Thank


Thanks for that Pilted, I'm a big proponent of less is more. I'll post results.
I would probably drop it to 500 top heads, 300 edges, for veg the recommended level is like 300-400, but your not seeing patchiness from the light so I would assume your plant can handle a little.more light. 600-400 might still be a little high.
 
Currently light cycle is 18/6. 5pm on, 11am off. I took those particular pics 1 hour after lights on at 6pm.
So after hours of dark, the growth that happened during dark is going to tend to be lighter, it hasn't had the light energy yet. If those areas darken up over time and the lighter nrw growth seems to happen consistently, it could be perfectly normal.

That doesn't mean your light isn't too close/too powerful. I had to deal with that, and it isn't easy to catch super early. You don't want to discover it after tips, tops, new growth actually gets burned. Early on it has a certain look. It's like it's easy to see a sunburn. It's not as easy to tell if someone is in the early stages of getting a sunburn.

Yep. I don't have a meter for these numbers so Pilted knows about this. You can always increase light, you can't un-burn...

Yes, to your point, when I left for work this morning and the lights had been on all night, the new growth was definitely looking darker. I think the real benefit of posting tho was the heads up on the light intensity. I will definitely back off that significantly.
 
@Harpua88 I did my defoliation yesterday, only removed 8 leaves. Thanks for suggestions in my forum post it was very much appreciated. She getting decent light into the canopy and only took off very little.

Yeah, sometimes it's not about "one thing". There could be more than one thing going on, or one thing can lead to another. You're doing right...

They look great, right on. You can reassess things over time. Maybe some of the very bottom/oldest leaves can go.........how about tying down to expose branches? Or fan leaf tucking. They pop back up over a couple of days but both of these things allow light to hit branches without cutting any leaves.

Yeah I think I could have taken some more off the bottom as well, but I wanna see how it plays out, it might use some energy where it shouldn't and effect yield a little, but after a few more weeks if i see lower branches not devolving well, I will make adjustments. For now I am happy with it and will give me a good contrast against one of my earlier grows where I defoliated very heavy. The lower leaves I am more or less leaving as they do not effect light penetration or air flow, and will give the plant some stored resources to draw from if I drop the ball on feeding.
 
I prefer not to tie down, and try to softly encourage plant to grow where I want, I spread it out a few days before defoliation by taping a leaf from a few branches to the side of the tent, which opened everything up nicely. It's getting decent light into the canopy, lower leaves and branch removal could be a mistake on my part but time will tell.

It depends on how productive that bottom growth is......what it will take vs. what it will give back. But pruning, trimming.....I hate the term "defol"... ;). It's more of a philosophy. Once you take a stand for being very stingy with cutting it carries forward with you.

I agree with everything you said...except for not tying down! How dare you!!! Ha!

On my just-finished photo grow in soil, I left many of my lowest fan leaves until late into flower. I like to keep some on that part of the plant as an early warning system. Some plant problems show at the top, some at the bottom. Without those lower leaves I have less time to react when something goes awry that shows itself on the lowest remaining leaves.
 
Yes. You see how some of your heads are not looking at the light and how some are kinda just laying there almost like they are taking a nap, when in proper light they will be stretching towards the light in a praying manor, when too much light those heads will look more like what I see in your pictures, not the other person that posted after you with the other pictures. I really think you have a couple issues and too much light at this stage is one of them, the lower leaves that's not light avoidance so something else is going on there also, but I think pulling the light back a few days will solve one issue. Again too much light will slow growth dramatically so if you haven't noticed slower growth since you increased light then maybe I am wrong and it's something else. But if that was my plants the first thing I would do is pull light back.
@Pilted here is a pic of a white fire og. I flipped these last saturday, so 4 days into flower. Does this look more like a good light response? I ask because I intended on lowering the ppfd's on these as well as the troubled ones, but they look perky and they are at 800 ppfd so I would appreciate your opinion.

Those look great, once stretch comes to an end, I would increase the light range slowly going up to 1000 and watching the plant for any signs of stress. That's what I did with mine. When the stretch phase was over, I raised intensity, at about 940-980 I started showing some of the top leaves starting to taco. So pulled it back to the 900 range. My lower heads are in the high 700s low 800s. During stretch I was at 700 top heads, high 5s to low 6s lower heads. Only having to move the light once or twice a day now, during stretch was moving it 3-4 times a day.

Even tho they look good, I did dial it back a bit and will increase after the stretch. PPFD 700ish/DLI 28, Thanks again
