I'm going away for 30 days about a week into this grow. I'm going to automate weeks 1 through 5 by using the Blumat watering system along with the automated fan from AC Infinity. Hopefully, these will keep things going while I'm gone. I've never used the Blumat products before and I'm excited to see their potential. If I succeed, I'll return to happy 5-week old plants. If not, I'll have to start a new grow...which is what I was going to do anyway. I have nothing to lose but a couple of seeds. Let's get this automated grow started.
Day 1 - I placed the seeds directly in a fist-sized clump of Coast of Maine Seed Starter soil that was then placed in a 3-gallon pot full of Coast of Maine Stonington Blend. This will ensure the seedling doesn't get exposed to the nutrient-rich soil too soon. I set the light 2 feet above the top of the pots so they have room to grow into the 18" to 12" range. I also set the light strength to 60% during germination. The temperature in the tent remained 75 degrees and humidity was 70%. I also covered the soil over the germinating seeds with mason jars to act as humidity domes.
Day 4 - Both pots sprouted this morning. I immediately removed the mason jar humidity domes. I also increased the light to 70% strength and installed the Blumat watering system to help me keep things growing while I'm gone.
My two Grandaddy Purple Autos are light green/yellow in color. Is a lack of nitrogen the cause or is it something else? What do you recommend to fix the issue?
Light is too close too soon. Apparently the others did not take the time to look. You got light stress. Should be at 14 to 16 inches in heavy flowering.
