Ok i watched both videos. I didnt see or they didnt say the application rate on the nourish-l. Can you take 1 gal and add the nourish -l at the highest application rate and add the photo plus one at 20ml mix well and then water into each plant equally tonight or tomorrow putting this on top even though you just feed is ok and then use these at the lowest strength application once a week.
I think that the photo plus one could be used at 5 ml per gallon. And the other whatever that says I'll guess and say 5ml per gal once a week also.
