i'm new as well but got a lot of friends growing and im into my 2nd week of flowering. there is NO hard and fast rule on watering. the way i, and a helluva lot of others, water plants is by lifting them up and testing the weight, lift them dry, lift them wet. stick ur finger in the pot and if its dry about 3 inches down then it needs watered. the plan is to let the pot almost dry then flood it. the plants prefer that. i have six plant all in pots and trays underneath, i give them each 2 pints(1 litre) each and then do it again, and then another pint. this allows the water to penetrate thru the soil . u give them water till u get sum run off appearing in the tray, then stop. my plants need this every 3/4 days. it all depends on size of plant/pot and the amount of heat and growing thats goin on. each plant is different, i got one (la woman) and she's a thirsty bitch. its a trial and error thing.
