I grow in soil and I'll try to help. I hate trying to decipher stuff from pics, just because the difference between lighting/camera/ etc. can be deceiving.
Here's an opinion, but be careful - I'm fucking high - ask for clarification if needed
I try to keep stuff simple. I see "light green leaves" I think low nitrogen.
For me if I see anything that resembles low N, P, or K (big 3) - I think hungry.
I feed at 25% of the recommended dosage of my nutes
Not random. I do this because I heard a tale that most feeding schedules are based on a lot of plants under 1000w of light (easy math). I have +/- 250w in each of my flower rooms. 25%.
If I saw this I would bump it to 50% for the next feed, and regardless of what I did last time using a feed-water-feed-water schedule, I would feed next.
Don't short the calmag.
I'm a control freak and I use RO water, then I put in what I want. I had plant issues doing this, until I realized I was reducing the cal-mag to 25% along with the feed stuff. Bad move.
Silica supplements are good.
I hope this buck-shot blast of nuggets helps
