Hey Birdu2, I noticed your leaves look wet in your day 8 photo. Because your humidity is so high, you might want to water the soil slowly so no water splashes up on the leaves. Wet leaves encourage fungus/mold/bacteria
Thank Bubba, i didnt know what was the cause of those brown spots .... and send the pic to Mitch, and we agree that was caused like you said, by the splash of water when feeding during the morning and the drops left in the leaves burn the leaven becouse of the really intense and stong caribean summer sun
