How many PPM's in a half dose?

 

[Aqua Man]

Ok so would you recommend me going full nutes, have yet to go above half nutes EVER.

No stay at around 600ppm.

What are you using to control alkalinity and createa stable PH? Using RO you have 0 and most cal mag does not add alkalinity so I would assume you have a large PH swing daily. Like going from 5.6 to 6.0 in a day.

100-150 ppm is about ideal. That would depend on the brand

No more than 500 plus my cal mag, which I use at 3ml per gallon. Giving me about 650 this water change.

Ph seems to be pretty stable, I usually have to bring it up with GH PH up and that does the trick for a few days until the water level starts falling. After adding nutes it’s at around 4.5 ish then I ph’ed to 6.3

Sounds about right... the fact you need to use PH up tells me alkalinity is to low. In the future potassium silicate is a great addition not only for alkalinity and PH stability but silica is a huge benefit to the plants and the bump in potassium is also nice.

Not sure if I linked this for you before but if doing hydro its something I suggest reading.

Marijuana pH Levels for Growing Weed: A Basic Explanation

OK I'm going to do my best to explain PH since its something that is for the most part greatly misunderstood and can be confusing to new growers and even experienced growers alike. This will explain why we need both ppm and PH meters to give us informed information about PH This will be a...

Can't you use PH Up to raise waters PH.

I figured I couldn’t be doing this completely wrong but this is only my second grow.. but yes next grow I plan to add in silica blast during the early days of veg. As far as bloom boosters, should I throw in Hydroplex alongside my Base nutes this run if I start to see signs of deficiency’s? Or just bump the strength from half?

Yup but should be added first. 75ppm of ph up gives a good alkalinity to start with but potassium silicate is a better option IMO silica is soooo important

Only thing you might want to add is some epsom salts. I find cal mag usually about a 5 to 1 ratio of calcium to magnesium and I like aboit 2:1. Late bloom 2g per gal for the added sulfur to help bring out the terps. Start to finish 1g per gal

I was just turned on to "massive" by green planet by @Dirtbag and after a lot of research im giving it a go. Not heard one bad thing about it. It also contains natural PGR. So if I was to change anything I would go with your grow nutes and sub massive instead of your bloom

Just added it to my cart will try it on my next grow to compare alongside some silica blast from botanicare, but going to opt to doing half grow half bloom nutes for this plant and post back. Res change is due

Sounds like a plan.

I’m assuming she’s done stretching and is just budding now. Front of canopy

 

[REDBUD46]

i guess it will stretch a little more as the buds full up...if it was me id trim below line

 

[Growrx]

it’s been 9 days since the last water change, a little over due.

10/21 Seedsman Northern lights
20ml Botanicare PBP grow
20ml Botanicare PBP bloom
9ml Botanicare Cal Mag
6ml Botanicare Hydroguard
6ml Sensizyme
PH- 6.2
PPM- 775

Added cal mag to the water first to get a read and it got me to 165ppm from 0. Let’s see how she does with the 50/50 veg bloom nutes.

 

[Growrx]

Checked ppm today and it dropped to 715. she’s definitely taking up nutes, but is that too big of a drop?

 

[Growrx]

Went ahead and really cleaned up the bottom of the plant

Swapped out my 600w phlizon for my 1200w phlizon that I just removed from my other tent that is being chopped tonight. Hoping to give her a little more life before her time comes.
