Blue Dream (First grow)

@ThatsNotMe, the calmag deficiency comes with the intensity of all LED and especially quantum boards. Another one to watch out for from week 3 on in flower is phosphorus deficiencies too. It took me forever to figure out what what happening. You can note it by the veins in the leaves starting to turn lighter which will eventually lead to the whole leaf. Just sharing something that took me a year to figure out on my own. The other one I just learned not long ago is that you very rarely see a cal mag toxicity so you don’t have to worry about it very often.

No idea to be honest. I flushed mine so they're not due watering yet but need to give them calcium/magensium due to blurple lights (apparently there's a correlation between blurple lights and calmag deficiency). Here: https://www.growell.co.uk/advice/hints-tips/calcium-magnesium-the-bond-is-strong towards the bottom it says: "If you’ve already got a deficiency, a CalMag will correct it. To correct the deficiency quickly, it is best to apply as a foliar spray at 10-15ml per Litre. This may sound like a lot, but it is safe and will work quickly."

@TheCode, Haha, yeah. That was the plan all along to drop the third one so no biggie. The tent is 50x50x100cm. Tiny! It's my only tent so yeah, it'll have to do for the whole cycle. I feel I could have gotten some small auto instead for my first grow, as Blue Dream can get really big, but oh well. I'll try to manage it somehow and leave enough room for stretch. I'm going to throw a scrog in there and was thinking of topping it only once, let both plants fill the scrog, supercrop the main colas, let it recover and flip to flower.

@TheCode, Thanks man. I'm growing in Canna Terra Professional Plus so not coco. I've dissected the twisted one and I think I was right. Looked like the seed ended up on top of a chunk of bark and the roots never managed to spread in the pot (I'll upload some pics later). I'll be lowering the lights later on as well. I'm kinda winging it.

@ThatsNotMe, So its coco you have yeah? Yeah you should really have PH meter it's like one of the most important things mate. Well you doing everything kinda right so yeah maybe the roots is the problem but that one girl really looks streesed. And by the way those girls start looking a lil bit hungry are you feeding them?

@TheCode, The one that looks stressed gets everything exactly the same as the other two. My theory is that the seedling has hit some chunk of food (bark, etc.) in the soilless mix but I will be getting rid of it later today and will check if that were true. It goes through twice as much water as the other plants. Humidity is between 50 and 60%. Temps are between 20C (night) and 26C (day). Fan's been blowing on them since they were born. PH is one think I have no way checking so it might be a bit high, but it would be the same for all 3 plants. Also not root bound. The one I repotted, the roots didn't even get to the bottom of the pot yet.

@ThatsNotMe, thanks. Afraid this 2nd grow won't look as good with different training method, and a few males.

@buddha61, I've looked at your harvested diary and damn that was satisfying to watch.

@ThatsNotMe, No worries mate

@DILLIGAF, Thanks man. I've accepted another one as an answer as it mentioned something I wasn't aware of in regards to QB. I will be installing them as soon as they arrive.

@ThatsNotMe, Lift it ASAP, you want your plant growing in as high a light level as possible :) it's probably not going to catch up. The load refers to the amperage the diodes get; at (for example) 700mA a LED is more efficient (in terms of lumens per watt, or lm/w) than it will be at 1400mA. Indeed, dimming the driver will reduce the current available to the leds. But that's a whole other subject.

@BillMonroe, Thanks. At which point would I put it on the platform? Can I assume that it's not going to catch up with the bigger one and just lift it up right now? The QB are two 120W boards with 1 240W driver (I went for 2 separate ones because I want them side by side and not the long way like the 240W normally look like). I'm not sure there can be knock-offs of quantum boards as the concept is really simple, driver is made by meanwell anyway so the only difference can be leds. Hopefully Kingbrite and Meijiu install LM301H when they say they do. I know I'm not getting top bin but It's $170 shipped to UK for both fixtures and the driver, including ratchet pulleys and heatsinks. Top bin is probably another $100 on top and I have no way of checking. And in 2x2 tent I don't think the difference is going to matter anyway. I did go for 240W because I've seen on samsung website somewhere that those LM301H are most efficient when under 50% load. Thanks again

@Cannibalgardens, Thanks for the answer. Really chuffed that someone more experienced likes the look of my girls.

@ThatsNotMe, I asked because that is exactly what I was thinking of doing and I thought the same about the 6 inch fan, I was thinking about just putting my filter intent and fan out, but seeing yours ' I'll probably copy you.

@Trip614, It's a 4" filter attached to a 6" fan through a reducer. I'm probably going to try to use it for this and one more grow before replacing it with 6" 30cm one. The thing is, that in 2 x 2 tent I never get the fan on higher speed than 4, but probably will crank it up if I need to reduce humidity closer to the harvest. So the 4" filter kind of works in that small tent, but the airflow is restricted and you can feel it on higher speeds.
