Jack's Two Part

In hydro the Jack's two part (5-12-26 plus the 15-0-0) is amazing. No need to switch formulas between veg and flower, just keep the PPM's 500-600 (1-1.2 EC) and you're good. Super easy to mix ( it's called 321 for a reason), 3 parts of A, 2 parts of B, and 1 part epsom salts (Walmart's brand is OK and cheaper than Jack's). You can mix the Part A and epsom together in water but carefully add the Part B, it can get cloudy. PH 5.6 to 5.8 in veg and 5.4 to 5.6 in flower. That's all you need for the simplest and cheapest crop you'll ever grow. Since I switched from Gen Hydro to Jack's my plants are happier.
