Yellowing and Brown Spots??

[Trippyness]

Hello mates.

I have yellowing and brown spots on my plants and now a couple are drooping.

Here are photos.

I keep PH at 6-6.8 depending.

Soil is Pro Mix potting no nuts in it.
Using GH flora series with Lucas.

use a guardian PH test.

Photos above.

I was underwatering so I now am watering fine and gave them a fresh amount oif Lucas formula 50% of full dosage yesterday.

I give them nutes once a week they are almost 4 weeks old from seed.

Also this is only there second dosage of nutes. Do they need to get used to it?


Any help appriciated. I assume they will bounce back since I just gave them fresh nutes and good PH.

Any help would be great.

If you were a female like in today's post you'd have 53 replays by now..I can't help the photo won't pop out..if there baby just water no nutes

 

[Po boy]

give her some fertilizer - go light with the nutes until she gets a little older.

I did yesterday.
Im at 50% should I got 1/4 nutes?

Do you know what deficiency I have?

Just gave them some ferts yesterday.

 

[Trippyness]

I have several ideas.

Also how long does it take for a plant to recover from a nute deficiency and turn back to green?

Is that fat green full of nutrients cotyledons i see? Im no expert but i think lucus was already a 3 part mix of nutes? I dont think it should even have any deficiencies without nutes as long as the ph is correct. I would say it probably has some type of early salt build up in the medium? Whats your ph in and out? Alot of people feed seedlings very lightly but these guys have been doing so with experience for some time. Usually once the deficiency hits the leaves hard it wont heal, the plant will eventually take the stored nutrients in that toxicity/deficient area and move it to new growth. You probably want to avoid that from happening eventually. Its all a learning process bro.

Lucas is a two part formula.
.
My PH is 6.0-6.5 usuiallly.
I just transplanted them last week into a new container and new soil so not sure how that would work.

I just gave them 50% nutes yesterday and hoping they recover.

I doubt its a salt buildup I be;lieve it was a def because I was underwatering and they were not getting much nutes.

Any opinions on what I should do or let them take in the nutrients and see how it goes?
I got 9 plants
Rogue Thunder
Purple Haze
Cotton Candy

Ph in and out? You mean runoff?

never checked the run off water PH but ill check to see what it is .

Just tested my soil PH is 5.8. I should up it to6.5

Yes, check the run off atleast to be sure the soil isnt too acidic or too alkali. Usually its fine but a run off lower then 5 can cause problems in most soils.
Did you transplant into a soil with nutes? Or just a bigger container? 50% feeding should have been more than enough to correct the problem. Watch your new growth,if it still has deficiencies check your soils runoff PH. Looks to be some type of phosphorus/calcium problem.

So you water it with ph6.5 and the runoff comes out at 5.8? Crushed Dolomitic lime will help your soil naturally have a higher ph when watering. Or just use ph up and get it to ph 7.0 run off should be much closer to 6.5. Also runoff will slowly change over time. Gotta keep an eye on it.

Hello, I just calibreated my PH pen and flushed my plants with 6.5 ph water.
Seems the run off is about 5.2-5.5 which isnt good. Means that my PH was off.
What can I do?
Need some advice on how to raise it as 6.5 water should have done it but seems my ph was lower than expected.

 

[Trippyness]

Question if I keep flushing the plants will this not over flood them and cause root rot and I dont want to do that.

I transplanted them to soil no nuts and a bigger pot.

A flush isnt going to do anything for your soil unless its salt build up from nutes! Try this, pour some of the same FRESH not used soil into an empty container, flush it and check PH. If its still 5.5 even though you didnt add anything then your soil will sit at 5.5 for a while, meaning the flush wont do nothing but potentially harm the roots. Buy/use a PH up solution for now, since your probably gonna need it down the line, most likely it will change PH when you start adding nutes.

 

[Trippyness]

I have PH up and down mate.

WIll ph up my sil once it drys as its quite wet currently.

 

[mainliner]

your ph in is 6.5

your ph out ( run off) is 5.5

to get your run off up to 6.8, you need to ph up your " in" to ...... 8.1

this will bring your runoff to 6.8

that's all you need to know trippy

You are a life saver will do mate thanks

 

[mainliner]

they got me under lock and key for a while lol.

it wont be long.


just stick to the plan trippy you'll have some nice mothers when we sort this out ..... But it looks like you got it undercontrol .


don't forget .... Ph up to 8.1
for runoff 6.8

the new growth will be green not the old stuff when fully recovered.....about a weekish.


gotta get back to the bat cave ..... Peace

Peace mate! Appriciate it. Will remember this hope your back soon

Quit worrying about pH run off. That will have you doing nothing but chasing your tail. Chronic underwatering will cause yellowing and brown spots. Nothing but water for now.
