First grow issues

First grow and I’m worried. I mixed up white widow and lowryder 2 not realising LR2 is auto flowering.

My concerns:
1) I’m worried the pots are too small for the plants I think they might be getting root bound and need re-potting.
2) I have a problem plant showing lots of signs (see pictures below) not sure if root bound, magnesium deficiency or just over nutes? PH is 6 but using a cheap device to measure it.
3) Are they going to grow much bigger as the area now seems dominated by plants. Will my grow space cope with them?
4) How much should I expect to yield? This is all for personal consumption and I’m not a heavy smoker (1/8 of an ounce per week). I’m worried I’ve gotten carried away and grown too much.
5) The back left plant is really gangly and different to the rest. Am I right thinking it’s probably a male? If so I was going to rip it out but at that size is there any use keeping it for hash making? I almost hope it is so it makes room for the others when it’s gone.
6) Any other general advice after looking at the plants would be good as I am a first timer

Details:
Growing indoors under two 250W CFL lights (left is blue spectrum, right is red spectrum)

Was watering every three days but plants got really dry and droopy towards the end but perked up when watered. Eventually got so bad I had to soak them in water. So I’m now watering them every two days. Always checking the soil is dry 1.5 inches below the surface first.

Growing in 80% miracle grow potting compost and 20% builders sand. Only 6” pots.

Two months from seed. Gave a hit of miracle grow fertilizer after 4 weeks and six weeks. Recently gave the flowering ones tomorite fertilizer at 7 weeks and again 25% strength 3 days ago.

Light was 24hrs for 5 weeks, 16hrs for 2 weeks and 12hrs for 1 week.

PH check of the problem plant was 6 so slightly acidic

As nobody bothered to help me I'll answer my own questions in case it helps someone else.

1) The pots wrer too small 6" is too small so repotted to 8" and found it much better.
2) Still no idea but it's now less yellow. repotted and given lots of foliage water sometimes with a few neuts.
3) Yep they grew larger, the biggest is outside the lights as it go too big.
4) Still no idea but more likely ounces than grams.
5) Never pulled it which was good as it's female. It's just too high for the grow space. Watching with interest as it's so tall and probably a duff sativa seed but it is now flowering if behind all the others.
6) general advice is don't panic and don't let veg for too long (as I did)


Same setup as before but 12/12 lighting and took seedlings to the bathroom window to rpevent early flowering. Chilli peppers done great and now in sisters greenhouse.

Now at harvesting stage and have a few more questions. Hoping someone will answer this time.

1) Does drying for 4 weeks by hanging upside down make such a big difference against just putting on a radiator orsimilar and drying over a few days?

2) So does curing realyl make a big difference (note I use a bong rather than roll so already very smooth)

3) The strength..... I took a small bud off my quickest to flower plant a few days ago, I dried it over a few days (still green) and smoked a bit of it 30 minutes ago. I expected it to be poor yet it's scary strong. I'm shocked is this normal? Is home grown normally so much stronger. (note: It's white widow and grown sort of slowly)
 
Replying to my own post but hopefully this will help someone.

1) Drying makes a big difference, not stonger but much much smoother to smoke. You even notice this using a bong. A radiator or similar does a pretty good job but natural is better if you have the time.

2) Not tried but doubt it'll make much difference compared to nicely dried weed.

3) Definitely stronger. Especially if using the same amount but after it's dried as the drying means weight for weight it's stronger.
