The leaves on the sweat cream are yellowing and the new growth on top looks pale.
She drinks a lot of nutes ,every two days I have to top her off with ph’d water. Should I be feeding her more than every seven days in order to keep the proper amount of nutrients in the water?
Could I be starving her? 20190209_182441|374x500
Good. Reservoir size will be something to work with. My understanding is under 5 gallons or so the problem is chasing the PH and nutrient load; particularly in flower.
Are you running anything like Hydroguard? Do you use peroxide? How often do you change reservoirs?
Temperature is good! I see by your range of PPM that it’s probably fluctuating a bit. That goes back to the reservoir size.
You are kind of chasing a moving target with the TDS which makes it a bit more difficult to adjust. The one plant does look like it could use more but new growth is lighter in color too. I would keep an eye on it and watch out for any other signs of a problem.
You are trying to maintain a stable nutrient bath at a stable PH and temperature. So I would be checking daily and adjusting as necessary with a nutrient change no longer than two weeks in veg. Probably more frequently with the smaller reservoir capacity you have currently. Keep good numbers and stay between 600 and 800 PPM and you should be okay.
If i had to guess they’re drinking and taking nutes. When you top off with water its reducing your ppm, and that’s why they look hungry. Keep an eye on those ppm readings and ph like myfriendis410 said and you should be in pretty good shape.
