Hi everyone, this plant is cream mandarine on day 37. These little marks on the leafs have popped up since yesterday, they can be seen from both sides of leaf. Iv not started on cal mag yet or any epsom salt, I wanted to actually await to see the deficiencies and try learn a little more So I'm hopingiI'm right with calcium def. She was fed water first 3 weeks then I planted 2 biotabs and plain water since. Temp 25 rh 35. I did foliar feed a couple days ago and maybe turned lights on a bit too quick but I don't think it's that. Hope someone can help.
