Heres a handy ppm to EC chartI freaking won that hannah ph/ppm combo meter for 66 bucks/ it retails for 200 new. I broke my last tds meter and took it back. Ive been quessing. and I think I should be adding more too! I will in a few min. Now that you said that. I was wondering what is holding the other two from sexing for me. They are swelling and about to show....will u please use the ppm equivilent(1.7 what). I dont want to convert? My PH is 5.4 I just checked it.... I also have to add more water. they have been thirsty....

1.7 Ec on a hanna is 850ppm
Going on the greenhouse company's grow guide on Youtube for WW they say never go about 1.7 to 1.8 EC.
I'll be changing my res Wednesday and hopefully it will manage the week with out any adjustments. I'd hate to come back after a week and see my plants dead.
