## Features

- What is pH pH tells us how Acidic or Alkaline a Liquid or Solution is. Specific nutrients require certain pH levels for plant uptake. The wrong pH level can result in too little or too much of certain nutrients.
- When we need pH Up SOLUTION when the pH level drops below 5.0, plants can develop magnesium and calcium deficiencies. This point of time we need to add pH Up. *PLANT SYMPTOM WHEN pH IS LOW (A) Stunted growth B) Dark green leaves tinged with red, bronze or purple C) Brown spots on leaves D) Leaf necrosis E) Withered, stunted or twisted leaves Leaf (F) Tip burn (G) Blossom end rot in fruit (H) Leaf chlorosis (where the leaf veins remain green but the rest of the leaf turns yellow).
- When we need pH Down SOLUTION - pH level is high can prevent nutrient uptake and lead to deficiencies. Plants only take up dissolved nutrients through their roots. If pH is high Iron(Fe) are less soluble and unavailable for uptake by plant roots, resulting in restriction of new growth and overall stunting.At this point we need to add pH Down. * PLANT SYMPTOM WHEN pH IS HIGH - (A)Tip death of new leaves (B)Stunted or wilted leaves (C)Spots of leaf necrosis (D)Blossom end rot in fruit.
- How to use CityGreens pH Up & Down Nutrient are HIGHLY CONCENTRATED start with 1/2 ml to 1 litre of water wait for a minute than add another half ml till you achieve the desired pH. pH Down -1ml lower pH by 3-4 points. pH Up - 1ml increases by 2-3 points.
- For AQUARIUM - Yes it can be used for Aquarium as well. Support Team We are known for our best customer support Our support staff is available Monday to Saturday on Phone and Whats-app.
