Once this plant can be seen i would change the grow medium,can't realy see much yet bro just don't over water but do mist the root base at least twice a day this will keep it happy.the trouble with only you knowing about your grow op is that you never seem to see a differance if growing in soil.that is why i do both hydr shit one day the plants are 5 cm the next there 8 cm.but you will get there but future growing use soil if that is the only option that or the order some rockwool cubes online or at thelocal hydro shop.
