    Final flush

    Flushing isn't considered to be good practice any more. Although there are people is the cannabis growing community that swear by it, the benefits of it have been largely debunked by various scientific studies.

    Were grow lights at one time referred to as a "spider"?

    I am fairly old and have never heard that. Do you have a link to the podcast?

    Day 28 leaves going light and some yellow help

    You are quite right, Plant Magic CalMag isn't for the Oldtimers Organic. If BioBizz CalMag has no N, then it is most likely already made with Calcium Chloride. It is worth doing, I bought a 1KG bag from Amazon, for £9.99, about 18 months ago and I still have most of it left.

    Autoflower topping

    In my experience you don't top Autos because of the loss of veg time. When you top a plant it will take a few days for it to "recover". With a photo-period plant that makes no difference as you govern when the flowering process begins. With an Auto, that is going to start to flower after...

    Day 28 leaves going light and some yellow help

    No I have tried it with a compost/coir mix, not coir on it's own. He thinks pre-made cal-mag is silly because you can buy enough Epsom salt and either calcium chloride or calcium nitrate to make about 1000 litres of cal-mag for under £10. What you are paying for with pre-made cal-mag is the...

    Anyone know whats going on?

    It looks like you might be over feeding. Super dark and shiny leaves, with burnt edges, too much nitrogen. Also, they aren't ready for harvest.

    Deficiency? Chlorine from tap water?

    I tend to leave my tap water sit. Not because of Chlorine, because of temperature. I like to let the tap water equalise to the ambient temperature of my grow space. If you pour icy cold water straight on to the roots, it will shock the plant. But only in the Winter, in Summer I can just use...

    Left grow light on for 24 hours. 18/6 normal schedule

    I am using a Raspberry Pi Model B with a couple of cheap USB Web Cams hooked up to it. It uses a CronJob to take the pics and copies them to my home server. I was using a Energiser smart camera via Google Assistant and Google Photos, but I share my Google Cloud Storage with my wife and kids...

    Day 28 leaves going light and some yellow help

    That is a real interesting read. I used Plant Magic a few years back along with Bio Bizz soil and it was OK. Then, in the first lockdown, I couldn't get it. So I looked at the Wife's Jack's Magic and Tomorite. So I used to pot up twice in veg and then into the final pot just before the flip...

    Day 28 leaves going light and some yellow help

    I have only ever used the Plant Magic Old Timers Bloom along with the PK 4-8. The Bloom is NPK 3-5-4 and the PK 4-8 is NPK 2-4-8. You should be using the Bloom and the PK 4-8 together.

    Day 28 leaves going light and some yellow help

    I am not using Plant Magic soil, but I am using their nutes at the moment, I have just changed back to them and I used them for a long time before. I have never had a problem with them.

    Left grow light on for 24 hours. 18/6 normal schedule

    I have setup CCTV in my tent, with night vision. I have it upload a snapshot, every hour. If you load the pictures in a slide show you can physically see them grow, if they have a period of dark you can see them slow down. It is the first time I have run them 24/0 and I am so impressed with...

    Apical Growth

    The UK is an Autocracy. We have a head of state that no one elects, an upper house that no one elects and a government that is elected by a minority. Unless the ruling classes suddenly all become stoners it will always be criminal. The only way it will become legal is if the ruling class can...

    America has the weirdest laws in the world, I don't get how it can be legal in one state, yet not in another. TBH I could just go and work in the Netherlands.

    Left grow light on for 24 hours. 18/6 normal schedule

    I run mine 24/0 in veg. I used to be 18/6, but with 24/0 you can see the difference in the growth.

    Cal/mag deficiency? Or what?

    Get an EC pen. They are pretty cheap on Amazon. They should do EC and PPM.

    It is my dream to be able to run and stock my own Amsterdam style coffee shop, in the UK. But it'll never happen whilst we are governed by the "school tie" brigade and boomers are allowed to vote.

    Newbie grower, don't know what's wrong.

    Yeah, roots don't like light.
