Bruce Banner is killing me. This frick'n plant. Leaves getting a lot of rust spots and more yellowing. I think it's nute burn at this point. I gave her two litres of fresh water no nutes and am gonna let her dry out really good and then give her plain water again. It worked last time, hopefully again. And if this works she's not getting any more nutes unless I see signs she needs it. Am I way wrong? The others all all perfectly fine. Critical Mass is perfect, not a fleck of yellow on it. Just bushy arse plant green as green can be. Very interested to see how Baby Bruce acts when she's bigger. I think I might just give her CalMag until she shows signs of deficiencies.
When are you going to switch to 12/12 to get your one girl to flower? She's at 37 days plus, right?
Also on the same girl, research pics of her and see if that's the natural form of those downward hanging leaves.
It screams overwatering, but there are strains where that's just the way they look.

I think she's sleeping when her leaves are like that. Every night around 11pm she looks like that, then next day all perky until about 11.
ok, RE: 12/12 lighting, but won't my auto's have too little light and lower yield? I'd have to then keep it at 12/12. Poor Baby Bruce!!
I was thinking of setting up a SCROG on the left side of the tent and put Critical Mass there. Then I'd be able to really spread out her branches and get her probably 6 inches lower than she is now and keep her low vegging until my auto's were done. Not sure what else to do. Open to suggestions for sure.

Ok....you know what she looks like at all times.
Right now, she's your best bet at getting a good harvest. Sure your others may have slightly less yield, but you'll have waaaaaaaay more bud that if you didn't flip.
Just make sure you have no light leaks and keep that in your head until harvest. Then flip to 12/12. In 3 or 4 days you will see flowering.
Just trying to help.
I don't really know what to tell ya on Bruce. If you have a moisture meter, probe down thru the layers slowly to get an idea of your moisture levels from the top to bottom. You may need to let her dry out somewhat
The name of the game with yield and reduced light cycle is, "Daily Light Integral." For example, if you have 500ppfd at the canopy for 24/0 light cycle, your DLI is 43.2.
If you have 1000ppfd at the canopy for 12/12 light cycle, your DLI is 43.2.
So it's no so much the hours of the day, it's the intensity of light received during those daylight hours. This is why autos grow well under less intensity, but longer day cycles. Since photos need 12 hours of dark each day cycle, you're limited to a 12 hour window to "apply light fertilizer" to their leaves, hence the increase in intensity seen in most photoperiod flowering rooms.

Yeah, I should have included that.
I just assume someone is already growing at the max intensity with the coverage available. That's what I try to do. In that case, switching to 12.12 would slightly decrease the total harvest. I've read there's an improvement of bud quality. I'll take quality over quantity any day.
Great info, but, do you have a link to calculate PPFD? Or would @Marshydro have this info for their lights? If so @Marshydro I'd greatly appreciate it.
Secondly, and most important, once I know these values, how do I know how much my plants need to be healthy? Again is there a link to a site with more info about min PPFD plants need in 24 hours?
Interesting stuff, way more complicated than I thought when I got into this hobby. One thing though, is I really want my Bruce Banner plants to be as good as they can be. Critical Mass, which seems to be photo is heavy indica although it is a hybrid. I do prefer Sativa, so I'm aiming for BB success here. But if I can get a great results for both, I'm happy to do that.

I responded to you on my thread about AN with analysis of your plants if it interests you. Another thing i have noticed is you have too much light in there for their size. Check your temp too.
You can by a quantum sensor to get measurements yourself, but they're expensive. Look for a PAR map on your manufacturers website, they usually list at least three; one at 24", 18", and then usually 12".
There are also tons of videos on YouTube where growers review lights and do their own measurements with their own sensors. LEDGardener is the one I use. I found his video for the light I have, and I use his measurements as a baseline for my grow.
Unfortunately it appears Mars only publishes one map for the TS600, measured at 18" hanging height.
Keep in mind that light intensity follows the inverse square law, so halving the distance does not merely double the intensity.

Check this out also. Keep in mind some of his values are for very large photoperiods grown in IDEAL conditions... YMMV.
