Brown spots on leaves

PH should be at 5.5-5.8...and with cocos u must watering with 20% drain

Does your substrate have green spots like mold apparently? I've had the same problem as you, and it's always those green mold-type fungi, excess humidity + heat. The solution is to use acidic soil on top, lower the humidity, and only water as needed. Also, I just started using rooting agents like Mycorrhizae, Trichoderma, and microbes to protect the roots from possible outside pathogens.

Hello.. Hope you are well.. Just had a quick look at ur dairy n noticed ur giving her 0.5ml per litre of a&b.. Give her at least 0.8ml on nxt feed.. Also if u want u can raise ur rhizotonic up to max 2ml per litre atm.. U will definitely note a difference in few days.. Keep eye on ph values as additional nutes mite drop ph and ur rhizotonic will definitely raise it so check value b4 watering.. Stay safe n gud luck.. 👍🍀

Been feeding at a ph of 5.7-6.2 changing it by .1 or .2 daily, yes think i overwatered at the start which has cause abit of algee in placea
