Critical autoflowering grow (single plant)

Hey guys, I'm a bit late on starting this journal, plant has been vegging now for 3 days under a 6400k 125w CFL, but it had a rough start, I had to use a 125w 14000k CFL as I had no other light to use for the first 2 weeks of it's life. But it's starting to grow rapidly now it's got the correct spectrum. I will be updating this with a new pic everyday so that the progress can be judged and any problems can be spotted by you guys.

I am growing in a converted sub box and I've got about 20 inches of vertical room to work with from the roots to the light so I will have to LST it to keep the height down. The box is about 15" wide so there should be plenty of room for the plant to spread it's wings. I don't have a temp/humidity meter or a PH tester yet, they are on the way so I can't really judge what my growing conditions are like at the moment, but it's been 3 days since I put in the 6400k and the growth has been insane. Anyway I'll leave this pic and let the growing continue! Also I moust apologise for the position the photo is taken in, I only have one hole in the box where the sub goes and it is difficult to take a good shot while trying to not get the light in the pic.

Which critical auto is it? Also in all honesty you're probably gonna need more room.

I'm actually not sure what strain it is, I bought the seeds so long ago. I have helped some friend grow in the past and have grown in similar amounts of space so I am hoping for the best. If I can get anywhere north of an ounce I'd be happy.

im doing dinafem's critical + auto right now its about two weeks from harvest if you want to check out my sig. that plant is going to explode and get super stretchy. but the buds look super dense. but i doubt you'll get close to an ounce. maybe a half or a little over at best im guessing. just judging by what i have right now

I really hope it doesn't stretch too much, I will be LST'ing it shortly to keep it as low as possible but i can't move it if it get's too big.

Any decent growth overnight, the 3rd set of leaves are showing themselves and I picked up some biobizz flowering nutes to feed her tomorrow when she gets watered. I also moved the plant down about 3 inches further away from the light as the soil was getting very hot as she was starting to show signs of heat stress. The PH test kit got shipped as well so I should have that some time early next week and will be able to see the state that the soil is in. Anyway onwards with the pics.

Also does anybody think its strange how the leaves are overlapping each other at this point? I have never see a plant grow this way before.

bro between week 3 and 4 that plant will almost double in size. critical + is best suited for scrog imho, but lst is definitely a must if space is an issue. mine maxed out at two feet but they can reach 3.5 of long stretchy branches with lots of popcorn nugs.

Decent growth today, I gave it about 500 mls of water and moved it slightly closer to the light, it's getting quite a bit fuller and wider but not a whole lot of upwards growth. Also noticed a bit of black crap on the leaves today, I think it might be a bit of soil as I was breaking some lumps up today. Anyway here's a close up pic!

Day 4 of the journal, it's getting quite thick and bushy now, exactly 4 inches high, which kind of sucks since it's almost 3 weeks old now and the bottom fan leaves are starting to try to turn around as you can see in the pic, anyone got a reason for this? Soil is still quite moist after yesterdays watering so I may not need to water it for another 2 days. I just hope it would start growing upwards a bit more than outwards right now, I don't have any way of getting light to the bottom fan leaves as I have buried the plant quite deep in the pot. Anyway I'll leave you with the pic to see her growing progress! Actually could the leaves turning like that be heat stress? Still waiting on my thermometer to arrive so I don't know the temps, but the plant is 6" away from a 125w CFL so it shouldn't be too hot, right?

Lots of growth in the last 24 hours, still not very much vertical growth and the leaves are starting to bunch up on each other because of it, it's getting quite thick but no room for the leaves to go anywhere, got another few leaves in the centre trying to push up that should be developed in the next 24 hours or so so I hope that will give it a bit of a height boost. The fans on the bottom are not recieving much light and may have to be chopped in the coming week depending on how they progress. I think I will give it some nutes and water tomorrow, the soil is getting a bit dry but I don't want to feed it too early and stunt her, making good progress now! According to other grows it should start flowering in about a weeks time, yikes!

Got the plant repotted today, I used the same pot but filled it all the way up to the top with my soil mix, the way it was the light wasn't reaching the bottom leaves and they were wilting, even a few hours of light has perked them up a bit! It's getting nice and thick now, the leaves are still fighting for space though and I took a look at the nodes, they are only maybe an 1/8th of an inch apart which is strange, no idea why there is no vertical growth. I also got some soil on a few leaves today that I can't get out, hopefully it won't do any long term damage to the plant. Looking forwards to seeing tomorrows growth!

be patient buddy that plant is going to shoot right up. besides tight inter-node spacing means denser buds

I fucked up today, gave it way too many nutes and too much water. Oh well, hopefully it doesn't bite me in the ass, I'm not going to to water it until sunday and see how see responds. Also I moved the plant about an inch further away from the lights, it was getting rather close to them and getting hot so I think that's why she is canoeing so badly. Pic taken 5 mins ago!

oO as I found out this is not actually an autoflowering plant, it's photoperiod. I was getting it confused with some old seeds I bought a few months ago. I wonder when I can put it into flowering, maybe a few more days of veg?

I vegged my critical+ by dinafem for thirty days. I'm on about day 35 of flower now and has pretty chunky nugs coming in everywhere. I would say do about the same. The plant is only about 24' tall and has been topped and scrogged pretty heavily. I will probably buy this seed for my next garden too. I had the autoflower version too, but it went hermie about a week ago. It was a much shittier plant this the photoperiod.

mine topped out at two feet. what's yours at?

Yea, before I pulled mine, it had stretched quite a bit. It took it about two weeks to catch up to my photo period. And yes, the photoperiod is better. I think this is true as a general rule in cannabis. The reason I say this is that a northern light auto went hermie on me too. No other plants did though. I am now growing two dinafem; diesel and critical+ and one barney's bluecheese that is just now exploding into flower. All of these photoperiods are much more stable and cooperative than the auto's, in my experience.

Yeah those nutes I gave her yesterday really fucked it up, I don't really know where to go from here, I got my soil PH measuring kit today and tested it at 7.5. I don't have any PH down yet so I just put some lemon juice on the soil in an attempt to bring the PH down a notch. Pic quality is not great but you can see the yellowing and canoeing of the leaves, any ideas on where I go from here to rescue this girl?
