My seedlings seem to keep failing at the same point in growth out of 3 tries now.
Right when the second set of true leaves starts to emerge all hell breaks loose. This time around there was some slight discoloration, then I put a dome over it to up the humidity since it stays 16% in the house, or so my gauge says. Then the browning got worse, and the new growth started showing brown. The first pic is at day 9 from sprout, and the 2nd is today and the 3rd is from about 10 min ago. Its going downhill fast.
Conditions:
-Scotts Premium Topsoil (has peat in it and is pretty loose so i didnt add
perlite)
-Fan blowing on it constantly
-about 12 1/4" holes in bottom of cup for drainage
-Temps flux between 73-82
-dont know the humidity inside the dome, but droplets formed on the inside of the cup so it had to be high(wish i was:( )
I have since takin it out of the dome since the soil is still soaked from being flushed with 6.9 phed water(3xpot size) and put it in the actual grow cab. Humidifier is going off for 30 min every 2 hours and the exhaust fan is blowing constantly.
Ive looked and looked and can come up with nothing other than maybe overwatering but i thought that made the leaves droop, not turn brown.
I feel that 1 more false move and it will be done for.. again.
please help...
