I am using the happy frog, and right away I started getting calcium deficiencies. Checking out this post and seeing that the main difference here was the tap water. the Ph'd tap water is the key to unlocking the happy frog, without the calcium in the tap water, the plants will suffer. I have been using RO and discovered that, I have had to use cal-mag+ to compensate, and I added some ff grow big. I want to try to mix the happy frog with the ocean forrest but i feel like theres not enough in these soils to get monster buds you are the only one ive seen using only this soil and get this result.
For a minute I thought that was some exotic Photoshop filter, but I gather that's the pretty purple light from the LED ... which obviously works very well plant-wise !
