Pablo Escobar first time grower

Abit of a shocking week this week, finding male flowers on the one plant, I went through it carefully and pulled about 8-10 balls off, apparently this is common during first weeks of flower , I'm hoping that's all I'm going to have to deal with. almost ripped the plant out straight away , I'm going to monitor it for a while and see how it goes. still using 70% recommended solution and my run off is about 0.2EC higher than what's going in so I'm going to keep it like that thanks for viewing :) any advice much appreciated
