No need to switch to 300 watts yet, I would let them grow under the 75 watts for the whole seedling stage (3 weeks), then when you up the light trasplant to at least to 1 gallon pot (4 liters), that will ensure that they have room to grow.
@Mrs_Larimar, I just recounted my weeks these are the star of the 6th week. 2 more to go on the GDP and about 3 or 4 on the glueberry. You can see the difference between an indica dominate pheno and sativa.
@Ganja79,wont give to much nitrogen in flower... let them fade^^or give them calcium and magnesium as single product without N
What i can see looks more like a Lightburn
@Mrs_Larimar, yes the GDP is so frosty. Glueberry not as much. I'm going to post some new pics please tell me what you think about leaf color. Starting to fade a lil should be just lack of nitro during flower. I just added bat guano last week.

There's nothing I love more than logging on and seeing a new grow starting. I get so excited to see how everything is going to develop as the grow progresses. I wish you the best of luck in this grow my friend.
Cheers
