Blue dream tops of the buds issue identification

[WeedLover487]

I don’t do the whole EC and PPM testing either, but ph’ing on the other hand is a completely different story. Soil should have water ph’d between 6.5-7, whether you add anything to the water or not. My tap water is 7 out the faucet, but 6.5 is the happy medium because this is where most of the elements are available for the plant to use. ( This is however not the case when growing hydroponically or in coco ). Adding anything to your water will drop the ph and cause an imbalance in the nutrients availability unless you bring it back up. Otherwise you run the risk of feeding a plant that can eat it. Not sure how everyone where you live gets away with it, curious to see their harvest. If you’re using soil with nutrients in it, and your tap ph is 7, and you don’t do anything but water only, that’s manageable.

Yes, our tap water after adding nutes are usually 6.8+-.
So its good for most ppl with the strong strains. But sometimes there are gentle strains...
Ph I always check and adjust.

I think I know what the OP was saying. If you look online so much stuff say's you don't need to pH the water if grown in soil as it buffers it. While this may work out for some it isn't a one size fits all. I don't test ppm's but I do have meter to check if a problem arises my tap water is 7.6 out the tap and has caused me problems before so I have to pH down wether I use plain water or with nutes added. So basically some people are lucky to have perfect tap water some are not.

Yes, true. depend on the local water.

Sounds good.

I do not check or adjust water PH as a soil grower who uses mostly top dressing vs bottles. There are some excellent soil growers on RIU who do adjust water PH.

There are a lot of posts on this thread that I do not agree with so I can see how it is hard for you to know who to listen to.
Listen to xthso, he knows what he is talking about.

All I can say is someone who uses bottled nutrients should know the E/C of what they added to avoid over feeding.
If we knew the EC you were feeding it would tell us a lot. We might easily be able to tell you if you over fed or under fed your plant if you had that information.

I'm going to move on. Good Luck!

I grew a Blue Dream recently. I made a ton of mistakes and had a few issues so it did not turn out good. I took clones and have them in veg now, they should turn out better this grow. The purpling is normal for a blue dream.
Happy Growing!

Good point, EC to help identifying an issue is important too.
I will read about it and get me a meter.

Thanks!

Really? I am heating the room when it goes below 19C.
Didn't know that



No chance, the lights are 50 cm away and the temperature is not going over 28 even in the hot days.

I didn't mean your plant. I meant the Blue Dream example pic that was just green.

I pH in soil even though many say it's not necessary. I trust me over Dolomite Lime. But I don't pay a whole lot of attention to ppm or EC. I just go by leaf color & leaf reaction to tell me what the plant wants. All those feeding schedules that say add this or that at week 2 & increase week 3 get you in trouble sometimes. All strains are not the same & require different things at different times. Therefore, leaf color, curl up or down, droopy, burnt tips, dark spots, etc. tell me what to do.

 

[maranibbana]

what brand of soil are they in and how long have they been in it?

That is totally fine in your situation as you state you can read the plant.
It doesn't help the OP because he has not learned to read the plant yet.

My 1st impression looking at the second picture in the 1st post is that of a plant that was over fed something. Some posted they think it's a deficiency, maybe it is.
We would know if it was over fed if the OP used an EC meter. Without one growers in his area learn by trial and error and that is fine.

I'll bet many growers on RIU who learned to use an EC meter at some point in time have added bottled nutes to water and tested it with an EC meter and said Holy Shit! It's reading 2500 ppms and they cut it with more water because they know feeding 2500 ppms would be bad instead of blindly feeding it to the plants.

It's just a tool to make things easier. Trial and error works too, just might take a few more grows or an extra year or two to dial things in.

I also used ppm meters at 1st. But then I had 4 ppm meters & checked the same nute mix & they all had different readings. Some 150 ppm difference. Granted they were cheapos & not Blue Lab. I don't see many new growers with Blue Labs so the ppm pen thing is pretty inaccurate.
That's why I learned to read the leaves. Blue Labs are about $150 & up at my Hydro Store. Kind of expensive for what it does.

organics/living soils are a lil different and don't require PH adjustment to the water, and often zero dolomite lime. my current living soil set up doesn't have any dolomite in it actually.

and I never PH the water

Ready soil from the garden store, i added humus

I go an EC meter. I will write down in a new comment with updates.

update:


I got myself an EC meter.
I also got bio nova pk (0:13:14)
Tap water read - 250
With nutrition (Big bud, Pk, Cal mag) 1250 PPM

I tested soil EC (put soil 24 hours in pure water (1:1 ration), then filtered and tested)
The Blue dream - 915 ppm
The CBD - 605

But surprise! the CBD leaves started to get the same color, and they are a bit curling up.
There is now way that its heat or cold, so can it be that its light stress?

