hi when should I stop feeding grow nutrient

Stop feeding grow nutrients at around 4 weeks , then use flower nutrients until week 9 ( two weeks before the end ) , 1 week of finishing nutrients and then flush with ph water for at least last week ( I do two sometimes )

Week 5 or 6 of flower I would stop using grow nutrients. After week 2 of flower I would start to slowly backing off grow nutrients. And yes there are many variables like pH, strain, nutrient brand etc... But u can get by with this for a 8 to 9 week flowering strain.

It is totally depending on your nutrient brand and your nutrient schedule. Generally speaking you don't stop giving grow nutrients but you give less during flowering until mid flowering. As you should know cannabis needs more Notrogen in vegetative stage and more PK in bloom so experienced grower are playing with the NPK amount more than the "grow" or "bloom" label ( which are just label to remember you that grow = more N and bloom = more PK ). To answer your question you can cut the grow nits right now after the 2 weeks of stretch but it is better to slowly decrease the grow amount than to cut it

Nice looking plant she looks picture perfect. Your definately in bloom. No need for the extra nitrogen. I usually give my autos a light flush starting end week 4/week 5 then switch them to bloom nutes. I do this and check my run off ph and ppm to make sure nothing has been building up in my pots for the past weeks. I typically flush until the ppms are under 900 ppms. This is my personal opinion. I rarely give more than half strength nutes during my auto grows but I have seen some growers with large plants handle a bit more nutes. I'm running 650-700 ppm nute solution in week 5-6 using a 0.50 scale TDS meter. Then usually max out in the 850-900 ppm range depending if they are feeding heavily during weeks 7 and 8. I'm actually going to be switching to Remo nutes on my next grow so I'll definately be following your diary. From my research they actually put more than just n-p-k in their nutes line. Hope this helps.👍

Hey my man, so you can stop using grow nutes at this point and start full bloom nutes. First week of flower I use half and half before cutting out grow nutes all together 2nd week. You're Growing autos so remember to start with half the recommended feeding and go from there depending on your plants response. It's always easier to recover from under feeding than over feeding. Let me know if you have any other questions. 🇨🇦🌴🙏👊
