Hey T-Mater,
Personally I run drip stakes, they are pretty much wide open basket style emitter stakes. They do not create any back pressure. I do regular flushes every 4-5-6 days or so depending on how much
nutrient my plants are up-taking. (i.e. when the res. runs dry)
Two reasons for this are to prevent nutrient lockout on the plant roots themselves, and to keep my emitters or drip stakes clear.
Give your plants and flowers some time... they are going through a huge change in lighting and getting used to their new non-controlled climate.
