Auto GG4 first grow

Planted the seeds in Kellogg Garden Organics Potting mix 10/2/20. Cotyledons were visible 10/7/20. (10/7/20 shall be known as Day 1 of this grow). Plants were under small led grow bulb for 10/7-8/20. Switched to Mars Hydro Ts1000 on 10/9/20. Ts1000 is located 24" above the vegetation. 10/10/20 (Day 4)- Transplanted into 5 gallon fabric pots. Filled with perlite at bottom for extra drainage, and Dr. Earth homegrown our and natural potting soil. Top 4" of soil in each container mixed with 1/4 cup Dr. Earth root zone starter. Switched TS1000 to 100% power and hung 26" from vegetation. Watered around bases of plants each received 300ml. 10/11/20 (Day 5)- Plants are both 2.5" tall, noticing slight yellowing on #2 leaves. Perhaps too much light, will check back tomorrow. Soil still damp, but drying, watered 200-400ml per plant. 10/12/20 (Day 6)- Second set of leaves emerging on both plants. #2 slight red tint on new leaves in addition to yellowing. #1 leaves are slightly curled downward, perhaps over watered. 10/13/20 (Day 7)- Plants installed into new 70x70x160cm Marshydro grow tent. New light, Galaxy hydro 300w hung 30" from vegetation. #1 leaves curled more downward. Watered 200ml each plant. More research has been conducted, proper watering may be 200-300ml every 2-3 days, will try this and see is problems persist.
