just started noticing yellow Spitsbergen on my upper leaves, I’m giving them full strength Lucas formula, with 2 tsp cal mag and 1/2 tsp of beasty bloomz in tsp at 5.8. Anyone know?D44244BE-468D-4415-9C49-0B8D4808DE80.jpeg57EFCD3A-6C14-43AD-9299-CD313D58795C.jpegA75ACA23-0EB3-4793-BEFB-95A5F3693086.jpeg

What's your NPK??? What's the %
I'm going with potassium. You got purple, blue and yellow leaves going on. They look just slightly glaucous, and the yellowing is coming in.
Have you been letting your ph climb?????
If it isn't lockout, or slightly too much nitrogen. A pk booster wouldn't do any harm.
Do you have any idea of you ppms?

Have you lowered you nitrogen yet?

I’m using gh flora micro/bloom at 8/16 mL(Lucas formula) and it hasn’t changed since the start. 5.8-6.0 has been the only range I water in. I have only used these and the cal mag and fox farm boosters. No ppm meter yet, I did notice that my run off comes out at 5.3 but I’ve heard that measuring run off from coco isn’t the best to go by.

Lockouts your problem dude. Sorry.
I love my coco coir. It's my medium of choice.
You have to treat it exactly the same, as any DTW garden. That means matching your waste, to what's going in.
Potassium is your problem, because the low ph in your coir is locking it out.
You gotta let it get close to 6.5 in your media before you top off. Swing from 5.5, to 6.5 each feed. Meaning. Your feed is 5.5ph. On each first feed, it's good if the ph of the waste is just over 6.
You have to treat your coir, like a reservoir. You're topping off, and letting it swing all the time.

Check this chart out.
See where all you essential nutrients are sitting for flower?

Let your ph swing bro.
Swinging is healthy :hump:

Awesome info man, so I just watered like 30 mins before I posted the thread, what would you advise me to do? Flush, then feed with higher ph? And let it swing or how do I go about starting to fix the lock out?

It really ain't too bad dude.
I'd just leave it until tomorrow, or next feed. Then- give it a little flush.
Happy growing brother.
Much love

ya less is usually more with coco.. Id be careful with too much calmag. too much cal can cause some nasty problems. Before I started using MegaCrop I got best results adding epsom (gets you mg and S) with most feedings and then once a week or so using calmag instead of epsom.

I feel like a damn advertisement because I keep repeating it, but I haven't had so much as a single problem since switching to MegaCrop. I'm adding a tiny bit of booster this last half of flowering to see if theres any difference, but I was very happy with just using MegaCrop.

Good luck and Timmy been giving sum great advice!

I don't see how lockout or potassium can be viewed as the problem. What about that orange colored spotting? Why hasn't that been addressed? Tim1987, I've read your posts and you don't make much sense.
How about this? Stop the additives and just use the 3 part trio by itself, since that's what it was designed for, and see how that works. Also, the ppm and pH need to be known, particularly the ppm as that's the component that drives pH. The company website has better info than Tim does.

Did you read the ph of his runoff????? 5.3.
What do you think that's doing?
It doesn't make much sense to you, because you don't know what cations and anions are. Or how they form into ions that feed the plant.
If ions aren't being formed. Lockouts gonna happen. Isn't it!
Do some reading, it can help.
Plant nutrition is chemistry.

Agree with "less is more". That's the whole point of using the Lucus Formula.
And Beastie Bloom is quite concentrated at 0-50-30 from what I recall.
Its hard to tell from pics but to me it looks like build up which is causing issues with ph and micro uptake.

JMO, but those leaves don't appear to K def.

Between the coco and PK booster there's a shit load already in there

It looks like PK toxicity/burn. A common problem with Beastie Bloomz

OP, you really need a TDS meter. Knowing the PPMs and PH of whats going in will save you a ton of headaches.

I respect your opinion T :peace:

In my opinion it's potassium. Because it's in mid bloom, and needs a lot right now. As most of us know.
Npk are the most mobile macronutrients.
IMHO. This stage of flower. If it's a ph lockout, K would be one of the very first to show.
I think op's ph has to rise. Regardless of which it is.

I’ll definitely be looking into megacrop Next run, I’ve heard nothing but good things about it

That's the problem with your posts Tim. You give your opinion. ppm is the component that drive pH. How can you read that the OP is using so much fert and still feel good about potassium? Oh right, it's the cations and anions... and just your imagination. Bad info in these forums does nothing but mislead people. If you have to qualify your posts by saying it's your guess or your opinion, then don't bother typing.

My very first post.
"If it isn't lockout, or slightly too much nitrogen. A pk booster wouldn't do any harm."
OP has a ph issue. Which is locking out K.
That is what I believe. OP could have shit tonnes all ready. But at that ph, it isn't available.
Read all my posts properly.
My opinion is clearly stated. Stop putting words in my mouth.
He's in coco coir. It's dtw. Measuring waste is a must. His waste is ph5.3
