I'm growing in coco, so my set-up isn't exactly the same as yours. But it's hydro and I water twice a day 'till there's significant run-off.

(I love how I learn new things on this forum every day!) I don't pay much attention to ppm. The plants dictate what they want, not the numbers on a chart. If you want to record the ppm #s for future reference when growing the same strain, that's great. But right now your plants don't much give a damn what your ppm meter sez.
Is your plant a clone or seed? Where are you counting that one-month age from?
Here's the protocol I follow: When the roots on the clone look like the first photo, I put them into either a 3" rockwool cube or an 18 oz. cup with coco. They are then put on B1 & tiny amount of Superthrive for the next few days while they get used to life outside the dome. After that, I mix AN M-G-B as per label directions (2ml/L) & CM+ @ 3ml/gal and start with a 1/4 strength solution. From then on in, I let the plants tell me what they want. 1/4 strength lasts for a few days, then I up it to 1/3 or 1/2, depending on what the plant wants. You increase the nutes in this manner until by about the third week out of the cloner your at full strength. For weeks three and four they are on full strength nutes and, when the plant says "hey, I really want to grow now" I start adding molasses and Sweet. When I add the molasses & Sweet, I do not cut back on the other nutes just to reach some arbitrary ppm number. As the plants get bigger they use more of the nutrient solution - they drink more - but the nutrient strength stays the same.
When you're in flower and you're trying to pump the plants full of as many nutes as you can without killing them, I suppose you need to use ppm's to some degree to regulate things in your hydro system. But your benchmarks are dictated by your strain and your plants; not by some chart.
Enjoy your grow!
Never argue with an idiot - they drag you down to their level then beat you with experience.
All of this is just pretend. But if I grew marijuana, it would be in strict compliance with California Law, SB420.
