alright while im no expert on growing im also no idiot either. i have done hours upon hours of research on this subject and come up empty handed. i apologize for the length of post just really want to give as much information as possible. hopefully the internets infinite wisdom can lend me a hand on this one
ive been having some bad luck recently with my flood drain system. started about a month ago when i was forced to pull 10 gsc due to a case of pythium caused by poor aeration in my reservoir. they had been growing fine up til this point and this is my NOT my problem, just wanted to give some background information. anyway i pulled the plants and washed everything with diluted bleach solution. pump, flood table, drain fittings, vinyl tubing, air stones and grow room walls. made sure it was all rinsed well and went over it all with 30% hydrogen peroxide sprayed from a bottle to make sure no pythium remained.
i should mention that while i used diluted bleach (1 part bleach to 10 water) on all my equipment i used 100% bleach on the grow room floor. i believe this is ultimately what is causing my problem
SO i acquired more seeds, hooked up all my cleaned equipment and started germination process again. about 15 seeds this time skunk #1. no problems germination 100% success rate. planted germed seeds in 1.5" rockwool cubes taproot down. 18/6 under a mars hydro 1200. within 2 or 3 days the first seeds broke surface and i suppose this is where the trouble begins. seedlings seem to have strong growth for the first 3 days to a week after which they started showing problems. starting with slight drooping/curling of the leaves downwards. as curling progresses the undersides of leaves start showing blotches of purple. as well as purpling of the stem which progresses upward into the veins of the leaves. a week or two after breaking surface seedlings are shriveled fallen over and dead.
its also worth mentioning that when i introduce the germed seeds in rockwool into the flood and drain tray there seems to be some sort of white granules building up on the top and sides of the rockwool cubes. very small white specks but lots of them. and when i tried flushing the cubes with water these granules remain a day later when the cube is dried out. my concern is that these are salt crystals and they are causing a nutrient lockup.
my concern at this point is that the 100% bleach solution i used on the groom floor is causing this problem. i research a little and learned that undiluted bleach leaves a toxic residue when it evaporates (sodium hypochlorite). assumed this what the white granules on my rockwool are comprised of and i start pulling my equipment apart again. cleaned everything again using just water, replaced my vinyl tubing with new stuff just in case, and wiped down the walls and floor.
SO i start a new batch of seedlings. afghani #1s 12 seeds. germ rate 100% again alluding to stong seeds/genetics. same process phed rockwool cubes into the flood and tray system. wouldnt you know it same problem occurs about a week in this time. slight curling followed by purple undersides of leaves and purple stems. 2 weeks after breaking ground seedling are shriveled and fallen over fucking dead again! the purpling and shriveling seemed to have a slower onset this time around. is it possible i have residual sodium somewhere in my system/room?
ive probably burnt hundreds of dollars on seeds alone not to mention electricity costs running intake and exhaust lights pump airstones humidifier. ive resolved not to start any more seeds til i can get a definitive answer on this issue.
ill include my specific information below for the sake of thoroughness. thanks everyone in advance
