Yellow leaves purple stems and aphids

fatbuenostarted grow question 5y ago

My sweet ZZ had aphids. Washed them off plain water, put gaasvlieg larva on them to eat the aphids. They came back and heavily infested some leaves. I cut off those leaves. This is one week later. She was the best smelling one, now she smells kinda bad. PH is 6.5 1200ppm week 8

Yellow dot on first leave Can anybody identify what may be causing the yellow dot on my Simple Wedding Cake and autoberry? Could it be a bit of light burn from a water droplet on the leaf or something that needs addressing? Thankyou in advance

Leaf Yellowing?What is the yellowing in the last pic? The soil is top 20% Atami Cocos, bottom 80% store bought organic super soil. Watering tap water (EC 0.284/142 ppm), pH'd down from 7.9 to 6.5 with citric acid... I think that's probably the problem? Any advice for the high pH tap water?

Lower leafs getting yellow tips and spots I just noticed that the lower leafs are dying, while other leafs are getting yellowish spots. Is this some kind of nutrient deficiency? The leaf with the yellow spots is near the air intake. They didn’t get any fertilizer except root juice since the soil is still somewhat fresh.
