IMO it looks like there underfed... also i dunno how far your lights are but your may want to put them a tad bit closer

I'm not really seeing anything bad... some light glare of the flash is what I think to be seeing...???

Overall, they look pretty darn healthy & happy... like they are getting through the transplant & the roots are starting to take... the new growth looks nice & stretched outwards, so...???


You say 480ppms... do you know what the EC is? Cuz if you have an 1.0 EC conversion to 700ppms, then you are running a low solution & might want to consider bumping it up. If you are on a 500ppm conversion, you are at a 1.0 already, so just let em grow out bro.

Yea those look really nice! I agree with what mlway said maybe bump up the nutes the green does look a little light but other than that nice set up

cal mag

I agree. Cal-mag issue.

Increase the presence of both. You might be using a bit too much potassium, or there might be a little sodium in your water.

Either way. Cal-Mag.
