Yellow spotting. Nutrient burn?

[Mass117]

Plant is in 3.5 weeks of vegetation. Recently moved it up to a 2 gal pot and upped the level of nutri just by a very little bit (about 20% more). It looks like newer young leaves at the top has some slight nutrient burn. He larger leaves do have some yellow spotting on top and underneath. One leaf has a “claw”, while some of the medium sized leaves are like folding in/upward. It mostly looks ok to me but not completely perfect? I have been spaying ‘green cure’ to prevent any disease but the increase of the yellow spots do concern me. FYI I am a beginner But have followed the basics the very best I can. The strain is Sweet & Savory (90% indica). Seed expert said 60-63 days of flowering . Looking to start the flowering stage by at least the 5th week mark. Any thoughts or concerns on the current health and stage of this plant? It’s the only one I have. Anything helps! Thanks and god bless ✌️🇺🇸

Yes the burnt tips look like nute burn. As for the yellow spotting, I'm guessing it's from the foliar spray you are using. Are you spraying with lights on or off?

Usually lights on. I happen to get to doing it 1-2 hours before lights off. In the 18/6 light hour period
