Very unhealthy 3 week old plants. New grower, trouble diagnosing the problem

thebiologiststarted grow question 4 years ago

Please help diagnose problems in the "one week later" pictures. EC 0.7,pH 5.6 - 6.0. Humidity 47-55%. 1-2cm distance from basket to water, high air flow... Not sure what is going so wrong. Over watering? Nutrient shortage? Brown spots on leaves. New growth curling, dark and slow

Yellow leaves and spots Noticed some leaves growing yellow at the bottom of the plant, a few days ago, added biobizz bloom as I hadn't used any fertiliser yet. Today I noticed the spots on 1 of the leaves, veins in the middle have what looks like rust. Any ideas?
