Ok so here are the facts
28 days in flowering, this plants has 19 colas. FloraNova Veg&Bloom/Karma/KoolBloom. My 250 HPS is 5" away from the plants and canopy temps are 25c-30c. Humidity goes from 40 in light to 60-70 at night.
Growing in soil less. My PH is close to 6.5(test tube ph tester)
After finally moving to 1100ppm full bloom nutes. Slow yellowing of fan leaves turned very rapid and is killing many of the lower fan leaves within 2-3 days. I flushed her on the next watering and noticed a slowdown of the yellowing, the plan is to add a little more N next feeding.
At first, two of the colas coming from the one node with most yellowing leaves developed some minor browning on the surface of the upper fan leaves. As of yesterday the edges of the highest leaves are turning orange/light brown as is the side of the bud. It doesn't rub off and is exclusively happening on these colas. All other colas are nice and green, no burning, or other signs except yellowing fan leaves below.
Can anyone chime in on what this might be and how I can stop it?
Thanks a lot
