Drooping, light or other?

[JohnWA]

Ok so here is one of 2 plants I have on a fog setup, the other plant is fine but this one is starting to droop. I am thinking the drooping is coming from the fact that the lights I have above it are 4200 Kelvins and the ones that are pointed at the sides are 5000K. Now I have a 3rd floating light that I switch between plants every other day, and yesterday was this plants day for the extra light.

Do you think its just the gravitating towards the extra side light, or something else?

what kind of grow is it? hydro?? if its hydro whats your ph and ppm?

 

[JohnWA]

technically, it is fogponics.

PH is 6.3ish, and PPM is around 400.

 

[JohnWA]

that was last check 2 days ago. Now my PH is 6.0 and PPM is 1500.

 

[Jimmycricket]

Well 1500 ppm is almost certainly too high.

Also you should use 6500 or 6400k lights not 4200k for veg.

 

[JohnWA]

I have already put these into budding.

how do I lower PPM?

 

[Jimmycricket]

then you need to use 2700k lights 4200k is too high for budding properly.

Add more water to dilute your ppm.

not to mention anything above 6.0pH is no good for hydro

I'm. sorry. I told you my lights wrong.
overheads are 3000k and sides are 2700k. ph of 6 is no good, really?
I've read everywhere 6 to 6.5

I was under the impression that 5.6-5.8 was ideal for hydro but i guess thats one of those things that is always different for people

EDIT: "I follow and highly recommend the following parameters for hydroponic nutrient solutions for aeroponic, “bubblers”, drip, ebb and flow, NFT, passive, rockwool and wick systems.

PH 5.1-5.9 (5.2 optimal)"

What levels should I maintain for my hydroponic nutrient, temperature, pH and TDS/EC?

 

[JohnWA]

+ reps, thanks very much.

a mod can delete this thread. Problem solved.

BTW, solved it by doing nothing. I simply added a light, but now that I know PH is supposed to be lower I won't be making it so high for future purposes.
