'm wondering whether they could be mature enough to harvest now.

Seen this awesome gadget thought is let you guys in on it. Although a little gimiky pretty cool for a hobby grower "The unit houses four separate sensors that monitor light intensity, ambient temperature, soil moisture and fertilizer levels, with real-time alerts sent to your iPhone whenever a plant needs your assistance. For example, if your plant is becoming parched the app will send you a warning so you don’t forget to water it. Likewise, if it senses that temperatures are too high for a specific species of plant, the Flower Power will let you know before it even begins to wilt." Has 2000 species university in Netherlands worked on the list maybe canna is in the…

Hi stoners, I got a plant from a friend and it is on my balcony for about 2 months, in a pot with soil, no lights, just sun. It has grown to about 50cm and it looks very healthy. Also, I have been reading about growing and I understand this is far from ideal. Also, I have no expectations with a simple setup like this. However, it would be nice to be able at least one joint homegrown. Is there any chance it will put some buds off? Cheers,

hey guys excuse my ignorance but i was told about a product that used to be called 'heavy'. i cant find any info on it. has anyone heard about it? what does it do? thanks
