Hi guys. Every few days one of my plants lose leaf and they looks like on photo. All plants are on Perfect condition, have a problem only with that one. Is that a mould ?

Ik zou liever hebben dat je je plant preventief behandeld tegen meeldauw. Het is een samenstelling van water en melk, je doet er niets verkeerd mee. Zoek even op het internet de gedetailleerde informatie op, "behandelen meeldauw". De bladeren die te zwaar aangetast zijn, moet je verwijderen. Beter om zeker te zijn🙂

De all mix is op zichzelf al stevig voorbemest, daar kan je meestal wel even mee door. Op vlak van voedingsstoffen doe je niets verkeerd, de Biobizz voeding blijf je allemaal geven tot "het einde" -> spoelen meerekenen voor de oogst, als dit een voedingsoverschot is. Normaal hoef je bij biovoeding niet veelvuldig of gewoon niet te spoelen, tenzij je wat problemen had. Het heeft voor mij op 1 foto wel wat weg van meeldauw, maar dat kan ik niet met 100% zekerheid zeggen. Zag of zie je ergens witte poedervlekken die je wat kan wegvegen?

I would check first the PH and the PPMs on your run off water. I had a problem with calcium deficiency just because the PH pen wasn't calibrated and was around 5.3. If those values are ok then I would stop adding nitrogen for a while and see how is the new growth

You mean I gave much nitrogen nutrients ? Should I use only water on next few waterings ?
