Green Crack at 8 weeks

She's doing pretty well, I think. I can't tell if there's a nute thing going on, or too much light. Water is about 1/2 gal every couple of days. bloom nutes at 1/2, and CalMag at 1/2. Temp is 70, rh at 50. I have the light about 12 inches away at 10%. DLI is in reasonable range now, but it was high.

Maybe a tad too much light, download the ppfd or photone app and check it out. Has it been drooping for more than a day now?

 

[SylviaLynn]

It's better than it was. I use the ppfd app frequently. DLI is around 35 to 40 currently. Light cycle is 24/0 until I figure out how to keep temp (low), balanced with very high humidity. It did get way too much light when I forgot to change the setting on ppfd to 24 hours.

Thats about right for a flower on an auto, so its possibly the humidity. If the temp is low and the humidity is high thats a recipe for mold and bud rot though. If your humidity is high, like above 65% you're gonna want temps in the 80s if Im not mistaken

Heres a vpd chart. During flower you want it at .9 to 1.0 and I was a little off, depending on your humidity. Im guessing since you said high its above 65% according to the chart temps should be between 75-80

It really doesnt look bad though. Let your pots dry out completely and see where your humidity sits. What size pots are you using or are you straight hydro?

Yep, if I don't run the exhaust fan humidity gets up to around 70% or more. RH in my house runs 60%. That's a good chart. Keeping a 2x2x4 tent stable has been interesting. I think I mostly have the hang of it.

I run my exhaust 24/7. Usually dont go above 60% power though in my 3x3. Ive notice when plants start getting big and your tent fills up you really wanna be cycling that air. For me that moves 3x my tents volume per min. Turned it off for a few hours on accident over night and I actually had dew on my plants

 

[SylviaLynn]

Your plants look good.

Thanks my last grow was a disaster. So im glad this one is under control.

Check in to a.c. infinity. They have systems that will control temp and humidity by speeding up or slowing down the extraction fan. If you have a fan or 2 in the tent circulating air you don't need 3x per minute air exchange. But to each his own...
