Yup. I should have added some perlite, but it’s too late for now.

I guess I watered too little. I did it in 3 steps:

• 1. spray dampen the top soil with water
• 2. pour one half of the water with fertilizer
• 3. pour the other half.

That way, there was almost no run-off.

I use BioBizz BioGrow (an organic fertilizer, but also feasible for hydros), but it turned out: in too little quantities, too.

The first inch is bonedry, but it’s damp below that. Soil moisture is about 40-50%.

Apparently, my plants have all kinds of deviciencies. I should have used more fertilizer and better soil. This is almost pure coconut.
