Ph in soil when feeding sythentic nuteients

Soil balances its self in almost all cases if it is truly soil, It also holds onto a lot more salts then other mediums, hard to flush it with out it being water logged. less is more. If you need to alter soils PH do it with sulphur or lime more so then by adjusting ph in water. Good Luck!

You should always ph your feed and water. Most cases the soil is slightly acidic, most plants prefer it.

a good "synthetic" should be ph-buffered. consider a different brand if it is not.. saves a lot of needless headaches.

yes u need to buy 3 in 1 Measure Soil pH Level, Moisture Content, Light Amount Soil they cost around 15-20 eu but if u mixing nutriments is better to mix them in water and after water the plant with that water or they are some nutriments who u just need to place on the top of soil and with every watering they go down
