Hello growing community, i am a first time grower and have been seeing some issues with my plants. These two photo period plants are 7 weeks sense sprout growing in Fox Farm Ocean Forest under a Mars Hydro LED. They have not been given any synthetic nutrients yet but o have started including CalMag in the last two watering. I have not seen any real growth over the last two weeks and the bottom leaves have been turning yellow as well. Please give any suggestions on how I can improve growth and help fix the yellowing issues.

Do you have a TDS tester to measure the PPM of the runoff? Also how does the runoff pH look?
Could be wind burn from fan my friend
They're looking good! It looks like it's time to start adding nutrients.
