Lighting Autocob and Apollo 11 Grow

[BmC76]

Alrighty...now running with the final cob config: 2 4000k 97cri & 2 2700k 90cri

It really is amazing the difference between the two A11 grows. My first A11 grow was under 250w true of panels. It was a total of 7 plants (from seed), vegged for 5wks, in 1gal fabric pots and they ended up in getting away from me due to stretch. My scrog became useless so I pretty much had to supercrop throughout the entire grow.
This current grow is very different. Running w/ 4 plants (clones) in 2gal hempies, vegged for 3 wks, and under 220w of cobs.
Can you notice a difference, lol? (ps...1st grow netted 3oz dry)
1st grow at day 18 of 12/12:

Current grow at day 21 of 12/12:

So I had to raise the lights and remove the reflectors. At 15" w/ reflectors they were starting to cause light burn and started to bleach the top of the buds.
They're now sitting 20" above the canopy.

Looking great sir. You have 4 in there correct? What's the amount of calmag your adding? If I remember correctly 15" with reflectors is somewhere around 600 umoles hitting the canopy. Just saw a guy earlier saying 1000 was needed but he got his info from the photo period forum. Another example here of the light and strength needed with autos.

 

[BmC76]

Thank you, sir! Yep, 4 of them (2 4000k 97cri & 2 2700k 90cri)
I'm using 5ml/g of calmag plus (2-0-0).
The strain (60Sat/40Indica) I'm running is a photo.
1000 umoles? Wow! I know my ladies were screaming at me when they were getting 90k lux, lol. With raising the lights and removing the reflectors, they're now getting around 75k in the center and 62k lux on the edges.
This picture was taken right at lights out this morning:

You can see the damaged leaves on the plants in the upper portion. At first I thought it was a lack of N, but it's only affecting the middle leaves and not the bottom leaves under the screen. At least I'm assuming it's light burn. I'll get a shot of the buds tonight when the lights come on to show the light bleaching on the buds.

So the ladies are still going strong. I'm not sure now if I was getting light burn or simply a mag issue. I trimmed the damaged leaves and fed using water with 1tsp/gal epson salts. My ph going in is 5.8. I'm going to up it to 6.0 and see if it helps matters as well.
One thing I'm noticing is that the trichs seem more abundant on buds that are further away from the light...anyone else notice the same?
Anyways, here they are at day 25 of flower:

Today is the start of wk 5 of flower.
Still having an issue with the leaves turning yellow. I think I've narrowed it down to a ph issue, so we'll see.

Did you start the cuts off with a 12/12 light schedule?

Did you start the cuts off with a 12/12 light schedule?

No, sir...They were rooted under 18/6 and once rooted, vegged for 3wks under 18/6. I wish I would've given them another 2wks or so of veg, but I didn't want them to stretch more than they had, plus I'm running on a time constraint. If I can pull 2.5 zips dry from this run, I'll be happy though.

Looks like you far exceeded 2.5 from the last picture. That space is amazing looking.

Thanks! They're doing far better than I expected!
One thing I've noticed is that the buds are "blowing out" on the sides. Probably not the right term, but basically the buds are fattening up as well as pushing more calyxes to the side of the bud, if that makes sense. When I ran them before, the buds were more or less uniform, having a pine cone shape to them...these have the same shape with the addition of being a lot fatter to one side. I don't know, it's hard to explain...definitely not complaining as more bud is more bud
I've also noticed there hasn't been a lull in the bud developement. Last run, the buds pretty much didnt have any real growth during wk 5 and 6 and then threw weight on the last 10 or so days. These seem to he packing the weight on everyday.
One a side note, I think I got the ph issue under control...after getting a new meter and adjusting to 6.0, I haven't had any new leaf damage.
