I had leaves show yellow edges and between veins, plants are darker than last week. I've ph'd the ro water with to 6.7ish with 10ml seaweed and watered every three days or so when soil is dry on 10cm top. Plants are all different sizes they seam quite short and the apical meristem is densely compacted to the new growth. I brewed tea and once it time to water I'll dose them.. No feeding till date
Is yellowing of leaves and dark leaves toxicity? no curling . moved the lights further away. I'm growing organic. The plants look stunted short dense. I've only got a cheap pH meter calibrated. 🤞 use RO water pH- citric acid. Overall they are short dense growth wise
Early signs of mag, by the banding on the leaf margins. N def as well from that little leaf guy at the bottom. It is looking like you need to feed em more. I'm not seeing any tox and your tips aren't even N burnt.
The nutes you are using are a 2-5-4, which would explain the need for more Nitrogen.
Also, organic nutes take a week or so to break down, so you've got to think a week ahead. Also, 6.7ph is a lil high for organics, shoot between 6.2ph-6.5ph for your soil. The more food and microbes in the soil, the easier it will be to maintain the PH of the soil.
I'd use a fert with some water-soluble mag in it for instant relief, and add some more N to your regiment.
