Yellowing - Form Completed & Pics

I just calibrated it as it's a brand new PH pen. And the RO system is brand new too. My source water is horrible though. 9.5-9.8 out of the tap. I'm sure an RO unit can only decrease the PH so much....

Keep in mind that the PH of the RO water out of the system is 7.5. I PH down'd the water to under 7.0 for the test just so I could see what increase if any there was.

Ummm...are you testing the soil ph with a soil probe thingy, or are you testing water runoff? I've never seen a soil probe that actually worked.

I have a Hanna 98130 meter and a Milwaukee PH55 Meter. I've tested the runoff, and tested a slurry (1/2 cup soil, 1 cup water).

Weez,

You are THE MAN. Moving the light up fixed it all. The widow was a little shy on Mg, but I gave them all a feeding of half strength nutes, and sprayed the WW with some epsom salt water. All good.

Thanks so much for the input. Soil is still a little high in PH, so I'm feeding at 6.6 rather than 6.8 until I bump them up to three gallon pots. I will be sure to check the soil PH before I transplant!

Not so much, it was an easy call.
I had recent, personal, experience with that very problem.
But, mahalo, for da feedback.:)

You are so much welcome.:)
Twere it not "the least I could do" it would nevah get done.:rastasmoke:

So, did the leds not perform?
Are you still vegging with the custom light?

Best

Weeze

The LED's worked with the help of eight CFL's. The 1W ones are a waste of time. Your 15W version is the way to go. It was just out of my budget for now. They'll ease in price soon enough.

I just stuck with the 400W HPS for now. Not even bothering with a Metal Halide, just HPS all the way. Shov does it so why can't I? I had the 120W set up in the veg area, but it brings the temps up to 86. Not ideal if you ask me. With the 400W HPS and only a 200cfm fan I'm keeping the temps at a dead solid 82. I'm upgrading the fan to 400cfm and hope to get the grow area under 80.

Not sure what to do with these two LED lights now. They would do great for a mother plant. Maybe I'll do that. Use the 120W LED to keep a mother plant or two.

Not the best picture, but as you can see the problems are all fixed. The bottom left is a Midnight Kush from G13 Labs. It's been tempermental since it sprouted from soil.

A few more days and up to the three gallon pots they go. They grow so fast. Sitting at 7.5" off of the soil.

Aloha LT.
