Day 69 yellowing leaves

Hi, first time grower here. I’m growing in pro mix #5, 10% worm castings in fabric pots. (2) Sf 1000 grow lights. FF nutes. I’m currently on day 69 with my Bruce Banner Auto. I had A friend look after my plants while on vacation. When I returned home my plants look like this. I dont Know If the leaves are yellowing and dying because they are near harvest, or lack of something. They pics are pretty shitty I know, but I’m just looking for some experienced advice and thoughts. Thanks in advance.

Those are probably a good 5 weeks before they are ready for harvest. The plant looks like that from a deficiency or multiple ones.
