Hi All!
i have a sick seedling as mentioned in the title, its had a rough time, due to my incompetence or a bum seed, i'm not sure. I germinated 4 other seeds of this strain & none popped except this. I've been experimenting a bit, as you'll see below, i've tried a few things & tbh i'm just trying to make sure i'm on the right path now.
i spoke to the guys who rep'd the seeds & they've been really good about it.
quick summarry, popped all of the plants in the pics in RO water, abt 12-24 hrs then to damp paper towel for +- another 24hrs. kept dark & at 26deg C & abt 65 % rel hum. other 2 plants in pics are an unknown sativa & an indica (judging by leaves - may be hybrids), sharing the same enviroment & loving life so far, started 2 weeks before the auto so i had plants to "practice" LST & HST on.
from day one its been slow, slow out the shell, slow to form a proper tap root, put into coco str8 from paper towel, PH'd 5.8 water with a small amount of Mg & Ca less than 100ppm. blah blah blah as below template.
(see the potatoes in the pots? testing for fungus gnats - caught a few flying around my plants, on sticky pads) have also had a very light spider mite problem, which (fingers crossed i've gotten rid of) i used 3 doses of pyrithrum via foliar spray, started 10ml/1l then 15 for the 2nd spray & 20ml for the 3rd over about 9 days - this may have made contact with the leaves of the seedling, i also used a foliar feed @ about a 1/4 mix which may have hit the seedling - i also used this to microdose the coco for the seeling (less than 2 ml every 3 days)
i gave it a 1st feed of 1/4 strength with a bit more calmag, then i flushed the medium about a week ago when i saw the first signs of nute burn, gave it about 4 days then gave it a light feeding with a bit more calmag & the new growth seems fine, but i'm still worried that it hasnt quite spread to the upper leaves yet.
i keep the lights between 10-15cm above the plants, its a closet grow & i dont really want to go splash out on a shit load of equipment until i decide if i want carry on with growing, so i dont have a huge amount of control over the enviro but specs below.
