Plagron Allmix is a good choice for a beginner and it’s organic. The lightmix is synthetic and is weaker so you would have to feed more. I tested the soil ph of organic plant magic, biobizz lightmix and a lightmix from Intense nutrients. They were all surprisingly acidic, about 5.6-5.8. But plagron was higher above 6 (greenish if using ph test kit, opposed to bright yellow for the other brands). The ph range is vital, the plants will grow with vigour and use the available nutrients when correct. Plants will lack lustre and look partly deficient when using acidic soils, leading to people thinking to use more fertiliser. They also tend to develope magnesium deficiency a few weeks in. Calmag will help but the problem will persist, even mixing dolomite lime doesn’t totally correct the problem as it takes time to break down. So it’s very important to start with a soil that has the correct ph. The plagron brands had the correct ph levels but the ec levels where off the scale, ec truncheon flashing rapid at 3.6. In my opinion we have been getting ripped off for years, buying inferior branded soils. I suggest mixing a good quality lightly fertilised organic soil with coco, charge (blood, fish and bone as an alternative), dolomite lime and bat guano. All mixed at lower dosages to what’s recommended. Then just water, occasionally with enzymes and a couple of microbe teas. Only when weeks down the line when plants show signs of using up the nutrients do I make the girls a bat guano tea lol. If you use bottled fertiliser like I do at times, use organic (it’s brown and smelly) opposed to synthetic which is clear and pretty much odourless. I started out using organic feed, but then used synthetics for years. Then I started flavour chasing and went back organic and it’s true what they say about taste. All the best, just remember to feed lightly.
