Greetings,

I am just finishing up an Early Miss Autoflower from CropKings BC.

Advanced Nutrient ph perfect Grow/Micro/Bloom/Big Bud/Sensizim/B-52.

I had been slowly sneaking up on max nutrients, NOT.

Blew right through and five hours after the fourth feeding in four days noticed my mistake !

A quick flush and 1/4 nutrients and Betty is chugging along...

If I had a PPM meter could I have avoided this mistake, barring any other issues ? And what reading should I be aiming for ?

Here she is at 96 days, 600w MH/HPS, temps 68-78 F, 2 gallon pot, light 20-24" from canopy.

Hard well water @ 7.2 ph. Mix nutrients, ph is ~ 6.8. Ph down to 6.4-6.5. 2 L's was watering to run off but now she takes it all every day with just enough run off to wet the saucer.

112 days.

TDS meter arrived today.

The store bought spring water I WAS using tested @ 135 ppm.

My well water @ 501 ppm !

I mixed up another batch that turned out to be too hot. 50% strength of an Advanced Nutrient schedule off their site.

Lets round it up to a 2L mix :)
Grow 60 drops.
Micro 120 drops.
Bloom 240 drops.

At this point its @ 1620 ppm.

Add 40 drops each of Big Bud/Sensizim/B-52.

PPM goes up to 1723.

So I added another 2L of ph'ed water to the mix, TDS dropped to 1120ppm.

Watered with that tonight :)

Turns out that is only slightly stronger than what I settled on. Judging by whatever lower leaves are left And the top sugar leaves of the buds I'd say we're okay.

If I am missing something, please let me know ! It is so easy to have blinders on and miss something obvious.

Here she is in all her glory two days ago, Betty..

In the image, the top middle section is the end of the main branch I pulled over. Cut off 2" to test and it's still over 9" long with a dozen separate buds.

On the right is a side view of the second branch to be pulled over.

Nice plant. That seems high. That is about what I run my photos at. It's all different, I'm sure, but the last spring water I tested was around 50ppm which makes me wonder. I'd grab a jug of ro water, (usually labeled as purified water I think, will say purified by reverse osmosis in small writing somewhere on the jug) to test your tds. It should read 0. I have 3 and they all vary slightly. Whatever you are doing is working. Beast of a plant.

Thanks Jay !

All I have handy is distilled water and it reads @ 6ppm.

Cheers.
