Sour Livers - RDWC - LED

Day 8 Am trying all four lights (4 x 240W) on a 20/4 schedule but may have to go back to 2 x 240W depending on temperatures. With all four lights on, the temperature is 27/28C and in the four hour dark period it is 24C. Day 9 This Sour Livers grow is going very badly! I have had to remove a second dud seedling (see pic). It stalled after showing the second set of leaves and did nothing for 48 hours while all the other plants pushed ahead. Had to go. Out of 5 original Sour Livers seeds bought from the Mephisto web-store only one has become a viable plant. From 6 Chemdogging seeds I got 6 viable plants. From 2 Fantasmo Express seeds I got 2 viable plants. I am a huge Mephisto fan but there is no doubt I have received a dodgy batch of Sour Livers seeds. I noticed from the beginning they were very small and one was almost white. Shit happens and although disappointing, at least I have all 9 pots in my tent filled with healthy plants. Day 11 No problems. Day 12 Have added Hydroguard to my nutrient mix after hearing good things on the Autoflower Network. Day 14 Not much to do except monitor temperature, pH and CF. Plant is very healthy. Have maybe detected a mutation - main step has split into two braches, More later
