A newbie--need feedback on this first grow!

[Psyche]

Guys--Things are getting worse. As a reminder: First grow ever: Very concerned about how yellow and droopy some of these leaves are this past week. Some details:

• AUTO seeds (Northern Lights, Blue Dream and Gelato from Seedsman planted in final pots on January 5; Sprouted–Jan 8
• Mars Hydro TS 1000 in 2.3 x 2.3 x 5.3 ft tent
• Three fabric pots–2 gallon each. Sitting on plant stands to allow drainage.
• Soil: Plagron RoyalMix with a layer of Platinium Lite Mix on top.
• Light: Currently at 75% intensity, 24" above pots. ppdf about 600 (using Korona phone app to measure). 24/0 light cycle
• Tap Water: ph to 6.0. No nutes. I water slowly 3/4 to 1 cup every two days. I am not testing soil ph.
• Temp and rh: This past week 77F to 80F and 45% to 50% rh. I have been able to get the rh to 80 if I closed the vents and the exhaust fan.
• Currently have both exhaust fan on top and small circulation fan on bottom on low.

They are yellow and droopy! How do I fix this? I appreciate your advice for THIS grow. AND THE LEAVES LOOK A LOT WORSE IN PERSON THAN THESE PHOTOS. Very yellow! Someone suggested the soil is too hot but I also read I shouldn't flush live soil (except before harvest).

Thanks!

See photos. (Compared to previous photos--definitely better but oh so small!)

I see trichomes. What do you see? What should I look for next? Any suggestions? Thanks, all!
