i mean i good bit...like i couldnt say exactly cus i use my homemade...hydroponics/watering system to hand water...basically so i dont have to go get water and make it exactly right every time...so basically when they are dry i water them enuf to the point where prob every bit of the soil is wet. ima put some pics of tomm of all the plants outa the growin environment i took some pics tonight out in my living room where u can see them better but im to tired to put them up tonight..so check back tomm and see what u think...i seriously dont think its underwatering but im not sure exactly why they seem to be up and down depending on the day...the water i use is exactly where it should be no chlorine ph is exactly at 6.8. but like i said i left the water in the resivoir there to long and it looked merky and nasty and i think that was half the problem..so now ima keep changing it weekly if not earlier. gavem all nutes today just to make sure that wasnt the problem cus i havent given them nutes in like 2 weeks. because i didnt wanna over do it....so ill see how they do in the morning and post the pics i took tonight and then the ones in the morning after i wake up...check back tomm and tell me what u think
