I have been growing this crop a little over 4.5 weeks and transplanted them 1.5 weeks ago and in the last few days this yellowing started happening I have not been able to find any similar pics as mine because the veins are still dark green, it's mainly on the top and works out from the center of the leaves. Please Help it seems to be going down fast.
What are your growing conditions like? There's a troubleshooting sticky at the top of this forum section.
Im using a high end soil mix from the garden center I forgot the name with perlite, worm castings and moisture control beads, Im growing in an enclosure I made that measures 8' long 4.5' wide and 6' tall under 4ft cool white flourecents with a small oscilating fan walls are covered top to bottom on the inside with dull side of aluminum and the outside black plastic there are no mites or flies visible either I have used some veg. fertilizer just starting working in at 1/3 strength
Okay cool.
First off lose the aluminum. REplace it with either mylar or white material- white plastic sheeting is easy to work with.
Those marks on the leaves- I've seen those on plants that at one point grew up into the flourescent fixtures while the leaves were developing. If yours are the same, it's strictly physical cosmetic damage and isn't a sign of any other continuing problem. See how they are just at the leaf BASE, and towards teh leaf tip is healthy?
The under leaves of all are fine but on the one plant that is the worst looking the tips are wilted and dark green. there was an accidental folliar feed shortly before this occurred but i shut the lights out immediately after, it was a diluted worm casting spray, very weak but it wasnt supposed to be foliar fed, not at that young. I was wondering if that might be the problem but if that were the case it should not spread. Do you think I should raise the lights up? they are currently about 3-3.5" above the tops of the plants. Thanks for all you help stinky
Tommorow I will repost with better pictures
Here is the better pics from a real camera any thoughts with the better pics?
These never got near the lights though, but no worries new growth is looking great
