The blasting thing with tigrinum seems to be an enigma. Wet/dry, pot water only/ winter water restriction......Some seem to blast continually regardless of temp/watering until they get to be a large clump.
In the wild they bloom May - July when a massive monsoon kicks in in June. So the do go through a cool/winter dry, but does that mean it effects a summer blooming?
For many the clump size makes more difference than seasonal watering/cooling cycles.
I've been nursing along some seedlings I purchased in 2003. They been up to 6 or more growths and back down to 1, and then back up. Same for root growth.
They've been blasting for the last 5 years. I put them in baskets about 2 years ago, and went to low K fert. Leaf and root growth has never been better. One doubled the number of growths in the basket in just the last 6 months. It has a couple of sheaths going since late July. I started checking substrate conductivity and found quite a bit of fertilizer buildup so I started flushing (it takes a lot too!). The growth rate of the leaves, sheaths, and roots has accelerated in just a very short time since dropping down the substrate EC. So we'll see if this season will be different.
Lots of the blasting I think can be attributed to excess K in the plants and potting mix. Large multigrowth plants can suck up more feed than single plants so the "large clump" factor may reinforce this.
Check the EC of your pot and consider a big flushing. Try cutting feeding way down and see what happens.
