plant problems maybe defficiency???

hello all i am starting off on my new grow. I am using sunshine no4 grow medium soil 1000w hps dimmable to 500w. Just recently i transplanted my plants(4 white widow and 1 acapulco gold) and put them into my grow room for the first time under 500w hps and noticed that my plants were acting up. the bulb in over 3 feet from the plants to avoid stress and heat for the first week. Plants look good and are growing but the older leaves are starting to brown and i dont know what this means. I added a dilluted composte tea brew for the transplant and some distilled water. They were under a t5 for a month an a half and went straight to hps. can anyone diagnose what this might be. i clipped some of the leaves off because they were getting bad. Should i even be clipping them off or not?. Thanks

oh and btw i am not using nutes for the first week so im not sure what it is. they are stillunder vegging cycle of 20/4. the newer leaves are getting a yellow tint to them also. the were doing awesome under t5. The nutes i will be using is fox forms trio grow big big bloom and tiger bloom along with root drench every 2 weeks

Were you foliar feeding/spraying the leaves?

No foliar feed or spray. Just the initial watering when transplanted.

What's the ingoing pH and the runoff pH?

I am not sure what my pH is I do not have a pH tester but I did not think I need to use one since I am using distilled water. In the picture they don't look as bad as they really are but you can only get a good idea of what they really look like. Could it be from the tea brew because I did brew for three days and diluted it with 2 gallons of distilled water with a total of 4 gallons of diluted Tea brew

Ok. I can relate to that but I didn't give any to my Acapulco gold and it is kind of having the same affect but not like the white widows. I had it at 750watts for the initial and thought it was too much and turned it down to 500 but I am using Mylar. Does that have an affect even though it's 4 feet from the plants?

Nobody else has any ideas??
