Michkaanswered grow question 6 years ago Hello ! Your temps are good, but you humidity level is too low, you have to manage this, 70% would be perfect. PH must be in a range between 5,5 and 5,8 at this moment, don't water too much, half a liter is ok but maybe every two days would be better.. The yellow leaves comes from a nitrogen deficiency, next wattering put a little bit of grow nutrient and for the rest everything's looking right ! Feel free to ask if you have another question, hope i helped u ! Happy growing!
