Heat stress or calmag?...or neither?
greenthumbartisananswered grow question 6y ago
Kind of looks like it could be both light stress and calcium issue.

Tacoing after switching from VEG to BLOOMAfter switching from VEG to BLOOM at the same PPFD, the leaves started tacoing - even at just 150 PPFD(like wtf, that’s seedling-light), while lower leaves get only ~60 PPFD! Is the red spectrum really that much more intense, or could something else be causing this light stress?

Has anyone else heard of using epsom salt with gallon of water for magnesium and sulfur issues? I'm told you can water them or spray them during lights out. I've had some issues before with magnesium due to soil pH recommended by maker didn't follow it I later corrected it pH

Leaf curling and mistingLeaves curling in one plant is worse than others.
Just noticed the leaves are curling worse on one plant, I think it's the one that had wierd genetics due to coming back from the dead early on
The soil was quite dry before watering today
How often should I be misting the plant

What do I do about this fungal infection?Follow up to my previous question. What do I do about this infection? It's fungal. I have crop defender 3, but the plant is starting to lean because of the weight. Help?! She is also killing another set of large leaves. And she's healing, I think, but it's taking too much time.

Organic soil 0.1-0.1-0.1 60% soil 40% perlite soil is pretty damn dry on topThe girls seem to be doing ok, little bit of curl up on some of the leaves, which indicates I over watered, humidity is usually 40-50%. I water 1 time per day with a mister, it's only been last few days that leafs curl up. Is it time for nutrients?. They are 10-11 days old.TIA

WHAT IS CAUSING MY LEAVES TO CURL? (Day 64 pictures)The leaves at the top of the plant seem to be curling up. My first guess is that there is too much light. I recently moved my light down to 12 inches above the canopy. The PPFD should still be under 1,000, but I don't know what else could be causing it. Please help. 🙏6y ago

Hey guys. Leaves not curling upwards as such but I'm getting some leaf tips that seem to be reaching upwards slightly. Does this mean I need to up her cal and mag intake? I read somewhere if the leaf tips are starting to "pray" towards the light it could be a cal/mag def?Week 8
