Nute burn? deficiency? W/pictures

I have been reading and reading and belive it "was" bc of defincy. Would like to get some options.

Received the plant from a friend 3 weeks ago. Going to be a mother plant

Fox farm soil(25%) and coco coil(75%) mix

Under 4" t5 4 bulb

LSD strain

Using RO water

First week only watered once with cal-mag. No nutes at all. That is when everything started going down hill(she was extremely heathly when I got her). Tips of water leaves started getting Brown spots . Started with the larger lower leaves then worked it's way up. Freaked out and thought I did something wrong with the cal-mag and flushed at the end off week one. (Noob move I know) I also had a fan blowing directly on her throughout this week which I found out was not theright thing to do. Fan now above her between her and the light.

Week two I get liquid karma, silica blast, and pure blend pro (grow) as well as more cal-mag

Next water(waited till she was really thirsty before watering after the flush). 1.1ec 6.2ish ph with all nutes stated above. Leaves that had Brown spots all started to dry up and fall off and started to see yellowing with throughout older growth. Black spots on the tips of leaves continued to move to higher leaves.

Now to today. The beginning of 3rd week. Noticed that the roots were growing out the bottom of the small pot she was in so moved her to a 5g smart pot and watered her this time dropping the ec to 0.9 due to new soil coco mix and ph stayed the same at 6.2ish. Noticed tips of new growth areturning black as well and it seems like nuteburn but I am not sure.

your mix contains very little soil which means very little ferts in it. your feeding is too little for a plant this size. gradually increase the feeding to 1.8 ec with a high N/PK ratio and you should see improvement

Bit of a bad move transplanting her while she's still in distress. There is so much going on with her that it's hard to pinpoint the problem. Shouldn't be getting fed much if anything when going into a new pot using a rich soil like FF. A few roots showing up in the holes doesn't mean she's in need of immediate transplant.

She's acting like the pH is too high locking out multiple micro-nutients but exhibiting signs of excess P and K which would also lock out many micros. Things are really out of whack when both older and new leaves are being affected with different symptoms.

Now that it's in a bigger pot it'll be harder to flush really well and start from scratch which I hate to advise but if she doesn't come around after this new repotting it might be the only option. I never use coco as I had shit like happen when I tried it many years ago. But I never flushed the cheap stuff I got in a big brick so it might have been all the salt in it that screwed me up. Did the coco you used need flushing too maybe?



PS: Zem posted his message as I was finishing mine and that is another possibility but it doesn't look like simply a low nute problem to me.

Check out this decent nute problem chart I found recently.

Good luck with her!

oh yeah, i flush coco every time, i soak it in calcium nitrate 2g/L solution overnight, this precipitates the salt, then i flush flush flush, then flush some more, that is why, i don't like coco, it is for big scale ops who want a cheap medium. I assumed that he either had a good treated coco, or that he did that himself

I was told the fox farm ocean was very high in nutes and that is why I dropped the ppm/ec down to 430ppm (500 scale) .9 EC so I didn't burn her up bc of the nutes in the soil.

She looks so much better this week then last week. I thought she was going to die for sure last week. She was drying out in less then a day. She was in an extremely small pot 6"x6" square pot. When I pulled her out tonight her roots were all over each other. Couldnt even see the coco/soil. I'm going to get a digital PH reader Thursday. I'm using the drops in a small shaker right now which really sucks in my opinion. Hince the 6.2ish ph bc there is no way to know precisely. For a week she only got cal-mag then I totally flushed with only RO water bc i was under the impression of nute burn at first. Stupid mistake. Waited 3 days for her to dry out totally and wilt before watering her again again with low nutes .8 first water bumping her up to 1.1 during final water (2 days ago) before transplant.

I use foxfarm bushdoctor coco loco

Some cocoblends come pre-flushed like the ones ProMix makes. I use their HP, veg and herb blend and their potting soil blend. Feed them AN's 3 - part or use up leftover Sensi and Connie.

