Growing, with natural light or T5 lights

[stormlady]

I have started, my seeds an then they went under T5ho lights an were doing great until I started taking them to the greenhouse to harden up so I could plant them outside. When I thought they were ready I planted them an all the leaves started to die off but the new growth that has started since they are outside are looking really good.

I had some other seeds that I started in the house but didnt put them under the T5's an they are outside an looking great. I tried an experiment an put 4 under the T5's an they werent too close 8 inches away from bulb. an these started to get sunburnt so took them outside to the greenhouse. I am using growtek nutes for them an also GO CaMag +.
I was wondering if anyone can tell me as why this is happening ? I have seen plants that others started under lights an then went outside, why are mine burnt?

I've never really heard of this before, I'm just as puzzled. I have a few questions for you:
1. Have you been treating all of your plants with the same amount of the same nutrient solution?
2. What's the heat output and lumen rating for the T5HO lights?
3. What's the temperature and humidity inside?
4. What's the temperature and humidity outside?
5. How are you germinating your seeds?
6. What medium are you moving your seedlings into, and have you added anything to the medium?
7. How many weeks old are the seedlings when you transplant them?

Hopefully you will know whats going on soon.

I have t5's 6500
An yes they have all been given the same amount of everything. The 4 experiments that I tried 3 of them the leaves started drying up the day after I had them under the lights so I took them out.
I planted them in pro mix an compost. All my other ones that are outside look great. This was the first time I have used T5's I germinate the seeds in paper towels keep them moist. I did add some lime to the soil. All my plants are in the same mixture I dont know what the humidity is I know it is higher in the greenhouse. The last 2 weeks they have been outside an looking perky the ones that were under the T5 when put outside they burnt. An I had them under the t5 after I transplanted them they are about 2 months old. At least they arent dead lol but looking sad I am hoping that things look up. I was really looking forward to getting some clones from them. Some are dutch seeds an some are bag seeds an the bag ones an dutch ones that were under the light an moved outside. the top leaves look bad but the new growth is really healthy. I feed them once a week an I am giving them less than what it calls for. since they seemed stunted they were inside then went to greenhouse an then moved outside still in pots an I just planted them outside about 2 weeks ago

That's weird. It's most likely just shock due to environmental shifts, however since the new growth is fine, I say don't worry about it, but I can't really help you with isolating the cause. Maybe it was the lime?

if you take a indoor plant and put it outside all at once you could be shocking it. my veg plants for my garden are started indoors then when its time to plant outside I let them get used to the new enviroment. letting them get a rest in the shade before they get the full spa treatment. just something to ponder
