Too Damn Slow !!!

Looking for feedback on growth rates, these things are growng so slow it can be hard to see any change at all in a 10 hour period. In a 24 hour period growth can be seen but it's not much.
These are clones who have been in soil for almost a month and as you can see they're not exactly impressive and the leaves are really quite small, I'd say not a single leaf over 2 inches long and most closer to an inch.
Two Sour Diesel, two MK-ULtra and one unknown.
Here's some relevant info:
- Vegging under 100W CFL (500w) (~6500 usable lumens)
- Area is ~1.5 to 2 sq.ft.
- It has been getting over 100 degrees occasionally but cool days don't seem to make much of a difference in growth!
- Had a slight nute burn hit two weeks ago, no nutes since then.
- Watering with Reverse Osmosis water w. 2 drops superthrive, 30ml hydrogen peroxide, 100mg alfalfa 'tea' per gallon, adjusted to PH 6.5.
- Soil is 75% Supersoil and 25% perilite.
- Doing gentle low stress training on all except the smallest unknown plant.
- When clones were first obtained and planted they came with spider mites which has since been mitigated 99% with neem oil.

Is this kind of super slow growth normal under these conditions?
Internodes are super close due to the CFL light but still...... at this rate vegging will be needed for months just to get a couple of tops to reach 12" in height before forcing flowering.

FYI, the LST may make it look like there's more than one plant per picture but there isn't.

Any feedback much appreciated!

Well Bulster I'm no expert, but i think you have a combination of problems here..

You can obviously see the fert burn, but also some kind of nutrient deficency is present, possibly N, because of the yellowing, but that could be because of some lock-up thats going on (although I wouldn't want to advise on what tho).. You're adding PH adjusted water, but have you tested the PH of the soil?

The soil looks a bit peat based for my liking, i'm not familiar with "Supersoil" tho. I would have added a lot more perlite.

You also say you have days over 100f, and other "cool" days - massive differences in temps will also stress the plant.

They just look generally stressed out, i'd just see how things go for a coupla weeks.

Keep us posted!:thumbsup:

Yep, heat, mites and nutes are to blame for sure there m8. Have you flushed your clones at all?

No flushing has been done. I guess a mistake was made by putting small clones in big containers to save them the transplant later. Now if they are flushed I'm afraid they will rot as it will take forever for them to use the water.

Thoughts ?

Thanks.

do a flush on all ur plants and only use distilled water with your superthrive ive been using super thrive also and two drops for every gallon i think you should deff do something about your heat prob's if not u might get one female if ur lucky

just tone things down a bit and see what happens i think you should maybe starty a couple seedlings just in case all those turn out to be males/hermis they both suck!!!

Just because small plants are in big pots won't make the roots rot. So long as the soil is light and drains well you won't expereince a problem in that regard.

sorry to see that bro.MJ is a resilient plant though .i would go with what smokinbudz said. cool it off atleast to about 85f and keep the temps steady. i agree get some backups ready. peace

use sand dude

not use sand from the beach they are to salt for the plants, i think you have to flush it and the last water use nuts half strenght. you can use one fan blowing your plants they get cooler and stimulate growth. other thing, i think they are to small to LST.

Try to get new clones or new seeds , and dont make the mistakes you did again. It is hard to get them back especially if they are a more than a month old.

just my thought.

Here's an update.

- Added larger fan (swamp cooler) to blow across the top of the plants to reduce the direct heat from the lamp. Now it generally doesn't get over 90 degrees in there and RH is still never over 40%.
- Did a heavy watering with plain ph adjusted RO water.
- Decided not to do anything drastic and just see what happened. Ready to sacrifice if necessary.

Took a few days but what do you know, all of a sudden everything just kicked into high gear. They have grown more in the last few days than in the previous month and signs of nute def's are going away. They are all looking strong.:D

Thanks for all the tips!

throw that damned SuperThrive in the toilet where it belongs ... it only helps with rooting (good for cloning, but you are not cloning), and will kill your plant if overdone ... you have several issues going there, besides ... best to read a good grow book, and start again the right way ... sorry to sound so pessimistic, but, 'been there, done that' ... :smokin:

I guess I wasnt specific, sorry ... you dont have enough light ... your pH is probably way off ... the SuperSoil already has nitrogen included, so you should not be fertilizing until flowering ... temps were way too high ... mites certainly didn't help ... and, why the hell would you be 'LST'ing a plant two inches tall ??? ... hope this helps, as said, start over AFTER reading a good grow book ...
