Here are the details:
Strain: Afghan Kush
Soil: FFOF mixed with bat guano
Light: 250w MH - 18/6 - 16" high
Container: 7gal smart pot
Watering schedule: every 4-5 days with filtered tap water.
Temperature: It's been anywhere from 76 to as high as 84 during the day, and as low as 65 at night.
pH: my tap water comes out at 6.9 and the runoff is at 6.5
Nutes: none as of yet.
Plant training: Started some LST'ing 7 days ago
The plant is 23 days old. This problem started about 10 days ago. I first noticed the very tips of the leaves curling down. I thought I might be over watering (was watering every 3 days before the issue), so I backed off on watering, and have been watering every 4-5 days since. This didn't help any. As a matter of fact it got worse. Now the edges on the side of the leaves are curling under and some leaves look a bit shriveled. I have not added any nutrients yet. I think the bat guano is still providing some nitrogen. I did add some CalMag + my last watering, which was yesterday. Noticed more leaves curling under today. Is it possible my tap water has too much calcium? Can LST'ing cause the plant enough stress to show leaf deformities?
Here are some pics. You can see some minor discoloration on the edges. Overall the plant looks healthy though.
