re: Another Brix In The Wall - Sweet Pink Stink & Girl Scout
Could that be the cause of my symptoms? What's odd is that the environment has not changed and the plant looked great one week ago.
Symptoms
Almost every problem is an environmental problem, especially in a High Brix grow.
If it is too dry, stomata close and the plant begins to stress, using up lots of potassium in the process. Because the plant isn't respiring and the metabolism is low, Pretending it's a deficiency and trying to play catch up with salts won't work. , The leaves won't like a foliar feed much either as the stomata close in hot, dry conditions.
Once they close for the long term, you see symptoms in 48 hours, with necrosis in a week. Pretty much on your timetable it seems.
MJ likes a fairly mild climate and requires a good deal of humidity with higher temps if it is to grow right.
Here's a fix: Keep temps down, and rH at about 50% for 4 days or until new growth looks vibrant and no more necrosis is occuring. Cut off all the ugly leaves. Give a rescue drench and then raise humidity to 60% and then go ahead and let the temps get up to 80. That should help it finish strong.
I haven't said it in a while, but I've said it literally hundreds of times:
Nothing is more important than the environment! That includes The Kit, and everything else. Environment is the number one concern.
Congrats, they are girls!
