Clones look healthy above the rapid rooter. I pulled a bit to see if there was resistance and there was none. Instead they all come out and were rigid, white, and hollow. There are a few tiny clear worms on the rapid rooters (fungus gnats?). Rooters were soaked in tap water (hard as shit). Clones were about 5 inches. In dome with hearing pad. 18/6 light cycle. Should I keep them? Did the worms do it?
The worms are not good, if you want you can keep them.
If you do keep them I recommend mosquito dunks to kill off the worms and I always recommend B1 Thiamine (Vitamin B1):
B1 is produced in the foliage of plants and transported down to the root system where it has an effect on root growth and development. In tissue culture and rooting preparations, B1 helps to stimulate the growth of roots on new plants but this is best used in combination with rooting hormones. B1 can assist at any time in a plant's life with root regeneration where the root system has been damaged or stressed through high salinity, pathogens such as pythium, nutrient deficiencies and toxicities, high fruit loading etc but only if the foliage of the plant is unable to produce sufficient supplies for this purpose. Use of B1 is seen as a 'back up' or 'insurance policy' as it is difficult to determine if a plant which has come under stress is capable of producing sufficient B1 to send down to the root system to assist in cell development. Use of Vitamin B1 in plants is the same as in humans - it is most useful where a deficiency exists for some reason. B1 is best applied as a seed soak to speed up germination (root growth), or as a foliar spray. B1 is an organic compound and as such is rapidly broken down by microbes in the nutrient solution (they love to eat carbon based compounds), adding high amounts of B1 may ensure sufficient thiamine stays in the nutrient for a few hours for some plant uptake, but generally microbes will break this down rapidly as well.
