Same here. I thought it was, well I didn't have a clue!
My entire veg room is LED and I've been constantly battling Mag def issues and low seedling survival rates.
I'm running Jacks Hydro, btw. I'm going to make some adjustments to the profile today and see how that plays out.
I will likely incorporate some flouros for heat and IR soon. Also adding a 315w CDM for the final stage table prior to flower.
I use led bulbs in my veg chamber and never had issues like yours.
Plants grow normally, stay green and show zero stress.
Only trouble I had was in early/mid flowering and once in late veg but was all about too few nutrients.
Keep in mind that most seeds you get anywhere are from plants which were selected under hps lights so the spectrum differences can put them under some stress, some more some less.
Cheers
Many thanks fellas for sharing your experiences.
These seedlings are too special to me to risk continuing under this light - perhaps I'll try it with some seeds I made - so I plan to put them under the CFL and see if they bounce back.
I have wondered a lot about that, Koondense. The lighting used in the selection and making process and to what extent it factors in...
Also, what of the color temp difference... possibly it plays a role? As mentioned, I am always under 6500K at this point and these babies are under even less wattage. Eh, maybe LED just isn't for me. Was already considering going back to HID this season to see if these issues are remedied - just may yet.
Thanks again.
