I searched the forums but I couldn’t find anything that would fit my situation.
I germinated my OG Kush Autos in rock wool. they started popping 5 days ago. I had them in a propagator with/ Dome and heating pad. I immediately lower a 2’ - 2 bulb T5 light close to the dome without touching it. The early sprouts stretched to the top of the dome by day 3. I had to remove the dome, still keeping the light as close as possible. I turned a fan on low to try and strengthen the stems.
The early ones still kept stretching. I assumed that they must be reaching for the light. Yesterday I removed the T5 and lowered a 600-watt full spectrum led to slow the stretch. I had to give the Rockwool a spray or two because they were drying faster than normal. ( I assume)
Today 2 seedlings feel over. I propped them up with toothpicks. I noticed that the main vein of the leaves and the second pair of true leaves seemed to be a little yellow. I raised the light about 6", but I don’t know what the hell I’m doing!!!
I have a 1020 tray with 7" dome coming. What else can I do or look for?
Your time and help are much appreciated!
