Pale older leaves? Stalled new growth? Those are the usual first signs of a nitrogen shortage, and Growhard Nitro Boost is made to put that right. It blends fast-release and slow-release nitrogen, so plants get something to use straight away plus a supply that keeps going after the first feed. Growhard sum it up as fast release, rapid growth and improved yield.
Nitrogen is a building block of proteins and chlorophyll, and plants lean on it heavily during leafy growth. Short on nitrogen, a plant makes less of the machinery it needs to grow, and delayed early crop growth is often traced straight back to this.
Why do the older leaves go first? Nitrogen is mobile. When there isn't enough to go around, the plant pulls it out of older leaves and sends it to new growth.
Here's the sneaky part: a shortage doesn't always mean too little went into the tank! In a recirculating hydroponic system, poor oxygenation can cause denitrification, where bacteria in low-oxygen conditions convert nitrate into gas that escapes from the solution. In run-to-waste organic systems, the microbes breaking down organic matter use nitrogen for themselves and can deplete what's left for the roots. Either way, the feed on paper and the nitrogen your plant can actually reach may no longer match. In systems like these, Nitro Boost is an economical way to put the shortfall right.
It tops up the nitrogen, but it won't remove the cause, so in a recirculating system check your oxygenation as well. Pale leaves can have other causes too, such as a pH or root problem, so rule those out first.
