To me, the plants seem to have a few things going on with them.
A couple things comes to mind to salvage the plants:
-Make sure the lights are not too close to the canopy. With highly stressed plants it's less detrimental to have the plant slightly under-illuminated rather than baking under the light.
-Ensure that environmental factors are in check.... Try to keep it under 84F and above 55F at all times. Monitor the relative humidity as well in the room. Since you're still in the seedling stage, you can run pretty high (55-70%) on humidity without much concern. Make sure to reduce the relative humidity a few weeks after flowering has been initiated. Make sure a fan is not blowing directly on the young plants, use indirect air circulation.
-Transplant the seedlings into a soil mix with 50/50 perlite. The perlite will help increase oxygen content in the rhizosphere, and result in new root growth. The plants need to focus on the improving the root system. If you take one thing away from my response, it should be that the root zone of those plants needs attention. I have never used B'Cuzz's root product, so i can't offer any experiential advice on that topic. I can say that there are a plethora of mycorrhizal innoculants on the market, and the top ones (without getting too deep into fungi/bacteria) are
Great White, OG BioWar, and
Xtreme Gardening. Note that these products are most efficient in mediums that are not saturated with synthetic fertilizers.
-Avoid using high nitrogen fertilizers on rooting plants, or plants that have just been replanted. Like all elements in a fertilizer, nutrient solutions with too much Nitrogen can really screw a young plant up.
In a nutshell i would do the following to attempt to get them on the right path:
-Ensure all environmental conditions are within specifications
-Step up the dosages on mycorrhizal innoculations
-Flush the medium with a product made to bond to salts. (EX: Florakleen,
Clearex, etc..)
-Begin fertilization again at 33% strength once medium has sufficiently dried from flushing
-Do not rush the growth of the plant. It is stressed and needs to grow roots before it will grow foliage. It might sit "dormant" for a week or two before growth becomes normal again, but the plant is growing new roots.
-After plant stabilizes and starts to grow again you might try supplementing with
General Organics Cal-Mag + to see if growth greens up a bit
-Make earthworm casting teas and apply bi-weekly
I hope any of this information is helpful to ya, Eska.
