Good morning everyone,
Everything appears to be going well with my seedlings to the exception of a bit of leaf discoloration on a couple of the seedlings.
The plants are at eight days from germ.
After a bit of research I believe I’m looking at a bit of bleaching from the light being a little to close.
The light I’m using for the seedlings is a single Cree 3590
COB fixture driven at 54 watts.
I was slowly lowering the light in order to find the sweet spot.
For approx. 30 hours I had the light at 14 inches above the plants.
Whereas I was noticing a small amount of discoloration in the plant shown I was chalking it up to a variance in strain.
I now see where the discoloration has become more apparent.
I’ve raised the light up approx. four inches making the height around 18 inches from plants.
Temperature in the tent averages 75 F with humidity at approx. 70 percent. Higher humidity for new seedlings.
I have two six inch fans running.
I’m using distilled water with zero nutes added at this time.
I’ve added mycorrhizal fungi in the soil and around the base of the plant at time of transplant.
I transplanted due to seedling stretch being a bit long.
Any input would be greatly appreciated.
I’ve been studying a bit more and have found that a bit of yellow is normal on aging leaves.
I also failed to adjust the ph of my water that I used at the time of transplant. The ph of thre water I gave twice to the seedlings is sitting at approx. 7.00 Again I have given no nutrients.
