Temp within 22-29C range but humidity a bit lower than 55-60% range because sharing with another plant at week 5. Started to water a bit more and started LST. Also after 2 weeks of fresh water have started to add growth complex as plant bug enough. Continue to keep even PH. Started to see yellow spots on leaves, was either mould or calcium deficiency; didn't spread so likely to be Ca deficiency which nutrients should correct.
