Is this heat stress? Young White Widow
Wontgiveupstarted grow question 5y ago
Hey fellow gardeners,
Is this young White Widow showing signs of heat stress?
With lights on, my tent is a constant 26-28 C (79 - 83 F) and RH is 64%-74%.
And I do trust my sensors.
Mars Hydro TSW2000 turned down to ~40% intensity. Light was ~ 10” from leaves. Growing in coco.

I wouldn't worry about it, Cannabis plants can grow strange leaves at times, but I would try 24 inches at 75% as a first option to see if that helps, if you are really worried about the leaves.

MH recommends 24” for veg for that light but they also give measurements for PAR readings at different heights, and I mentioned I am at 40% intensity (because of high temps when running the light at 100%) which is why I was lowering the light.
When I had it at 35-40%, at 24” my WW was stretching....

10 inches is too close for that light, better off at 24 inches for that stage of growth. Happy growing.

Looks like heat stress or a nutrient toxicity, could be nitrogen.

Overwatering?Can anyone confirm that this curling up is due to overwatering? I don't see any yellow leaves that would indicate overheating. But I read it could also be a nitrogen defeciency?
One pic is upside down, I wasn't stoned taking the pic, honest 👀

Hi all, I have had very slightly yellow tips on this plant for a while. She is mid week week 10.
Two days ago the leaves started to curl and the yellow has spread slightly. Last night I flushed her with PH water and have dimmed the light slightly, anything else I can do 🤙thanks

Problema con mi Runtz MuffinBuenos días,
Tengo un problema con mis hojas, (puse fotos para que podáis ver).
He visto que podía ser un deficiente de fósforo. Pero también puede ser un problema de calcio y de magnesio.
Alguno podría ayudarme con eso ? Que tengo que hacer ? Añadirle un PK 13-14 ?

Add on lightingHey Growdiaries. I’m about to start my 2nd grow but I’m not happy with my Viparspectra 300 for flower. I want a cheap add on for the flower stage? CFLs look like a cheap, low energy use, add on as I’m only growing two plants in a small w3xd2xh3 ft tent. Any advice plz & 🙏🏼Setup. Lighting
