My lambs breath leaves are yellowing

[beyondskylines]

I’ve been noticing my plants leaves have started yellowing what do you think could be the cause? I recently got a bigger tent because my Mars ts600 was getting my small ass tent up to 91. I thought it was heat stress but the leaves have continued yellowing. I got this lady sitting in some nectar for the gods #4

Looks overwatered and underfed. Need more details than " #4".
