Hi all, I'll try and keep this brief as I can and please correct me if I'm wrong anywhere.
I've been growing 12 Sweet skunk autos in 15L pots. Here is my setup:
I have been following Tang's easy auto feeding schedule for 3 grows. I noticed some problems with my plants in the first grow and some suggested it was either a pH issue or the hardness of my water (which is really hard)
So I got an RO system to eliminate the hard water. I also got a pH pen to test my soil and water.
I found the pH of my feed and soil were around 5.5-5.7 - too low for soil grow (?) So I started to adjust the feed with pH up to try and get the correct pH in my pot. I didn't manage to achieve this, the pot was always < 6 pH.
I then found out that one of advanced nutrients big selling points is it's "pH perfect" and buffers the feed to the correct pH, which turns on to be 5.5
So after some more reading, that pH of 5.5 is for hydro grows and the pH you want your resivour. Not the pH for soil grows which want to be 6.5-6.7
Therefore I think my initial problems, that I'm still suffering were likely pH issues.
Now for the advice I need. I want to change nutrient brands and adjust the pH my self. I don't want thousands of additives, just the basic my plants need. Can any one recommend a brand for autos? And preferably a feeding schedule to go with it.
Also, as I now have Reverse osmosis, I need to replenish with calcium and magnesium. Should this be done with calmag supplements in soil or should I use lime?
Long post I know, and I appreciate any advice you can offer.
Cheers!
I've been growing 12 Sweet skunk autos in 15L pots. Here is my setup:
- 2*2*2 m tent
- 3 * 600w HPS bulbs in cool boxes and 5 inch fan
- Isomax extraction fan (plenty big enough)
- 12 * 15L pots Bio bizz ilight mix soil
- Advanced nutrients as per Tangs easy feed schedule
