Coco peat perlite,half-dose Terra aquatica 3part everyday about 100ml, 89temp 50%RH, day 13 now they started showing slight yellowing on top leaves edges. Should I increase the nutrients to full dose? Or correct my pH (5.8)? Water less? What should I do? Thanks!

This is magnesium deficiency. Not over watering. Coco retains air plus the perlite. Also light might be too intense. Plus it's still too warm. One of the downsides of coco is it needs extra cal mag to grow in.

Thank you guys for the answer! I have no access to calmag supplements where I live so I’m just gonna buy some epsom salt and add it to my nutrient water!

Das interveniale Ausbleichen hab ich auch feststellen können. Aber diese gelben Zacken an den Blättern. Bist du dir sicher, dass das nur von Mag-Def kommt? @Roberts

@Terp1 Thanks for your answer. Leaves aren’t dropping at all though and I was told coco should always be kept wet and watered everyday with nutrients. I give 100ml once a day so I’m confused.

Weniger Wasser. Das sind Anzeichen von Überwässerung bzw. können deine Roots kaum atmen. 😎
