help on identifying deficiency? mag?

So my opinion is 50/50 grow bloom and drop the tiger bloom... at half strength.

At this point measure the ph of the runoff. Ppm not as Important as mostly organic but still good info... just needs to be taken with a grain of salt.

I feel like a good flush with ph, temp adjusted light nutrient solution will benefit you but will also likely cause some u happy plants for a few days.

Have you flushed already and if so how?

Cal mag no more than 1/4 dose.

Your still showing a K deficiency and I still feel its a ratio issue but now not so much a root or salinity issue as the plants look to be improving and uptaking well.

Remember what your seeing is about a week old. So think back to the last 7-10 days and maybe there was something that's the cause you can remember and it may already be fixed. In this case maybe a flush is not needed.

But runoff number would be good as these nutes are what I call semi organic but highly available so some insight would be very helpful.

You did the right thing lowering light but still would be good to have a lux or par reference... not just to help you but also so you learn what works for you and can replicate it in future grows to dial them in

that’s what i was going to say!
yep the tiger bloom just doesn’t seem right. i think he stopped using it already on last feeding.. anyho..
thanks as i think the same though you write it so nicely.

Can I ask for your reasoning?

I ask because I'm in a similar situation as the Op.

here are the ratios for each he is using, ATTACH=full]1110875[/ATTACH]
i personally don’t like those ratio’s.. the stage he is at should be like 3-4-6 kinda thing..
so trying to get a good ratio for him
so maybe full on the two and half of tiger bloom?

Gammagoat · Apr 6, 2021

Thanks, GNick55.

Just trying to learn.

OP, which black gold product are you using?

Might be a silly statement this far along but the person using FF, um it’s fresh right and not expired? FF has shit for shelf life

Sorry...I've been misspeaking. It's "potters gold." Local guy in Grand Haven makes it and sells to a lot of the Michigan grow resellers.

So basically just do 50% strength on all the nutes?

I did do a flush last week, using the flushing agent + calmag from FF and watering until 10-20% runoff like usual. I raised the lights up a couple of inches and turned back to 100%. I was getting appox 950uMols at 85% at 12" away, according to the app. However, the app stopped working well and is telling me I need to plug in a diffusor. I wonder if my screen protector is influencing the reading.

Are all the plants showing a K def? I have a hard time reading the plants that were over watered, they havent looked well in a while. The "healthy" plant in front is also showing K def signs? Sorry - just trying to see what y'all are seeing.

I think we will be watering again Friday, I can get PH/ppm on the runoff. Thank you all.

First off, I know nothing.

But I wonder if soil is still retaining some of original nute load? Possibly affecting feedings?

I searched potters and thought this should be noted.

" Nutrient package includes alfalfa, crab, feather, fish, kelp, blood, and bone meals"

"In order to provide growers maximum control and flexibility, the incorporated nutrient package is designed to impart a steady release pattern and a plentiful, balanced nutrient supply to sustain healthy growth for approximately 4-6 weeks. Although accelerated culture will deplete sooner, some growers have reported near season-long release with minimized leachate programs. Supplementation with soluble, slow-release or additional organic fertilizers is discretionary and should be based on grower's experience and/or diagnostic interpretation of deficiency symptoms."

I agree with you - however these plants have been in their soil for approx 6-8 weeks already. (transplanted to final pots in veg.) I also think that the prepackaged nutrients is good for young veg plants for couple weeks, but not nearly enough nutrients for more mature plants. I am going to switch to FF soil once I run out of Potters Gold.

Imo use 50/50 grow and bloom only at half the recommended dose. Drop the tiger bloom all together

hey what’s up??

kyLman · Apr 8, 2021

Sup guys, looking for someone to ease my anxiety on this (smoking doobs inst helping yet lol). heres some pics for update, they are light as a feather and wanting water. I think they are all showing deficient. I am wondering if cutting the food in half is still the right idea? PH is correct, environment is ok (been 82/45% day and 72/56% at night..) I am not trying to be argumentative, just not understanding right now. We are on day 33 from flip

Thank you farmers!!

hey it’s not argumentative,
your concerned!
what are your ph readings, something is kinda locking out “k”..
no to full nutes it won’t help..

In the overwatered plants I can see it being locked out from the overwater two weeks ago. But the healthy plant in front is low in K, I presume from under feeding? it didnt have the stress the other two did ( plants in back of tent.)

So I am out of distilled water, I cant do a slurry PH test until I go get more. However I do have a shitty soil tester thing I used outside before. Is there another way to test PH of soil?

well when they need watering feed- the exact same as last time.
your ph thingy, mmm don’t trust it, it’s probably off abit..
someone may have ideas for ya.. you should take the exact canopy picture everyday too, for us..

Im just really on the fence, I feel like all the plants are hungry. Theres still 4-5 weeks to go. They were given water only a few times when we were trying to recover still a few weeks back..

giving more doesn’t fix it, it’s getting the right ratio or the ph needed at the time..
have you seen the ph graph?
if anything i’d go full on the two and only half of tiger.
