New growth Lime green/yellow and thin growth
    #511563 - 01/06/11 11:46 PM (5 years, 10 months ago)

Soil Growers:
1. Are you growing from seed or clones? Seed
2. How old are your plants? 44 days 8 flowering
3. How tall are your plants? 12 inches or so (have been training them)
4. What size containers are they planted in? 8 inch pots
5. What is your soil mix? FFOF
6. How often do you water and what type of water do you use? 3 - 4 days when needed DISTILLED
7. What is the pH of your water? 6.8-7 now.
8. What kind of fertilizer do you use and what is its NPK ratio? Tiger Bloom 2-8-4 fed once 3 days ago 2 teaspoons per gallon
9. Do you foliar feed or spray your plants with anything? no
10. What kind of lights do you use and how many watts combined? (HPS, MH, fluorescent, halogen, incandescent "plant lights") 300 watts of CFL
11. How close are your lights to the plants? 6-8 inches
12. What size is your grow space in square feet? 6
13. What is the temperature and humidity in your grow space? 75-80 lights on 60-70lights off  Humidity is 20-30
14. What is the pH of the soil? Run off just tested.  pH water in 6.9  run off 5.9 - 6.1
15. Have you noticed any insect activity in your grow space? no
16. How much experience do you have growing? 3rd grow

For starters, the FFOF soil has been hot from the get go.  I fed once 2 weeks ago with Grow big (1 teaspoon per gallon)and 3 days ago Tiger Bloom (2 tea spoons per gallon).

The new growth on three of the four plants is lime green/yellow (base to tip on the bigger leaves, and all of tiny new growth), twisted in spots, and very thin.    Also in just a few spots the very small growth is burnt.  There really has not been much new growth for the whole flowering period (last 5-7 days).  One of the plants has yellow tips and a few burnt tips on the fan leaves.  The only good looking plant that has any signs of  flower or leaf growth is the plant that had its topped ripped off (accident) a few days ago.

My guess would be the soil's pH, based on the run off reading.  I don't know how it got that way?

What do I need to do to go about raising the pH of my soil?  I just watered 2 plants 30 mins ago with 6.9 distilled water.

or is there something else contributing to this stall in growth. 


Please help.  these plants need to start taking off

I watered the other two plants today. Used pH 6.9 distilled water.  Run off was 5.3 & 5.7

I decided to flush one plant from yesterday.  I used 3 gallons of distilled water with about 10 drops of  tigerbloom/growbig (6/4 drops), and I adusted the pH up to 7.1 with 10 drops of pH UP and an 8th teaspoon of baking soda.  I got the run off up from 5.7 to 6.3 by the end of the flush.  the flush took 4 hrs. 

Was this the correct way to flush and raise my pH?
If so I will repeat tomorrow with the other 3 plants.

I'm no expert but I've often read that you should generally water with 6.5 phd water. It seems to me you did that flush correctly. You did raise it and I'm sure that amount that you watered with was 2x-3x times the size of your container.

Thanks.

I decided not to flush any of the other 3.  I will see how they look at their next watering and If I feel they are worse at that time, I will flush. 



Anyone? Should I be using big bloom after Grow Big, or a combination of Big B/Tiger B?  Using Tiger Bloom at the low end of Full Strength (2 tsp/Gal) seemed to make the soil's pH plumet.

I have some seedling in similar condition, also flushed and they're staring to look better already!

could the stall in growth be caused by temps from 58 - 65 during the lights out?

I've been looking at this a little and with the new pictures I'm wondering if those ladies are hungry..But I'm still not sure.

I don't think the temps are hurting it, could be wrong though.

Other than that they really don't look BAD. I see what you are saying but that yellow/light greenish growth can be normal right after the flip to flowering during the stretch.

The pH of the soil could also be a culprit of the slow growth.

Watered #2 today, first pic the far right plant, with Distilled with pH 6.9.  Run off measured 5.1. 

I also worry that they need food, but everything points to a hot soil or pH issue.  There are signs of slight def, but I think its just a lock out issue.  I can't feel comfortable feeding again if the tiger bloom is just going to make the pH plummet more...

I'm going to water them twice between feedings untill I'm certain the soil's pH is improving.

The good news is they don't seem to be getting worse or at least not a at a noticeable rate.

I went ahead and flushed #2 (far right pic) got run off up from 5.1 to 5.9.  I used 3 gallons.  the first 2 were plain distilled and the last had 5 drops of Tigerbloom, 3 of Grow Big, and 9 drops of pH up.  All three gallons pH 6.9 going in.  I filled the pot every 30 mins for 5 hrs.

muse,

That lime green growth is definitely a plant's reaction to low temps. You'll see that in young or old plants when temperatures drop that low in vegetative states.

Your PH seems fine, if anything, don't worry about it too much. 5-6 is safe with soil. Next time, you might want to consider putting in a soft buffer like hydrated lime, or oyster shell into your soil mix. Doing this will bring your ph up, without using a lot of chemicals. That just gets expensive.

Thanks.  I think I'm going to add some crushed Oyster shell in, since FFOF already has some in it.
