@Coldkey Hi there mate Auto's Simply do not like stress.
Once their germinated they are on the clock so to speak and any strees or interference in their growing
Can set them back. This is why a lot of auto growers will not transplant or do any other stressful techniques
they usually do with photoperiod strains.
Just let the plant grow as it wants and as a rule of thumb they do not require the same strength of nutrients
as photo strains I hope this helps mate and good luck