Just saw your post Levin. Maybe she'll be ok in her new digs. Takes a bit for them to come back. Hope you sawed off all those stringy roots when you repotted.

Off to bed.

That I did. She was really rooted up and twisted but they all looked heathly (no root roit at all, was worried about that as well) used clonex rooting compound as well during the transplant to ease her into the new soil coco mix. I'm sure she will love the new 5g pot. Can't wait to get a digital PH reader. It will ease my mind alot and this is week 2 of nutes so time will tell.

A digital pH meter......How do you meter your soil with a liquid meter properly? That's a pain in the ass.. you have to take equal measures of soil to distilled water (no less then 2 TBL each) and place that in a small jar and shake it for 30 seconds. Then let it settle for 30 min. NO SHORT CUTS! Then you can check the pH of the mix and be close to the soil's pH.

The thing is that soil's pH changes all the time.. You water it, it drops. As it dries back out, it raise's back to it's "rest" area.
pHing the run off is simply the pH of the run off and is no way near the soil pH!

A true quality soil pH meter is going to be only available through the use of professional equipment! The hot, top of the line unit right now is a Hanna that comes with the best probe available for around $400 bucks! Keep in mind that if you stick the probe in the soil (quality meter you buy and the probe you buy also). You need a probe and meter that will do the auto temp compensation needed for accuracy.

On the farm. I use Hanna - HI 99121 meters and probe combinations....I got them for $350 per on a multi unit deal and sold my old units to another farmer...these baby's meter down to the hundredth 0.01 !

Here's Hanna's pg on that meter:

Now get out your wallet if you "have to have it".....

BTW, I don't use it in my MM grows! I run organic, water only soil. No need to monitor pH!

If you add a good 1/2 to 2/3 cup of dolomite lime to FFOF.....that soil should be good to go too.
The thing will be your water pH and your solution pH......If it's high or low by a significant amount (keeping in mind that 1.0 point of pH is 100 times difference), you should then pH solutions to 6.5 in veg and 6.7 in bloom for soil growing, especially with synthetics.....My water runs about 6.8 and that's just fine. I don't pH my soils at all....

Bump.....

Ok, skip the coco and just use the soil next time...

Hi all please help with what you see.. it's got me confused I've tried all I know. I've had drooping. Wiltering. Yellow leafs. Light green leafs light and dark leafs. Plants look like their dying. Stunted growth and I'm growing in nft.

When using coco or Bush Dr. remember the coco does not have any nutrition. You need to use a good fert program almost like Hydro basically. It holds a LOT of water (which makes flushing harder) but the roots love it as long as you are dialed in. Worm Castings is a must when using coco to prevent nitrogen def. if you are going organic. Just my humble two cents...

I am allready in hydro. I'm using nft kits.

OMG shes dead. Start all over. I don't know how experienced you are but for beginners i recommend organic soil grows. They are much more forgiving. IDK i see one or two that can be saved but you better figure out where you dropped the ball PDQ.....Looks like you fried them with the nutes... you mixed too strong

I have been growing hydro for 8 years and never came across a problem like this. I am using weak nutrients at half strength. Like I say my ecs are 1.4. Which is ok. My ph is ok at 5.8. But the ph is rising and so is my ecs. I came in 1 day and a few of the plants were wiltering. The pump had packed in. So I got a new one and the plants picked them selfs up. Do you think I have a nutrient block. As they seem to be drinking as I have new growth but it seems like the plants are telling me all sorts of problems...

Their is 17 plants in total and 4 are effected it's really weird..

What are the temps in the rez? Some strains like a 6.3 range PH. Is the rez clean? If not use tap water. The chlorine keeps the rez nice and clean.

Yes I am using tap water. Always have. I am using ionics hydro grow nutrients. With some oxypluss. What would cause plants to droop and leafs to yellow? Or new growth to be really light green

The room temps at around 76 Fahrenheit
