I am growing strawberry diesel in soil and I am currently starting my 4th week of flower. I have noticed yellowing on the edges of my leaves and some in the new growth lately. I watched my PH closely and usually water at around 6.5. My plants didn't have an easy start and were stressed but I brought them back beautifully. I noticed 3 days ago I had what appears to be white flies having seen only a few of them. As seen in the pictures below the yellowing on the edges of the leaves have just recently started. Can anyone please give me advice as to what might be causing this? I suspect it might be another ph problem but am worried that the white fly infestation might be the cause. I've only seen 2 or 3 whiteflies flying but any advice on what might be doing this would be appreciated. Pics below. Thank you...

Quick information on the grow I have 4 plants in a 2 by 3 grown with a 1000 W Mars hydro LED light and growing in a happy frog soil mix. I water twice a week usually every 3 to 4 days making sure they are dry but maybe I'm over watering???
