So here is my nutrient schedule this run for the MPB only. The coco got the same nutes (brand, ppms etc), but I have been watering a little different. The coco get a 40 gal res full of food (same as the MPB). That lasts them about 2 days giving them about 3 gallon each/day on a short cycle timer. Then they get another res of food. Then they get a res full of PH 'd water. SO: FOOD x4, water x2, repeat.
For the MPB:
Weeks 1-4 :
JR peters Hydro at 2.9 grams / gal.
Epsom salt at 0.1/ gal
JR peters CaNO3 at 2.0 grams/ gal.
I sprayed at week 4 with calcium25 because that's when I found out about it, but I will be spraying my plants every week veg---> week 4 flower from now on in all of my grows.
Weeks 4,5:
Same as above, but added ROCK RESINATOR () @ 1.5 mL/gal, for a K boost and to continue adding tricontinol. The rep at the max yield convention told me that was what ROCK had in it, and gave me a bunch of free samples. Since I cant spray with Ca25 anymore, I add this.
I am not sure if I will change the formula now to get closer to a 2-1-4 to get rid of the N the last few weeks of flowering. Any input on this from someone who is familiar would be welcome!!!!
Also, I was doing add backs of pure RO, but stopped that 2 weeks ago. Now I just let the plants drink and monitor the ppms and pH. Once the pumps are about to start sucking in air, I change the whole thing out. This has been around every 4 days. I feel this is a better way of doing things, since:
1) I know how much they are drinking
2) If the ppms stay around the same I know they are eating enough
3) I do not fuck with my ratios this way at all.
My pH drifts up to 6.5 every day religiously, and I drop it down to 5.5.
Finally, and this is something I forgot to add here when I did it:
WHEN I ADDED CO2, I AM ONLY RUNNING 800 PPM. I READ THAT ANYTHING OVER 1000 is a WASTE. I AM SAVING 1 TANK FILL A WEEK THIS WAY.
