Help for a beginner 🙏Please help me with these 3 plants. What's wrong with them? They're 27 days old, both in soil 6L pot and LED lights, they get Canna Bio Vega, Rhizo, and Biobizz Calmag. Water PH is around 6.9 and they are Enectaliana seeds. Thank's for your help in advance! 🙏🙏😘Leaves. Color - Pale

Pale green leaves with reddish tips?Stress at the top of the canopy. Is this heat stress, light burn, or a combo? Something else?
Temp in the tent hit 92.5 F at one point, but it's been high 80's in the tent and the leaf surface temp's have been low 80's.
Light was 14 inches at one point but now 24 inches4y ago
