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
