The HPS has been on for 2 days and there's definitely a noticeable difference. Those LEDs suck.
Yesterday I fertilized them, it was a bit experimental - I'll keep doing it for a while.
* 2 are getting watered with the brown liquid that collects at the bottom of my worm farm.
* 2 are getting dosed with some organic seaweed type of fertilizer. High nitrogen.
* 1 is not getting anything, just water.
* 1 is getting seaweed stuff plus some granule fertilizer (this one is over fertilized for sure)
I also put up a frame on 2 sides with foil covering it. I know it's not ideal but it was the most simple and quick thing I could think off.
The other good thing is that the light has made the place a bit warmer. Temps were about 15C (59F), now they are about 18.5C (65F). I can't get them much warmer at the moment, but I think the foliage should be pretty warm this close to the light.
Man, what have I done? These seedlings aren't do very well at all. The are going all yellow. New roots are growing daily at the bottom of the pot though.
This one I fertilized a little...
This one I didn't fertilize:
What have I done!?
I had to prop a couple of them up also
Also let the soil dry out a fair bit this time.
For my next grow, I'll be using seperate blue (veg) and red (flowering) LED bulbs in conjunction with my 600w MH/HPS light as supplemental canopy lighting.
You could try keeping the LED panels in there now...as supplemental spectrum lighting with your HPS.
Going okay. Leaves on most of the plants are still really yellow though. Anyone have any ideas?
The one that I over fertilized (seaweed fertilizer + granule stuff) is showing signs of it. Curled leaf edges, but it's also growing the quickest, thickest stem and the greenest leaves (although they're a little patchy in color).
they couldve been stunted but the one i had showed like at 15 days,it was cool,a two in plant burstin with hairs and branches,it grew up to a 19 in 1.5oz perfect smoke
