At wits end with these plants, what is wrong with this plant?
    #420190 - 05/18/10 11:11 PM (6 years, 6 months ago)

Soil Growers:
1. seed
2. 9 days into flowering
3. 12-14 inches
4. 5 are in 6 inch and 2 are in 8 inch
5. Ladybug Organic soil with added Perlite
6. Water when they get light and dry with Distilled water
7. 6.5-7.2
8. FF Grow big 6-4-4 soon 2-8-4 FF Tiger Bloom
9. no foliar feeding, scared to
10. fluorescent, 196 watts
11. 12 inches from lights, were alot closer when the were younger
12. Grow space is 6 sq feet
13. Temp is 80-83 with light and 70-73 in dark, 20-30% humidity
14. Soil ph is around 7
15. no bugs
16. First grow

I have gotten over my overwatering issues
but now I have this?



I'm thinking Magnesium?  I water when they get dry and light.I fert every other water which is about 8-10 days

These plants are driving me crazy.  If its not one thing its another.

Give us some pictures of the whole plant.  Are you measuring the runoff to determine the pH of your plant??

How much in ml's per gallon are you giving of the nutrient solution

Looks kind of like a Potassium deficiency I had. You should definitly check your phs first though .

So check the ph of the water before and after and the soil? Correct

So check the pH of nutrient solution that's going into your soil.  Collect the runoff and read that.  If you have a starting pH of like 6.5, and your run off is 8.0  Then you know the pH of your soil is going to be way above 8, probably more likely above 9 if it's that drastic.  It's not the most accurate way to check the pH of your soil.  But way better than all the other home test kits that they sell.

Will do that.

I test my waters pH by adding the drops to the water and then comparing the color of my water to the color chart on the bottle.  I feel that it is hard to distinguish between 6.5 and 7.  Is there a better way of testing pH, a more expensive way?  I don't really trust my 3 prong digital soil pH tester either...  It test my soils pH at or right above 7.  Anyway will see what happens.  may have one plant to water tonight.

Some pics to help.  In defense of the sad looking plants, there was a point when I thought I had killed most of them do to pH because I used tap water to water them the first few times.  Much of the leaves died and fell off.  They recovered fast after I started using distilled water, added some fert, and began checking my waters pH.  The best three turned out to be 3 males, go figure...  They are kind of doing the same again but not as fast as last time.

One of the worst ones

You can buy extremely accurate ph and salinity meters would cost a fair bit though and they need to be Callicrates all the time with a solution u know is a certain ph

Hawk, to answer a question you asked above, I use 3 teaspoons per a gallon of distilled water of FF Grow Big.  I then use pH up to bring the pH back to 6.5 - 7ish range.

Question.  Why is the pH of distilled water not always 7?

Inbred_gimp, what kind of pH testing equip do you use? Or what kind do seasoned growers use?

Go down to your grow store and ask for a hannah digital pH meter.  40-80 bucks depending on the model you get.  Very accurate and you don't have to calibrate that brand as frequently as Milwaukee.  And they're super easy to calibrate compared to the Milwaukee brand. 

Man your plants look really good.  I wouldn't even be worried about those couple of bottom leaves.  Since they're so low they are going to be getting a lot less light and and that makes the plant suck nutrients out of them and then sheds the leaves. 

So you using 15ml's per gallon.  Seems a bit high for being under CFL's in my opinion.  Luckily your in dirt so it can help buffer it. 

On a second look at some of the leaves.  You might be getting some toxic salt build up.  Are you doing that feeding regimen with every watering??  Have you flushed these at all??


Another note.  Don't go straight to the Tiger bloom, do a slow transition over to it.  3/4 grow-1/4 bloom, then 1/2 and 1/2 and so on.  Don't feed with every watering.  Do every other watering.  And bring the amount your giving them down IMO.

First off, thanks hawk, for the positive remarks.  One thing I have noticed about new growers is that they can be very hard on themselves.

I do only use fert every other watering and no, I have not flushed yet.  I was hoping to only have to do it once, but twice will work.  From reading, I know one flushes with pH adjusted water equaling 3 times the volume of you grow medium and you spread this out over the course the day.  Should one add any fert during or at the end of flushing or just wait till the next watering?

Thanks as well to the advise on switching over to blooming ferts.  I never would have considered that. 

I can't wait to grow again to learn from all of my first time mistakes.  and that's with a month plus of reading and research.

All of the water you flush through your plants should be a VERY light nutrient solution, or with Clearex.  If using Clearex I would make the last gallon of water I put in have nutrients.  It's always recommended to Flush a couple fo times through a grow.  Helps prevent problems from popping up.

Plants are looking great dude like hawk said I wouldn't stress toouch about the lower leaves dying they seem to die off and come back with little shoots where they fell off from

Thanks gimp.  I do appreciate your kind words.
 
Side note.
I used a teaspoon of epsom salt/gallon during the last water on about half of them and I have never seen my leafs so at attention as they are now, well the ones that did not have spots everywhere.  They seem to be perking up.

will flush this weekend.

    #422254 - 05/22/10 11:00 PM (6 years, 6 months ago)

Today the plants were watered with a light fert solution (about 1.5 teaspoons total) half FFgrow big and half FFTiger Bloom.  The pH going in was 6-6.5 ish and what came out ranged from 6.5-7.5 maybe even 8 on one. They still seem to be doing much better since I added the Epsom salt in there previous watering.  I decided to keep them on their regular feeding schedule and flush them during there next scheduled non nute watering.

Question, when you flush, do you use neutral pH water, or do you lower it a bit to bring down your pH?

I'm going to say it, I'm new and a new grower this doesn't seem to be a PH.


I'm new and I'm about 99% sure it's a magnesium deficiency, I'm willing to bet my reputation on it, the one I don't have)


Magnesium deficiency starts off in the older leaves first.
It starts at the end of the leaves and works its way in, like such.

I also bet those brown spots started off yellowish and turned brown, which is what magnesium deficiency will do

The tips of your leaves are curling up.


The only sign it's missing is the sides of the leaves are going to curl inward, they're praying for MG lol.

Mix about 1 tsp.(teaspoon) of epsom salt/ 1 gallon of water. Your water may have a high ratio of PPM. You could be locking out the MG, the epsom salt will help just make sure you don't end up reversing it and locking another nute out.

That's my diagnosis and I'm pretty proud of myself.

I did add some epsom and it did seem to help drastically.  However upon testing the pH of the runoff,  I would say that a few of them have soil with a high pH as well.  Thanks for your input and suggestions.

Ok, so another question.  After flushing plants with 1/2 teaspoon of fert  per gallon Distilled water solution (half grow big/half tiger bloom), should the next watering be with or without fert?  If so reg. strength feeding or other?

thanks
