Question about PH and flushing

[Bambu]

Hey guys I have to ask to be sure. Seems like a dumb question but do I have to PH my water during the last 2 weeks of flush? I say no because nute uptake is not needed, but I really do not know for sure. Other than nutrient uptake, does the PH of the water matter?

Yes, you need to adjust your PH.

Also, you need to continue to give them nutrients until you harvest them. Unless, your goal is to force a deficiency.

Thank you, I always thought that was the natural order of things, to have the plant sort of eat itself down the stretch. I feel like if i dont see some yellow I am gonna be tasting the chlorophyl. So if the goal IS to create a deficiency during the flush(or if flushing is preferred) safe to say the PH doesnt matter during that flush period?

yeah flushing bro science says ph doesn't matter

What does that mean? I am asking not trying to teach here.

Sorry yea that was a little sarcastic haha. But flushing is bro science depending on who you ask lol. But when people do flush they just give plain un-ph'ed water. What we're saying is you get more out of your plants if you keep feeding until you harvest. Eating themselves is good if you're looking to bring out diff colors or get instagram pictures. Then again some are naturally genetically gifted to fade no matter what.

Thanks. I always thought those colors were good. So are you saying forget the colors and the plant should look healthy and green on harvest day? And taste would be the same?

Proper dry and cure is of real impact to the terps, flavinoids and chemical compounds.

I’d ph no matter what flushing may or may not be beneficial depending on your feed through the grow. If you feed adequately imo you have no need to flush. But like anytime you over feed a flush will be beneficial to prevent a toxicity. Simply lowering the nutrient concentration to the plants needs is usually all you need to do. But creating a deficiency i dont feel would be of benefit.

just my opinion

Thanks for chiming in @Aqua Man (: you da man

To get color to pop lower N as most do and then drop temps in the last week or 2. Temp is a huge influence in this area… that and genetics.

anthocyanin production is is increased/preserved when temps are low and photosynthetic rates are lower.… which happens naturally near the end of life of the plants.

Thanks Aqua that makes sense. Other than the leaf tips is there a way to know if you over fed?

Thanks so much, I will try that!

Well in term of nitrogen you will see clawing tips. Then tip burn but the first sign is usually dark green and shiny leaves. The dark green almost blueish is sometimes confused with an early P deficiency bit combined with the shiny appearance means N

Thanks but I really meant just in general, or is that the standard marker(N) to be able to tell if I over fed?

Yeah generally we feed the ratios we want and base the concentration off the response to nitrogen. Its a very complex topic when you get into the ratios but generally speaking you can have a high N ratio with a low availability due to nutrient ratios and how they influence eachother. Or a low N with high availability. So its not something you want to do by an individual ppm of nitrogen but rather how the plant reaponds.

eg Athena nutrients can be run at like 3.0 EC mega crop at like 1.6 its just easier to go by plants and establish a baseline for your type of grow, environment and nutrients then you can make use of those number in the future.

Basically somewhere between 100-200ppm of nitrogen will be ideal depending on the ratios of your nutrients so as you can see thats a huge difference

I really appreciate your time, thanks so much I am learning alot.

If you are in soil you should not be flushing anyway. pH is always important.
Natural fade will change the plant to yellow or other colors about a week or so before it's ready for harvest depending on how and what you grow.

Thanks I feel better about having some yellow in there before the chop. I am always open to suggestion. Using fox farm line at half strength, every other watering. Regular waterings I use neem cake and cal mag. FC-8000 light in a 5 X5 grow box. Godfather OG. 6 plants in 7 gallon pots. I am using half coco loco and half FFOF. Having great results I think.... but I know there is always room to improve. Gonna feed to the finish this time and see what happens.

If you get good plants with Fox Farms, then keep using it, but they changed the formula and we changed to LUSH instead and we get better results in our organic grow.

I will try it I love to experiment, thank you!
