I have already finished one grow, I’m on my second now, but I’m already thinking of my third because I’m doing photos next, any ways , I’m using ocean floor on the bottom and happy frog on the top half of a 5 ga fabric pot. I’m using 2 mars hydro tsw2000’s, it’s 3 auto flowers , black berry, Girl Scout cookies, and Pineapple express , I’m like in week 4 of flower. I always seem to get the same problems around this time. Leaves curling down, yellowish leaves. Mostly on the blackberry, the other stained don’t seem to do as bad. I stay in range on ph, usually 6.3. Temp is 81 degrees, and humidity is 38%, I give them about a half a jug of water every 3 or 4 days. I’ve only feed like 3 times, and cal mag like 2 or three, any advice would be greatly appreciated!!! And also wondering why the stems turn purple???






You don't have those all the way up in intensity do you?
Hi,
She looks hungry to me. Your leaves look like they are starting to fade which would mean your buds are looking for food and taking it from the leaves. That could also explain the purple stems.
Your temperature and humidity seem a little off which may be contributing to the problem. With a temperature in the 80s your humidity should be around 50% or higher. If you can, try and get your temperature down or your humidity up.
Nice looking buds! How many weeks to harvest do you think?
