Pls help me diagnose my problem, 5th week flowering

[Thundercat]

after I mix nutes it’s like 5.7 then I use the potassium ph up stuff

The one thing I noticed in all this was right here. It's important to add your ph up before you add your nutrients. When you add most ph up products to premixed nutrients it can cause precipitation of the calcium, causing a little white cloud in the nutrient mix or a second.

You can add ph down right to the mix at the end but not ph up it should go in first.

When I switch to different nutrients I will always mix a test gallon. I'll set the ppm where I want them and record how much nutrients that takes. Then I'll set the ph and see how much solution that takes. Then I throw that mix out, and fill my reservoir with the correct amounts in the correct order.

Thankfully my tap water is kinda high on ph so I rarely need to use it. By the time I add my current nutrients it's usually nearly perfect.

So just did a feeding with a feeding with a ph of 6.7 and the run off was 5.8.... I always added the ph up at the end after everything..

One thing, how will I know how much ph up to use before the nutes? I guess I’ll run a test and record how much I needed.. the thing is with these weird nutes, it changes the ph to around 5.8 no matter what the existing ph is and that is why I have to add it after.. it would be so perfect for hydro (what it’s made for) but says soil as well on the bottles.. it will literally change a ph of 4 to 5.8 and 7 to 5.8.. it doesn’t matter it always brings it too low for me.. and this is running it half strength.. have never gave them a full dose yet worried about burn..

now that I got run off of 5.8 I’m wondering if I should shock them with some like 7.5 water or something.. these nutes bring the soil ph down no matter how much ph up I use (potassium hydroxide). What would be my quickest fix besides buying new nutes or letting them go hungry when they are building the most flowers?

Thanks for all the help I truly appreciate it, this is my medicine and it’s finally legal to grow 4 of them so I want to try and fill my 4x8 tent next grow with just 4 plants trained to fill the entire 4x8 in most likely 10 or 15 gallon pots.. that should get me a decent yield! Haha.

Looks like too much fertilizer to me. Im also growing black cherry punch and it is fert sensitive. And Im running cobs 12" from my plant and not having any problems.

So, this is a question to some of you pro growers out there.. here is what I feed my ladies and I would love to come up with a custom blend for flowering so I’m not feeding as much nitrogen and veg nutes.. the thing is that the micro has some super good stuff in it for the flowering stage and it says to use all 3 bottles same amount out of each bottle during all stages of growth and I’m not sure how that works.. so far it’s alrifht besides the ph issue but I want to give them less nitrogen and more of the other stuff.. max I’ve given them is A little less then 3 ml/L and full strength is 4 ML/L it states.

All the ingredients and amounts are listed In the pics.. is are those amino acids in the micro food for the flowering stage and how are they helping?

Again thank you all and it’s a pleasure to be here. (I’ve been following these forums for the last 15 years or so since I was a little kid trying to grow a pot plant in my bedroom dresser with incandescent light bulbs, I legit knew absolutely nothing about growing and somehow stumbled on a street light 250 watt high pressure sodium light and I thought “this thing is bright as hell maybe it will grow plants alright?” unbeknownst to me it was the perfect light I could have got for my tiny grow area and found out years later.I grew one plant after another not really ever fully maturing them.. ( teenage boy with no weed on a Friday night? Oh there goes a premature bud ! lol

Peace and love.

You could attempt to run the Lucas formula with just the bloom and micro. I don't know the ratios you would need, but RIU or google search might. I used to run Lucas formula with GH products and it worked well. I imagine it could work with advanced also.

Try using some warm rain water by itself and let some water run off to clear out whats in there. Then next watering use 1 part micro to 2 parts bloom with a total amount per volume of water less than you have been using. And give your plants a break they don't need so much fertilizer unless you have some giant lamp and CO2 and everything else is perfect. You can use plain rainwater between feedings.

I got the opposite! Haha

Use low EC low TDS water at 80F, doesnt have to be rain water but rain water is really good stuff. Leave it in your grow area for a day to warm up.

 

[TheHarvester]

What's your run off EC/ppm??

Half strength every 3rd watering seems a bit low??

Also all that much potassium added to bring the Ph up might be causing an imbalance/salt burn when the medium dries out.
I'd ease up and water at 6.0 and have less potassium to imbalance the mix. 6.0/6.2 is a better spot to be at anyway.

I also wouldn't worry too much if they are growing nicely.

 

[jjess21]

I havnt got a ppm meter yet. I know I kmow.. soon enough haha.

I think I got the purple pheno, they are slowly turning purple.. weird how most of the hairs turned orange so quick into flowering.. should I be dropping the temps at night? And what temp is the absolute best for flowering at a low RH

 

[jjess21]

And I heard cold water has more oxygen in it? But you guys say warmer water is better. I will learn I will haha

 

[NirvanaMesa]

Mine turned purple also and all the hairs are red very early on also. I flipped the lights to flower on new years day. The flowers already look done but the crystals aren't done yet.

The warm water would be to rinse out your soil to kind of reset things. Room temperature water is good for watering with. Warmer water will disolve salts better.

You can let the night time temp in your room drop to low 60s to help with color.

Looks amazing bro, those leaves are loving whatever light you got them under haha

I think you got a little more of an indica pheno compared to me.. guy at oni seeds popped a bunch of them n ended up with what I got now p, terps are like nothing I habe ever smelled before.. I can’t quite put my nose on the smell.. like a cherry, tropical gas smell is the closest I can get lol. I flipped on Jan 9th. In the future I need more airy soil, I killed a plant trying to flush it n got root rot quick

I don't think you are supposed to adjust your water with PH up or down when you use the PH perfect system. I think it can actually cause BIG problems.

The run off is 5.8 because the PH perfect nutes drag the PH up or down into the proper hydroponic PH range. Although it seems low, cannabis plants can uptake these nutrients regardless of the PH being out of the proper zone because all the ingredients are chelated.

"In short, as long as your water falls between 4.5 and 8.5 pH (which is pretty much everyone’s water)-this technology adjusts your pH for you and keeps it buffered there throughout your plants’ growth and bloom phases!"

"When you use any Advanced Nutrient’s base nutrient, the pH Perfect® Technology inside automatically stabilizes and locks in your pH within the optimal range (called the ‘sweet spot’) of pH 5.5–6.3 – and keeps it there for one week."

Oh n my water is usually always room temp as I sit there n put the entire 40 litres of water through a brita filter.. yea that’s how much these bitches drink every couple days, 3 days max.. that’s with less than a litre of run off coming out.. so considering my kind of thick soil situation.. (should have used more aerous solutions like soilless or coco..) should I use more water than I usually would during the warm water flush or the same 40 litres I usually feed them but just ph’d straight water? Maybe with teaspoon of molasses? Apparently the beneficial microbes in soil like a higher ph like at least 6.4-6.7.. well the voodoo juice I use..

(advanced nutes voodoo juice is actually some of the most amazing liquid solution stuff in a bottle I have ever used.. you can literally skip a whole week or even 2 off veg with this stuff..

Anyone know how long black cherry punch will go? Or how done my buds are by just looking at them? I need to buy a loup or microscope

 

[NirvanaMesa]

I will let you know when mine finishes. Looks like it will be at least 60days of 12/12 maybe more.

 

[jjess21]

Think I’m at around 50 days or so I kinda lost count gotta check the books lol

Just at first look it looks pretty close honestly.
