Blackberry Auto & Stardawg Auto SP250

Everything going well so far, we didn't encounter any problems yet, but will cut down on the watering as in only watering when the top inch dried out. UPDATE (16/11): The problem with over-watering turned out to be true as minor spots with algae appeared over the coco, now we water every 2 days, maybe more for the plants closer to the humidifier. We did some more research and found out is not a good idea to let coco to dry out completely, especially an inch.. we will try to water when the color changes from dark to brownish. Also, the leaves started curling recently and we think it is because of wind burn so we turned the ventilator to not blow directly on the leaves. We will see in the following days if our hunches turn out to be true. UPDATE(19/11): The leafs are a kind of droppy and we think it is because of over-water again...can't seem to find the right schedule..it's so hard to be a beginner. Also, we added the second light in the tent and now the temperatures raised to 28-30 degrees... probably also because we lowered the light to 45 cm as well.
