Lupins are dying

I should have a picture, but non available at the moment. From this description can anyone give me an answer. My plug Lupins are now 4 - 6 inches tall, with one or two larger mature leaves (the typically shaped Lupin leaf) and some smaller leaves that are not fully grown. The larger leaves are beginning to keel over, dying in fact, and eventually the plants look like they are rotting off. Can you over water Lupins? I thought they were thirsty plants. Any tips would be helpful, thanks.
If all else fails I would sacrifice one and pull it up to see what the roots are like.
There are many diseases that attack Lupins and one big problem is the Lupine Aphid which is a sap sucking insect,..so just think about the results of a sap sucking insects attack on your Lupins,..no sap then collapse,..worse is the Giant Lupin Aphid,..none of this is being helpful to folks with the collapse problem,..so its down to a spray of sorts.
21st of April,..on the left behind the tall pot,..there are 12 Lupin.
Mine on April 29th.
As of today,..starting to bloom.
I have grown Lupins for quite a few years no problems with seedlings,..or cuttings from any diseases or Aphids because i use Neem Oil,..its Organic,..will not harm Butterflies or Bees or anything that does not eat foliage,..Lacewings or Lady Bugs,..Pets or Humans,..i begin spraying at the start of Spring so no Slugs or Snails,..i have lots of Bees to prove its not harmful plus 4 Hedgehogs.
Neem Oil is collected from the tree and cold pressed to extract the oil.
I spray inside the greenhouse as well.
1 Tablespoon of Neem Oil.
1 Tablespoon of Liquid Soap.
Add to 1 Litre of tepid water (tepid to disperse the oil )
Spray with a spray bottle,..in a cloud spray setting,..you can reduce the mix after a few weeks,..spray on a dull day of course.
One can get Neem Oil by way of Amazon if thinking of future plant protection.
