THC Bomb Hydroponic grow

6/29 Water change this morning. trimmed more leaves. Everything looks great. Added Emerald Harvest, Emerald Goddess. 6/30 ph @ 6.2 probably from the water change. Ph down to 5.8. Trimmed a couple leaves. added 1/2 gal. water. added gorilla tent supports in my tent. makes a big difference. Much sturdier than before and i can hang stuff on them. 7/1 added some water 1/2 gal. trimmed a handful of leaves. opening my plant by pinning plant next to tent frame. 7/2 ph @ 5 added water and ph up to 5.7. Noticed leaf tips browning and leaves with slight curl, nutrient lock I think. Flushed control bucket with fresh nutrients. 7/4 HAPPY 4th! ph @ 5.2 this morning. ph up to 5.7💀 7/5 ph @ 5.6. no trimming or adding water. Noticed trichomes are starting to turn orange. This is my third grow. So far I have grown Blue Dream, Peyote Wifi and THC Bomb. Any suggestions for new strains? Thinking of growing Gorilla Auto or Girl Scout Cookies. Any advice greatly appreciated! Please feel free to like or comment. I always welcome feedback!
