Its better to under water then over from what i hear. a little drier i herd is better Makes them roots search for water and grow. but to dry and they die. Over watering drowns the roots and they can’t breathe. if i over water I like to put a fan on the pot to dry it out faster and add some humidity as well. Your girls would be alittle happier with like 60 at there stage. At least thats what i shoot for I do 40 to 50 in bud. But it gets lower sometimes as the cold air kills my humidity. Lower humidity will dry that pot out faster as well. It will be good. Never killed a plant yet and done over water many times. Still got bud and they still grow. Thats the beauty of these plant. They just grow.
