mother plant care. dynamex

Hi has any one good any good tips on looking after a mother care i currentley just use ph water i had a blue cheese mother and it started turning yellow.I took severall cuttings from her and put them in the propergator.I later then discovered all my clones had spider mites .I didnt even Kno my mother had them as it had no real signs.I have recentley been given a liquid from a friend in the game called dynamex.you simply dilute and spray on two or three sets of leafs it gets in to the cells and protects the plant for six weeks any pest that bites into it will die .Just wonderd if any one else had used this seems to be working great for me.You can even use in flower as lon as it has over 4 weeks remaining
