I think the same way. Leaving reds and side lights alone, and dimming main. The likely outcome is re-greening of foliage (chlorophyll). Looking forward to the next update. They are at key stage in development. It was good to see the difference between last update photos and previous week. Looking forward to the next update. Fatter and smellier.

maybe it makes click and i find something else, till then i think its light intensity related and read stuff like this.

i hesitate to go really low with the PPFD.
think i stopped it, but am not in recovery mode.
normally green dots appear when they recover.
in the past i tried heavier doses of magnesium to fight the problem, it helps somehow but wasnt the reason.
recovery was always light level related so far for me.

thats AFTER i went down to 175W mainlight and 15W 660nm reds.forgot, 60W buddies of course, 30W from the top, 4000K 95 CRI.
i still give everyday the uva for 2h, all the time so far, no change there.

everywhere where is more shadow is more chlorophyll. (i have some more xtreme examples then this).

yes the "runt" no.3 is good, lol.
smells the best also.
i may self him.

order completly changed.
number 3 and 4 , the ones in the back are my favorites.
4 is doing the fattest buds, 3 do some more therefore.
both smell good, 3 a bit better maybe.
bud to leaf ratio is good on both.
one of them is maybe my keeper for a rerun.

no.2 stayed small, still nice buds.
no.1, hm, lets see, smells quite different then the others and have the worst bud to leaf ratio, somehow still a impressive plant, vegs like crazy btw.

should be D48.

buds are developing nice.

a quick look on the wattmeter show me 180w mainlight, 18w 660nm red (30+30W buddies also) and i think its still too much, while it should be near.
probably 200w should be the max for me, 210W when including 2 buddies strings to the mainlinght maybe.

that read is quite good btw.
the pictures arent bad.

tbh i had, the thought is not crazy at all (simply a sheet of a lee filter 1/4 frost).
mounting a frost filter with a inch distance would create kind of a soft box.

but the light should be quite soft allready due to the many light sources and their spread,
or in other words, hardly have any shadow.

diffusor includes losses, to hang it higher for diffusion is maybe the alternative incl. less losses (i havent measured, just a guess).

i would like to see some 285-395nm spectrum but i know im aiming high there
Not 100% sure, but I believe I saw him post somewhere else that he had some sort UVA supplement in the works. My assumptions are that it was some sort of buddies package, but again I could be way off.

edit: maybe @Grow Lights Australia might be able to give some more factual information on this though..

It helped my lettuce to have a sheet of greenhouse lexan between them and the light. It visibly shifted the color, would be curious what you would observer with your instrumentation.
