How does my first grow look?! 4 strains!

First time being able to do a full grow and it feels gooooooddd. I have 4 feminized girls under 400w of vero29 gen7 cobs from timber. They're sitting happily in 5 gallon smart pots in some ffof and being supplemented with the ff trio and recharge. Each were fimmed at the 5th node except the OG#18 which I accidentally topped. All of this sitting in a 4x4 tent with one fan and a pretty decent carbon filter setup imo. There's a little cheap blurple light I recently threw in there for shits n giggles for a little extra coverage. Temps stay between 77-81 during day and 71-74 at night with humidity hovering between 44-62%. Did 4 weeks of veg after letting the seedlings grow out and they are now on day 28 of flower. Had a full week of absolutely poor lighting due to power outages from Irma and I think they recovered nicely now. Strains are:
OG#18
Super lemon haze
Chocolope
Northern lights#5xHaze

So, how do they look? Can you spot any deficiencies or toxicities? I think the OG#18 is showing some light yellowing at the top but not sure what it is.

OG#18 picture turned out more yellow than it actually is but you get the idea

SLH! My all time favorite strain!

Chocolope ...this girl is blowing all the others out of the water. It's currently the tallest by at least 7 inches so I had to stack some of the other girls on boxes. Extremely vigerous growth with an excellent build!

Northern lights#5xHaze! Extremely excited for this strain as it's the closest direct haze cross I have. Hopefully these excellent genetics really put out some top shelf!

Your og 18 looks like it will be very colorful. Congrats. Your risking mold, especially later in flower with your humidity in 60's.

In our opinion they look great!

Looks like you have room to space the pots out a bit. Not sure if you're keeping them in the middle because the COB's are most effective there. We have no experience with those types of lights.

Thanks! Luckily the humidity is in the low 50s more than the 60s so hopefully it's ok. I was looking to purchase another fan to hang in the corner of the room, do you think that'll help with the mold?

Right on thanks for the kind words. I'm trying to keep them closer together to keep the highest light intensity available to all buds. Things are getting a little cramped though so I bought that blurple light to help with some of the sides more once I rearrange them. I'll be spacing them out slightly tmrw I think!

Make sure you have good air movement at canopy level and under the canopy too. Good luck.

I would be careful growing 4 strains in one tent at a time. Different growth characteristics can really mess with things because of height differences. So far though it is looking good and looks like you might have gotten lucky with those 4 staying close together in size.

Give them girls a little space. All the buds on the branches where all 4 plants meet together are being shaded. Despite being directly under the lights, there are nearly entire branches being covere. I made this error in the same situation you are. 4 strains in a 4x4. Give them a little space and those lower buds can get some extra light! Looking really good so far man!! Nice job!

Also if you need a little extra space. I take those rolls of green ties and tie a couple strings from one corner along the wall to the next corner. That way when the walls try and flex in from the fan, the ties will keep them in place and give you as close to the 4x4 actual size

Oh it's proved to be difficult but decineteky manageable. Most of the main colas are within about 5 inches of each other, but that's only because I've raised the SLH and the NL5xhaze with some sturdy boxes. The chocolope is currently sitting at 33 inches tall while the SLH is only 22! Both are doing very well I think but very different builds for both. It seems the SLH leaves are sativa leaning but has a very short bushy indica build to it.

Yeah I'm trying to keep them all in a 3.5x3.5 area as that's what my lights coverage is rated at. I adjusted them all yesterday and they look better now! I'm inside the tent every day adjusting things and adjusting leaves so they don't cover bud sites and doing light trimmings here and there. I really wanna defoliate a bit right now but hear a lot of mixed reviews. You think I'd be safe giving them a decent trim right now?

I've always LIGHTLY defoliated up to about week 3 of flower. Basically once the stretch is over. I haven't seen any adverse effects from it. But be careful because after week 3 its done growing new leaves. So just remember not to go to heavy on it.

Oh gotcha, I assumed they produced new leaves throughout their lives. I'm going to try and pluck about 10 leaves per plant. I'm gonna try to avoid taking any fan leaves off but they're definitely the ones that need to go the most while shading is my problem. Thanks for the helpful info!

Yeah they stop growing at about week 3 or 4 of flower and focus on just bud production . Just take the biggest and oldest fan leaves from the top and a small amount through the middle sections. Just enough to let some extra light in
