Was going good then yesterday i noticed a little bit of a yellow on its leaf. woke up and it has got worst. temps are 74-82. about 20 inches from 300 watt led. jiffy seed starter and distilled water. The rest of the grow. Its my first grow all random seeds.
The only yellowing I can see is on the cotyls which is no big deal... I can't tell anything on the purple pictures though. They yellow just as all leaves do there only useful the first week or two anyway.
