The newest addition to the Plant Magic Oldtimer range; Organic PK 4-8. Designed to work harmoniously with Oldtimer Grow and Bloom, PK 4-8 delivers an extra boost of organic potassium and phosphorus to your plants. This promotes greater yields with denser and more abundant flowers.

How It Works

It is well known that raising the levels of potassium and phosphorus during the bloom phase can greatly help to increase the yields of flowering and fruiting plants. However this can become a somewhat tricky process if you are trying to do it organically! Fortunately the clever guys at Plant Magic have worked it out and created a very near, fully organic PK flowering booster. The added phosphorus will produce exceptional harvests and increases production of essential oils, it is also required for the uptake and transportation of key nutrients as well as boasting beneficial effects on the ripening process. The extra potassium makes for ripe, colourful fruits and increased BRIX level. 

How To Use Plant Magic Old Timer Organic PK 4-8

Oldtimer PK is best suited for use on soil-grown plants. The Plant Magic feeding schedule recommends it's use around the last 4 weeks of the flowering stage at a rate of 1-2ml per litre.

As with all organic products we highly recommend using Ecothrive Neutralise to remove potentially harmful chlorine and other contaminants from your water and therefore maximise your results.

Unlike some other organic brands on the market Oldtimer PK is able to be used in automated watering systems including drippers. However extra care and attention should always be taken to check for blockages in your pipework which can still occur. Always use a recirculating pump in the reservoir when using organic nutrients to help prevent this.

Oldtimer PK is best combined with the other organic products in the Plant Magic range; Oldtimer Grow and Oldtimer Bloom.

Plant Magic Oldtimer PK 4/8 is available in 1L and 5L bottles.
