New Grower New Grower Having Problems! Day 39

[Slater]

Hi guys. I introduced myself yesterday so maybe some of you remember me. Like I said yesterday, I’m so excited to be here!

Using FoxFarm trio at half strength along with calmag half strength, all with every feeding about every two to three days.

Soil is 50% organic soil, 20% coco, 15% perlite and 15% worm castings.

Using three 300w led panels. Two Viparspectra r300’s and one Bloomspect bs300. Growing in a 2x4x5’ tent with 4in in-line fan and carbon filter pulling fresh outside air in since it’s summer here.

Temps are kinda high around 82f degrees average and 55% humidity average.

Anyway, I need help. I’m in the process of growing three plants. One super hash auto and two nyc diesel autos. The grow has been very smooth up until now, and still is going good, for two plants at least!

My two nyc diesel plants are healthy. One of them showed nitrogen deficiency but was resolved within a couple days. Around that same time, my super hash plant started the same exact symptoms. But as the diesel plants symptoms subsided, super hash was getting worse.

Starting at the bottom, some leaves were turning yellow and dying, JUST LIKE it had nitrogen deficiency. So I upped the grow big from half strength to full strength for one feed and even did a grow big folliar spray. All leaving me with the same sick plant that keeps getting more sick. The yellowing is moving farther up and has taken about 12 leaves now.

Well I fed her this morning, and like I always do I checked on her at 1pm while on my lunch break. A big fan leaf that had just recently started yellowing is now showing some kind of brown spot in the middle of the leaf. It’s starting to make me second guess nitrogen deficiency. Noticing some very slight browning on some yellowing leaf edges also.

I really want to get this lady fixed up because otherwise she seems very healthy. White hairs looking nice. Any help at all is super appreciated. And if you need anymore info from me that I left it please let me know!

that looks like it could be magnesuim diff to me, a feed of Epsom salts would do the trick. Nothing major to worry about. I like to use Epsom salts in a folia spray, a couple days of spraying and its all sorted.

this is where you may have gone wrong. You amended the soil to much and thrown out it's buffering which in turn is locking out the mag. So chances are this is just a simple ph issue that can be easily sorted on each feed by make sure you ph to around 6.2 - 6.5. Thats the best range for soil, I found great results at 6.3.

Ph'ing for soil is generally not needed as the soil will buffer the water... but if you do you will see a difference, a little more vigor and a little more explosive growth. Don't under estimate the power of ph'd water.

15% worm castings

may i ask what brand of worm castings are you using?

@Tim Miller scrap that last Ph figure I gave you just read your other post... try dropping to 5.8-6.0 and see if that helps

the good thing is its only the one plant effected,and its the different plant.my thoughts are that its just a sensitive plant,could be a combination of a few things overwater/smidge high ph too much N not enough of something else.
at least you nave pen and know ph of the in part,half way there.
dont flush just back off the nutes and watering a touch and keep posting.
get us pics of all 3 maybe someone can see something the rest of us cant.
keep er lit.

That's solid advice right there. Definitely a safe way to help assess the situation and get the the end of the grow. It's so difficult assessing if you don't know exactly everything that has happened up until that point. The. You can sometimes backtrack and find out where things went wrong.

That was kind of my thinking as well man. He is essentially running a hydro medium of sorts.

2 outa 3 aint bad eh ? you cant be doing anything majorly wrong or all 3 would be the same,thats another positive.
Med and Slater much better growers than i,and i did say in my first post dont take my advice get a forth opinion.
just to throw something out there,isnt coco very cal/mag thirsty ? as in some folk pre charge coco,and a flush is never a flush just a weak mix.

Ok so I’m gonna order a soil ph tester tonight. Are all those cheaper ones on eBay and Amazon the same? They all look the same, those triple soil, moisture and light testers? Which do you recommend?

And to who asked about the worm castings? I unfortunately got them at Walmart for $10 for 20lbs. Was this a mistake?

And also gonna post up some pics of the other plants like someone requested. The last two pics are solely of the other two ladies. Let me know what you see!

Hey bud, I think ph testers you get what you pay for i have heard good things about the accurate 8 for in pot ph. I could be wrong but I would hate to see you waste your hard earned on something cheap and nasty. I have a cheap eBay one like the one you're talking about and it's shit, I would buy the best you can afford

Ok then we’ll it looks like I’m putting in some research tonight on a soil ph tester. I’ll be honest, we don’t have a lot of money, one reason why I’m growing my own! But I want to continue to grow for years to come, so I DO NOT want junk. Thanks for the advice bro!
