PALMER PLANTS

strong growth from most plants. One of my berry medicals has shriveled up not sure if its due to too much light or too little water. Had an overwatering malfunction with my watering system so it took a few days of dirt aggitation to dry up. May have played a role in underwatering because i didnt want to keep putting water in it. Lowered the light to 18" for a few days, worried it stressed the berry out. Hopefully one of these fixed the problem. 6/10 berry medical #1 wilted too much first plant lost it sucks but it wasnt an autofem just a free seed so not all is lost. Plants are preferring the new white light i got puts out about 500 ppfd to the plants. Pots are very moist despite drainholes and less watering, just trying to keep the stem area moist and let the rest dry up. any advice would be helpful. Started noticing small brown tips, too much light? dialed it back to 18-6 now that i got a better light.
