I hope you dialed in the p.h. of your Happy Frog before putting plants into it. I have some that is super acidic right out of the bag at about 5.0.

Putting a 300w l.e.d. 3in. away from a seedling sounds insane! I'd move it at least 24" away. I'm surprised it didn't die.

I'm guessing micro nutrient lockout. Is your soil p.h. way to high?

Plants look great. Nothing to worry about. Looks like they're getting a really nice flush.

I've never used p.h. perfect but i saw the video on youtube. My guess is that only works best with r.o. water. Tap has too much alkalinity to change the p.h. For example, it only takes 3 drops of p.h. down to lower a gallon or r.o. water a point but like 30 times that to lower tap water a point...

What's water temp.? Are you using a chiller?

Calcium toxicity or defficency depending on what you been feeding.

Try some epsom salt at 1tsp./gal. Your petioles look pretty red/purple?

Your plants look horrible for being 5 weeks old but i'm sure they can be saved... Distilled/r.o. water is the bomb because of the low alkalinity, however, you can't use it without adding 3-5 ml./gallon of calmag+ or you will have a cal/mag deficiency 100% guaranteed! I use 3 ml./gallon of...

I calibrated my ppm and p.h. meter today and did a test on 0ppm r.o. water and got: Fulvex at 3ml./gal. = 40ppm CalMag+ at 3ml./gl. = 135ppm. Fuvex and CalMag+ at 3 ml./gallon each = 175ppm P.H. at 4.5 after adding Fulvex and CalMag+ 6 drops of P.H. up from Botanicare brought P.H. to 7.2 PPM...

Got it. No ground.

I found this manual which explains the setup... http://www.smarthome.com/manuals/zonemaster_install.pdf The transformer has red, white, black. http://cleanairsystemsinc.net/products/Transformer.html How do i hook it up to 3 prong 120v cord? Black hot, white neutral, red ground?

My basement growroom has one register going into it which is on the house thermostat ac/furnace. In the summer i need it open during lights on and closed during lights off to keep my diff in check. In the winter i need closed during lights on and open during lights off to keep my diff in check...

Do not buy that! I bought this on ebay for $65 landed and I love it! 5 AMP 110V VARIAC AUTOTRANSFORMER VOLTAGE REGULATOR POWERSTAT 0-130V OUTPUT NEW

I'm trying 24/0 lights on in veg for the first time and the nodes are insanely tight! When I ran 18/6 they definitely seemed a lot stretchier/leggier. This is with 400w MH. I'm switching to 23/1 today to hopefully get some stretch. If that's not enough i'll switch it to 22/2 or 21/3 so they're...

So it seems like the variac is the best for fans. There's a 5 amp on ebay for $65 delivered. So what can i use my Speedster on effectively? Does it work good on ecoplus water pumps? I'm gonna swap out my Speedster for the variac because my fans do hum pretty bad when dimmed down. I just want to...
