Indoor Promix, what should be added

[jhnfrmrby420]

Here's the recipe I've used in the past:

4 gallons Pro Mix
1 gallon worm castings
1 gallon perlite
4 tablespoons blood meal
4 tablespoons bone meal
8 tablespoons kelp meal
4 tablespoons epson salts
Dolomite lime or sulfur as needed to adjust the pH.

This makes approximately 6 gallons, enough for two 3 gallon pots. I also add 1/2 teaspoon of mycohorrizal fungi to each pot when I transplant.

I've moved away from this mix and am now using straight, unamended Pro Mix, mainly because I can't get bulk worm castings anymore. I'm now supplying all nutrients through feeding.

Thanks very much there Muddy, I greatly appreciate it. When I go near true value I'll take a pic to make sure Im buying the right one.

When I order the new fan next week I was thinking of getting some Dutch Masters Liquid Light Foliar spray and the penetrator to go with it, does anyone have any input on this? What other things should I order to take care of certain problems, dont want to go crazy funds are tight

Hey Muddy with that recipe, would I still feed nutes or just water with mollases???

 

[Muddy]

You will still probably need to do some light feeding, especially in flower, probably not more than 1/4 strength. I would also suggest you keep a bottle of cal/mag supplement and a bud booster like PK13.14 on hand in case you run into any cal/mag or P deficiencies.

Cal Mag is basicaly molases right? I give it to them with every watering/feeding

 

[Muddy]

There is significant cal/mag in molasses, along with sugars and trace elements. The ppm of the rain water I use is very low, so I've got to add 1/2 teaspoon to every gallon of feed to raise the ppm to the point where my solution is buffered properly. If you do run into a cal/mag deficiency a cal/mag supplement will be faster acting than molasses. If the deficiency is severe it can be applied as a foliar spray so it's even more fast acting. For about $10 a quart, IMO it's well worth it to have it on hand just in case.

Thanks Mud, I guess I'll order some to have on hand

Muddy, You talked about changing your pH to 6.2. What did you think of that?

 

[Muddy]

I've done a lot more experimenting with the pH of Pro Mix since I wrote that. I did find anything below 6 didn't work very well. 6.2 to 6.6 seems to be the best range. I'm now adding 4 grams of 17% aluminum sulfate per gallon of Pro Mix and feeding at 6.5. My pH drops to 6.2 the day after feeding and slowly goes back up to about 6.6 as the plants dry out. This is allowing the plants to cycle through the desired pH range and my results have improved but more importantly, the pH has remained stable.

i dont like adding anything to it other then extra perlite and only do that sometimes as it requires more watering and i rarely have energy to do so

but as said , i dont add anything because each plant has its own needs , i like to let the plants tell me those needs and take care of each , its harder with big numbers , but only 4 or 5 from 150 or so ever need special attention when growing a fairly uniform strain

peace :Cool:
