Bubble Gum on cheapest hydro

Hello everyone! Unfortunately, the second week began with a small problem: the leaves began to turn yellow from the bottom up. The first thing that occurred to me was the weak genetics of the seeds. But still it was necessary to exclude other possible causes. 1. The pH of the water has been adjusted to 6-6.5 2. Added fertilizer, as the symptoms were very similar to the lack of N (although this is unlikely, as the soil is from a good manufacturer) 3. Began to turn on the plant airflow for several hours a day. After 2-3 days the plants have grown a bit, but the unhealthy appearance of the leaves is still present. It cant be overdosing with fertilizers, because the new leaves still have a light green color. At this stage it is difficult to draw any conclusions, but I really hope that everything will be fine and I will not have to say goodbye to the plants.
