is Ph adjustment in dwc really necessary?? i think not (PICS!!!)

hey guys just thought id share an opinion of mine.
im a noob to dwc and when first starting i was adjusting my ph everyday and ran into nothin but problems then i ran ou of ph down n my girl has just taken off from there on.take a look n tell me wot ya think. for sum reason they wont upload in order sorry

.

Give it time Its called ph deficiency for a reason. Look it up on google

Same thing happened to me my first soil grow. My ph was way off (high) and things were good for 3 weeks to a month in veg then one day almost over night they turned a sickly yellow and no matter how much N I gave them they just would not turn around. The plant had nutrient lockout and would not uptake any of the nutes I was feeding it. PH is very important and alot of people overlook that until it is too late. Now I check my soil and water/nute ph religously.
