Alright, Two of my plants seem to be doing ok but the other two are having a little trouble... I will post pics but mainly, they are pale green and yellowing, and somewhat droopy, they also have little brown spots on the tips... heres what we are working with..
22 days old
light 18-6
ppm 558/ flora nova
ph 6.08
co2 1500ppm
temp- 82
humd- 53
does anyone have any idea what will help? I also have more pics if you need more specific pictures to make a better diagnosis..

what kind of nutes are you useing? and how big is your root system? also what kind of set up? is it a DWC?

85 is a little high for your temp. are you venting well?

 

[fifthambasador]

FloraNova, and it is a dwc... we probably have a 50 gallon tank where the roots are... and we dont have any ventilation other than us opening the door a few times a day...

i haven't even looked at the pics, no need. at 22 days, you should be at full strength. that's why they're pale and yellowing, they're hungry for nitrogen. your ppm is too low, and your co2 is too high, so is your ph. in hydro, you should be around 5.8.
