So I made a mistake. I used cheap salt based fertilizer for my plants. It caused 3 of the plants to have some issues around PH and nutrient burn. One plant the PH was 5.8, it's leaves began curling upward and showing signs of zinc deficiency. It's leaves were becoming darker and thin. Two other plants showed a PH of 6.1 and had standard nutrient burn characteristics, tips of leaves curling down and yellowing, and yellowing spreading from the tips further into the fan leaves. I used the same nutrients in previous years, but this is the first grow I have done in a greenhouse. My thought is they worked well outside because the natural rains flushed most of the cheap and salty food out before they can cause damage. Live and learn.
I gave each plant a thorough flush, I kept soaking and letting them drain until the water came out clear. I let them recover from the flush and fed them some better nutrients from a local grow store. I balanced the PH to 6.7 PH in the nutrient solution. After the feeding and PH balancing, I managed to bump the PH's up by 0.3. All new growth looks very healthy and green and the plant with the 5.8 PH has even started to uncurl it's leaves. Once the dry out a little bit Ill continue watering with a PH of around 6.7, I want to have each plant at 6.5 PH.
I tied them down for the fourth time in LST. The branches in the earlier part of the plant are starting to grow vertically, like new tops. I topped each vertical branch, to help stimulate the main stem growth and to get two heads on each new branch top. The trick is to try and keep the branches around the same height by topping and or tying them down. In previous years, when I did not do this, the plant eventually picked a "new top" and focused it's energy on it[/ATTACH]

It's close to 45" in diameter so it's time to climb. ACDC from seed in early May.
