I would def. get more lights. Your not going to like the outcome... using 40watts total of lighting.
Secondly, your using a freaking desktop lamp for light?? That's a no no.
I would suggest READING before attempting to grow Cannabis.. and at least know the basics before you try growing.
IMO, you just waste those seeds.. I mean yeah sure.. they're growing now. But, your yields are going to be shit. period.
You just don't have enough lumens.. especially when you switch them to flowering.. using 40watts of (Unknown type of bulbs) you'll
be really lucky to maybe yield 3 or 4 grams. Maybe 1 or 2 grams after you have dried the buds...
So, again.. I would just start over buddy.
Better luck next time??...?
peace.