This is a 2X2 tent, with 2 quantum lights 120 each.
So 240W can be too much?
This is first grow with 2 lights, I got the second one when started flowering.

I turned off one of the lights..only 120W for now...
What do you say guys?


Current view



The blude dream on the left, still same color 3 days after feeding


the CBD from the right side starting too with the same color + curling leaves, but started only now? so how it can be light stress?



CBD another shot, curling and getting color

Do you give them 1250 every watering or once a week?

 

[WeedLover487]

Once a week, and its the first time I gave PK 13-14.
I am very careful with feeding. I gave less than the recommended dosage.
Now I will be able to feed better, with the EC meter.
I am pretty sure its not over feeding.

Maybe light stress?
I just notice the curling of the CBD plant, but I can see that it was also before...
It can't be heat stress.. so light stress? really?

I hope that 240W of quantum boards for this tent is not too much...
The lights are very high, 50 cm from plant.

It seems the two fertilizers you used are synthetic.
I can't find the ingredients for the bio nova PK.

The low soil ppm level if tested correctly can give an indication of soil fertility. A factor that would keep soil fertility up is to feed the soil not the roots.
Synthetic fertilizers do not feed the microbes in the soil it feeds the roots directly. If you have not fed any organic foods to the soil the fertility will drop over time and it becomes more like a coco grow if that makes sense by using synthetic ferts but those fertilizers would work better if balanced with other nutrients like nitrogen. Something like the general hydroponics trio of bottles would deliver a more balanced feed depending on the stage of growth.

So if you are not familiar with the difference between synthetic and organic feeding it would be wise to read up on it.

1250 ppms are a lot especially being that most of those ppms are P and K.

 

[WeedLover487]

I didn't get it...
What does it matter now if its organic or not?

1250 is not every feeding, and I read that its ok up to 1500 during my flower stage, and the soil ppm I tested is 915 ppm and 605.. so as I read about it its ok?

I got lost... you think its too much nutrition?
I fed with the bio nova PK only one time, low dosage.
I got it cause ppl said I am missing K values from my NPK ratio...

Forget that confusing post. Let me back up and ask you another question.

What have you fed the soil that is not a synthetic fertilizer during the grow?

If you do not understand this question then I would suggest learning what foods feed the soil (organic) and what foods feed the roots (synthetic).

Everywhere you look for flowering recommended ppm

What are the best pH and PPM Levels for Growing Marijuana?

Becoming professional growers cannot ignore pH. Maintaining steady pH and PPM levels is crucial to a successful grow.

Only synthetic fertilizers. There is also 15% humus in the soil.


Cal mag extra NPK 4-0-0

Bio Nova soil super mix - NPK 7-3-6
Amazon.com : Bio Nova BNSSM5L Soil SuperMix Liquid Fertilizer, 5 Liters : Garden & Outdoor

Big Bud - NPK 0-1-3
https://www.amazon.com/Advanced-Nutrients-Liquid-Fertilizer-1-Liter/dp/B001GBOAQC/ref=sr_1_1?dchild=1&keywords=Advanced+Nutrients+Big+Bud&qid=1588160569&sr=8-1&th=1

I added only now (by mistake) Bio nova PK 13-14 (0-13-14) instead of the soil super mix.

Cal mag + Big Bud + PK - All of them in one feed gave me with tap water 1250 EC.

So I don't see any problem with too much nutrition.

I think its a light stress. not heat, light.
I turned off one of the leds, and now I am with 120W.

I will update.

 

[ComfortCreator]

Thank you guys.

Untill now I got the answers:

No issue, genetics.
Low ph issue (previous post)
Cold temp.
Too much nutes (too much PK values)
Not enough nutes (starving)


All from well known members...
What a noob like me can do with all those great answers, that contradict each other...

What you do is read enough or ask around who really knows their stuff.

All opinions are not equal.

One poster in here is a pro, with years of experience in many mediums. Not me.

Being able to identify those folks is how to differentiate knowledge from guesses. As you say completely conflicting responses shows some are wrong, and few have enough info to know whats wrong.

I would never call anybody out directly, but feel free to PM me and I can tell you who to go to for the right answers.

The smartest and best growers do not argue. They know and sometimes discuss, but don't argue.

Usually you calculate 30 - 50 watts per sq. foot of coverage area. In 4 sq. ft. you need 120 - 200 watts.

Do any of you guys use Mega Crop ? It's the cheapest & easiest nute out there that gives amazing results. 1 bag of powdered nutrient & nothing else needed through the entire grow. Just up the grams per gal.
