Seedling PPM

What's a good ppm for 2 week old seedlings? Right now I got it at 175. Using GH Flora series in 5 gallon buckets(DWC). Any advice is much appreciated.

at 2 weeks im at fullstrength seedlings and cuttings stage around 540 ppm

Thanks for the response. I am going increase. The roots do have feeders developing.

If it was me, I would start slow like you have done; watch the plant for stress and slowly up the ppms till you’re feeding a healthy growing plant. All plants are different; it’s better to under feed and have slow growth than to over feed and burn the shit out of a plant. 540 ppms seem a bit high for the start of week 2 but it could be a heavy feeder strain and yours may not, work up the ppms and study the plants. Live and learn.

I agree, I'm not going to jump that high. Usually increase it 75-100 ppms and watch for reaction. According to the reaction ill adjust as necessary. It's a multi-strain grow so each one is different. Just want to hear what is the average ppm from other growers at this stage.

If you don't know the strain then start low and then add. Mine go straight from cloner to veg with 650-700ppm and never a problem with 14 different strains. If doing dwc i keep ppm at 550/600
