Planty Dying, please help

Cherry Slyder

it was doing great up until a couple of weeks ago when I transplanted from a 1 gallon grow bag to a 3 gallon bag. Soil Mix is ProMix. I have not been feeding the plant very heavily at all. Every third feeding with Fox Farms grow big. 5ml per gallon.

I PH my water to 7. These symptoms started showing up 7-10 days ago and have worsened steadily since.

Yesterday I flushed the pot with 4 gallons of PH 7 water. This is what she looks like this morning.

Anyone know whats up? She was doing so great and this happened out of nowhere. None of my other plants are showing any signs.

A few things to note...the stems are deep purple and they weren't always this way. Phosphorous? I don't know but just an idea. I also think she might be over watered and I am trying to dry her out now.


Please if someone who knows what they are talking about can help that would be great. Pics will be up within 15 minutes. If anyone can help I would really prefer not to lose this girl. I've heard wonderful things about her smoke.

I would lower the ph a tad to around 5.5/6.0,make sure that the plant's have good drainage.Check the run off with a ph meter i would bet that the ph will be higher than 7.I would get hold of some sea weed extract or bat guarno anything realy that will give the plants that bit more nitrogean.When you are watering the plants wet them through but then leave them till the top 3 ince is realy dry this will help at the start but then you will know when the plants need feeding just by holding the pots.Too many people think that plants need water every day or other day but they don't one water a week if done right will do the plant's far more good.A plant needs plenty of water then it must be allowed to dry out this is how to get 100 % from what ever strain you are growing.By lettin a plant dry this will anable the plant to send out more new roots in search of water and nutrients.If the plant starts to dry at about day 5 then add just a tad of water.Also do what you are doing with the watering now but say once in every 4 feeds miss out the nutrients.This will allow the plant to utilise the nutrients that are left in the soil.If you don't miss a feed every so often then the feed strenth can become realy concentrated and this in it's self can cause the yellowing.Sorry about the book i have wrote for you but hope it helps...tyke...

Definitely ph problem causing magnesium deficiency. Just lower the ph a little.

I have cal mag suppliment, should I add some of that to my water?

My water is really hard. I had been using the cal mag a while back when using store bought water but have not been using it for my tap

First off your in ProMix, which has no NPK nutes to speak of (does have Cal/Mag via the Dolomite)

second your feeding FF GrowBig 6-4-4 every 3rd watering

You upcaned which spread your nutes out into the mix with no roots yet thus reducing the % of nutes available to the plant

While your PH might/could be off a bit (and you should check and adjust) the problem is more like the plant is starving

You should be feeding 1/4 to 1/2 strength nutes every watering!

 

[greenguy78]

what you are saying makes the most sense to me riddle.

this plant was great looking until i transplanted...that's when everything went south.

my next question is should i wait for the soil to dry out before watering with nutes or is this poor girl starving so much that I shouldn't wait for her to be thirsty to feed her?

I would flush her with cold water ph'd to low 6's and and have 1/2 strength nutes in the last gallon of water you use

read page 36 of my NooB Advice thread for the why

 

[greenguy78]

Thanks dude, appreciate your info and I will check your thread out.

Seeing as how I flushed yesterday do I need to flush again or should i just hit it with the nutes?

She is still super moist from the 4 gallon flush yesterday, but my PH in the flush wasn't exactly where you wanted it.

What is the ideal PH if my water? I thought I was shooting for 7. I'm sure that info is in your thread...thanks for help.

Just feed her if you have already flushed

and yes that thread has everything a new grower needs to know

 

[greenguy78]

Thanks dude, I'll get her some food. I hope it does the trick.

Refer to this, really useful. Make sure you're looking at the one that's for soil. Your Ph should stay in the low 6 range a small fluctuation allows optimal nutrient intake. Between 6-6.5 would be ideal. Good Luck

 

[greenguy78]

Thanks for the chart. That helps a lot.

It also helps explain to me why my plants have been exhibiting what always thought like phosphorous deficient.

My water is a 9PH out of the tap. That chart is most helpful. I'll start going to 6.0 and see what happens.

I will feed her tomorrow morning.

 

[Sealion]

Great, good luck and keep us posted

 

[greenguy78]

I re-configured my PH adjusting routine and now add 1ml of PH down into 1 gallon of water. This brings the PH to the preferable 6.0-6.5 range.

I fed with half strength this morning. I am optimistic we have found the root of a problem that has been haunting me since I began growing. I will keep updating this thread. new pics in one week.

Thanks to all who replied.

UPDATE

No pics right now, maybe next weekend.

The plant has no improved much. Leaves continue to curl. Phosporous deficency continued to show even after I fed her.

after talking with some local friends, i have come to the conclusion i have bad watering habbits. I wonder too much. I believe this is what is causing the leaf curling. I had been using grow bags and I don't think my drainage has been good enough. I cut open the drain bag from the plant in question and it was mush in the bottom, smelt really bad. Not what I should find.

I got off as much of that soil as possible and then re-potted into a new 5 gallon pot with miracle grow potting mix that i added some per-lite too. Before I do anything else I really want that root system to dry out. I may not water it until the weekend.

I think i water too much, but i also think the drainage in these grow bags was not sufficiency. I am going to stop using them. I also feel like pro-mix compacts after watering really easily.

 

[greenguy78]

Thanks to all that helped in this post. The cherry slider has bounced back big time and seems to have turned the corner. I will attack some pics of her later today. It hasn't happened fast but she is on the right path now.

I think more than anything I have been over watering and that led to my other troubles. Thanks again to everyone who chimed in when i was in need.

 

[shnkrmn]

Pro-mix does compact quite a bit. I use about 40% perlite to address that.

One of the great things about grow bags is you can add as many drainage holes as you like. I still don't use em, they are a pain to handle.

Glad to hear things have improved.
