Autos will not utilize FULL photo type feeding , start with 1/2 strength then go from there.
Feeding veg nutes thru first week of flower is recommended as it will still need nitrogen when going thruout stretch / branch out. Just know they are a bit sensitive to overwatering / overfeeding . They are plug and play , once started they won't stop til they are done.
As she goes thru stretch, you can begin to do some LST to her to OPEN her up for light.
They are on their OWN SCHEDULE so DO NOT GO BY BREEDER HARVEST ESTIMATE ..... Run them until they are done ( trich maturity) .... You will be surprised how much better they get if they are ripening longer.
Also , don't throw the kitchen sink at them ( too many products) they don't have the time to fully utilize ... Simple feeding works out better.
