Looks good man , ill be attempting my first mainline type grow with my new seedlings I've started today.
Someone else mentioned phospurus/potassium deficiency, IMO id say its nitrogen since nitrogen is being used to produce mass nodesites/stretching the first 3 weeks of flower .
Goodluck with the grow man
