To feed or not to feed? Need advice

My babies have hit 1 month old and need watering today. One is in Happy Frog and one is in Oceans Farm. 3 days ago when I watered the Ppm on runoff was between 800-1200 and they are in flower now. I am using Jack’s 321 and was debating starting the routine now. What would you do?

With grow info and pics you’ll get some answers.

The 2 in question are the smaller bushier ones.

What was the reading between 8,1200exactly??? Its important. I start at readings at between 8 and 1000 depending on the plant. Would like to see your girls in beter kight but they look good to me.

My vivosun tds meter is hard to get a real reading. Depending on how deep I put it in the water depends on the reading I get. I usually try to go in middle for instance if I touch the sensor into the water to where it’s reading solid number it would be 800 for instance but if I stick it way down where the other side ( not the probe but the other whatever it’s called) is in the water like an inch or so it will be higher. I would say they both read about 1000

Going in the middle of the lowest and highest reading

OK, I started Jacks 321 at 1/2 strength, after only 2weeks in Coco Loco which is Coco+ soil by Fox Farms. Here they are at 4 weeks:
The stuff works great!

Perfect I’ll start with half strength and see how and if they react. Do you use Jack’s every watering?

What is the medium?
I use coco and feed every day. If the pH or PPM are off, I will go with pH water first and follow that with Jacks.

Thanks for bringing that up as i do use soil.

Watered and did full strength Jack’s mix towards end of runoff they were all right around 1000.

That is the conventional formula and what I started with. The GDPs in my thread GDP to start the new yearget what I call the Hybrid Formula. More Part A and less Part B. I use it because of my well water being Calcium rich.

The one headed Jack’s Nutrient Schedule is the rates currently recommended by Jacks.

I use the MKP formula the first 2 - 3 weeks of flower.

@Newbie84 , sounds reasonable to me. 1000 ppm runoff sounds right. I’m at week 8 total and week 2.5 in flower. For the past 3 weeks or so I’ve used @ 3+grams/ gal. Part A, 2+Grams / gal. Cal.Nit. And 1+gram/gal. Epsom…3,2,1.easy to remember. Then I’ve added 3TBSP/gal. Espoma organic Cactus Bloom. And I will add Jacks finish feed for the last few weeks. My plants are outgrowing my tent and very vigerous. Yes every watering. I did one flush after week 4 but my run off is still running low so onward and upward.
