RFarm21started grow question 4y ago
Hello growers.
What could have caused the deformation of these leaves? My LED is 300w, it's at 60% of its power and 60cm away from the plants.
The humidity has been between 60 and 70%, maximum temperature is 20°, minimum is 18.
I use Biobizz lightmix soil.

As soon as the 2 coteloydon leaves show, photosynthesis begins. Humidity over 60 will suffocate the plant, it will close the stomata on back of leaves to prevent "drowning". Photosynthesis grinds to a halt as does water uptake.
40-55rh
Don't focus to much on distance recommendation by manufacturer all they care about is legal liability, get the light close enough to achieve a leaf surface temperature of 86. This is optimal for photosynthesis. Try ambient -83 84 with leds distanced to top of canopy reaches 86.

I've been watering with a 72-hour interval and haven't given more than half a liter of water yet. I'll start giving nutrients at the beginning of week 3.
The pH of the water is 6.5.

GrowCNanswered grow question 4y ago
When and how much are you watering? It doesn't look bad but it could be slight over watering.
Especially because of your cooler temperatures. A plant will use a lot less water as the temperature drops. Unfortunately that also means the plant is taking in fewer nutrients and growing a little slower than it would if it were warmer.
Are you pH'ing your water?

Strange Twisting LeavesI have a plant that's just over 3 weeks old, and since the first week or so, I noticed it has some leaves that grow with a "kink" or "twist." They all seem to have a small discolored spot on the edge of the leaf that eventually becomes the corner of the kink/twist

Plant WiltingHey everyone. I think I messed up :(
My plant is dying. I might've had nutrient burn so I flushed it till I got 400 TDS.
Then I sprayed it with EcoRaider Spray (claiming to be harmelss and all) and now this:
its in the week 10. Do you think I should cut the buds and dry or?
