Not sure what’s going on here…

Leaves are bending upward on the edges, and the veins of the leaves are very visible.
Light is set at 150 PPDF.

Its a bit warmer then your plant wants it to be, the lifted edges are a sign of extra transpiration beyond what should be necessary. See how its more noticable on the growth closest the light?

Could also be humidity too low, can cause extra transpiration too. but since concentrated closer to the light, doubtful.

But yea, thats minor heat stress, the actual symptom. The cause will be one of those two mentioned things most likely. Could raise your light, increase airflow, whatever you need to get temps under check.


looks like your girlie is about to start asking for more N then you are currently giving her too. Id up the veg feed regiment just a bit on her. See how the older leaves are a paler green then the newer leaves? That will likely progress into N deficiency with a bit more time. Pretty much all mobile nutrient deficiencies will start with older fan leaves going paler, then yellowing off as the plant pulls nutrients from them to fill the gaps in what (not) its getting from the soil.


Whats you root medium and input/drainage ph?

I concur
Lights up
Humidity check
That's for starters

Thank you, I did give it a little bit of nutes today and raised the lights.
Humidity around 60% - I can raise that, if needed.

Thank you for the advice.
I went ahead and added some Roots Organics Nutes for veg phase. You were right on about that.
I raised the lights up some more. They on the lowest intensity, but very powerful in my 3 x 3 tent.

I wondered about humidity more than temp - the humidity is only 60%. I can increase it if these interventions don’t help.

60% is fine. Mines at 55% where my seedlings are. Temps about 78. If I looked real close one of them might have a lifted serrated edge or two, but they'll be fine.

The thing about the leaf edges lifting at the top of the plant but not the bottom, is that is your tell that it's temperature and not humidity.

Humidity is going to be pretty much the same at every part of the plant that size. The temperature won't be because you're using a grow light lol. There will be measurably more infrared energy at the top of a plant then the bottom.

Root Medium is happy frog soil from fox farms. Not sure on the drainage ph. I always put in water at 6.4.

You all are amazing. Thank you for the information. I will lower the temp and keep humidity same.
