So I’m roughly 6 weeks in from seed, couple weeks into flower. I had really high ppm at the start of the grow so I had flushed and the last few weeks my girls have been looking great. Now that I’m about 2-3 weeks into flower I’m starting to having some yellowing at the tips as well as random light streaks towards the veins. My last feed was yesterday with the typical feed as follows
1.25 ml AN micro
1.25ml AN bloom
1.25 ml bud candy
2.5 ml cal mag
2.5 ml liquid seaweed
2.5ml silica blast
Lights are on a 24/0 schedule as these are both autos. Water ph is around 7 going in and around 6.5 ish on runoff.
Not trying to sound condescending and I could be wrong here but - Im using the AN line you have and I have to say the feed measurements and mixture seem to be very off.
As i said i could be very wrong here tho, have you used these nutes before?
Appreciate the response and yes I have for quite a few grows the soil chart for the trio line says 4ml per gallon so I’ve been feeding roughly a quarter of that every other water as to not cause any burning, they seemed to do fine up until now but I’m not sure if it’s too much or too little, I thought typically the tips yellowing was a sign of burn but I’m not feeding hot as far as I’m aware.
When I flushed a few weeks ago it was around 500ppm on runoff, havent checked now that burning has started I didn’t want to over water plus waiting to see how it does after a day or so.
I just didn’t put it in the list I do feed the whole trio throughout the entire grow. I’m feeding the same amount as the others around 1.25 ml.
Also not sure on the ppm going in I did not check what it was last feed as everything was going great so I didn’t really have a thought about doing so.
When I started having deformities show up in veg I check and it was like 1600 something on runoff so I flushed down to 500 and it was going great after that. That was about 4 ish weeks ago.
And again I could absolutely be wrong but that with me feeding 1.25ml per gallon and in ffhf soil, to me that just seemed incredibly high.
You need to start measuring the feed PPM both intake and run off and documenting it.
Advanced nutrients is very easy to burn tips when you feed. Flushing is normally not necessary when using advanced nutrients unless you’re just trying to run off the pre-charge nutrients of your soil so you can start feeding yourself
For you, you should run off (and try to stay) at 1000 ppms each time you run off and feed accordingly.
There is a mathematical approach to this but it comes in time once you figure out what it takes to feed your plant to maintain that 1000 PPM runoff.
Everything gets calculated. The ppms of each of your nutrients the ppms of your water etc. this comes up to a total number of ppms that you feed your plant.
Now correct me if I’m wrong but the entire point of the ph perfect line is that it’s chelated and acts as a buffer (according to rep) making nutrient uptake available within the 4-8 ph range so that being said is do you believe ph could even be an issue?
Watering time should also be tomorrow for clean water so I will check it when I water and see what the runoff is.
Also should I be feeding the exact same of each the grow, micro and the bloom all through the grow regardless of veg/bloom?
@Theguapcrop you might find this thread helpful and it will save you and @Lostgirl a lot of typing lol. Skip to like post 100 onwards
There’s a feed chart someone posted towards the end and its a very good one. But i would add that i fed RELIGIOUSLY how Lostgirl told me, i didnt let go of her hand until i really got my footing with measurements, runoff etc.
Not necessarily. The pH perfect system is what’s called chelation. As long as you’re utilizing advanced nutrients pH perfect micro grow bloom ect it’s not actually adjusting the pH of your soil it’s actually chelating (adjusting the nutrient uptake) and I freely add plenty of nutrients that are not AN products without issue.
Example
If you’re using any type of nutrient and you know that your npk values our best reached at 6.5 so you pH your feeds to 6.5 all the time so you’re nutrients can become available to your plant through its roots…
With ph perfect the chelation makes the NPK available at lower to higher pH uptake. Your nutrients will become available to your plant at let’s say 5.0 to 9.0 ph. (This is the main reason I utilize advanced nutrients pH perfect)
It’s also very important to never pH your water while using the pH perfect system
