Help kids may be dieing

[daihashi]

OK so i have the same 2 widows i posted about ealrier, but now i moved them under a 400w HPS. The one that was thriving now has droopy leaves. also just a bit of light green in the top of the plant. I have them in 7 gallan res.


-Temp= 77 F
PPM=1730 - i just got the meter and dont know how to use the information fromit yet.
PH= 6.7
-8 drops of superthrive- i think i put 1 extra drop on accident
-CO2- i have CO2 on 7 times a day 15 min each time, i will increase whenthey are bigger but i wantto save them for now.

PLease tell me what to do to make them start thriving again. Thanks any help would be great.

Your ppm is way too high. I believe you want below 1500ppm

Your PH is way too high. You want about 5.3-5.8 for hydro and 5.8-6.3 for soil less. 6.3-6.8 for soil.

Don't even bother with superthrive. It's great to help plants out of transplant shock other than that it's one more additive that can just make troubleshooting complicated.

How much CO2 do you have in the room before it is evacuated out? The stomata will actually close if there is too much CO2 inside the leaf. This causes photosynthesis to come to a screeching halt as well as your plant growth.

What is your resevoir temp?

77 degrees is good ambient air temperature for the plants (this is for your plants.. not resevoir. I'm not sure what the resevoir water should be at.
