Today is day 14 on the Hindu Kush Autoflower grow. So they are officially 2 weeks old from sprouting above the ground.
On day 12 I changed my light setup on my customizable DIY LED Grow Light to 5 8 watt LED bulbs at 5000k color temperature. So currently I am running 40 watts total of LED lights.
A couple of days ago I realized one leaf on one of the plants had a rusty looking spot, which my guess was a minor calcium deficiency. The nutrients I am using on this grow which you can find HERE, I know do not contain any calcium. So my original plan of watering down my tap water with distilled/RO has now changed. My tap water is very hard so I’m sure it has a lot of calcium in it. So I decided to water my plants now with pure tap water, PH adjusted to 6 with vitamin C powder, and once every few watering’s I will give them pure distilled/RO water, to kind of flush them out.
