Product description
Atami ATA PK 13-14 1 L – PK bloom additive for a home grow tent
A litre of PK 13-14 is the standard size for a tent at home. Because the dose is low, this bottle easily lasts several flowering runs.
What it is
Atami ATA PK 13-14 is a universal PK bloom additive: 13% phosphorus and 14% potassium (w/w) on top of your regular NPK base feed. During flowering your plants need extra P and K for flowers and fruits, and this delivers it in soil, coco or hydro. You can add it every day, from the first week of flower, at 0.25–1.5 ml per litre.
How far 1 L goes
The dose range is wide, so is the yield: at 1.5 ml/L one litre treats about 670 L of nutrient solution, at 0.25 ml/L it stretches to 4,000 L. Most growers sit somewhere in between, depending on plant and phase.
Start low, build up
Begin flower at 0.25 ml per litre and raise it gradually over the following weeks, so your plants can adjust. For a 10 L watering can that means starting at 2.5 ml. Check EC after every mix. In the last week before harvest, flush the medium with plain water and enzymes.
