Plant Moisture Stress - Symptoms and Solutions

Paulo, I dont think you can link an img file from your pc, you have to use a filehosting service like photobucket. Oh, and I think the edge curling you are experiencing could be an early sign of over watering. I know for me, one of my biggest problems is watering my plants too much, I always want to feed them thinking that will make them grow faster, but the soil needs time between watering to dry out a little. If it is constantly soaked it will be more of a problem than being helpful. SOrry, not trying to hijack.

Uncle ben, what do you think of fluorescent lights for cloning? I have 1 18inch t8 bulb over a 45 site cloner. I usually use HPS lights in my garden, so I am not use to using these fluorescent lights. Are the t5s that much better/brighter? I have a pic of my cloner setup here...

The reason I ask is I am thinking of upgrading my lights. I want to get 2 24inch t5 lights to replace the 18 inch t8 I have now. Oh, btw the bulb is a 6500K color temp bulb that I am using.

As long as you have plenty of light for photosynthesis, I don't see why that would be a problem.

I'll have a look. Just to clarify my position, if anyone is into organics, it's me. I'm just not into the hype of the green movement.

Yea i wasnt sure you fucked with organics , but i guess the only way to stress your point , is to stress the ratio's and what the plant sees/wants , no matter wether it be organic or inorganic.
Im not too far into the green thing. I have always liked organics , its what i started with , so i'll stick to it.
I almost cried when dumping MG in my soil, but my babies through out a sigh of relief.

I have decided never to use anything from the hydro store again. (sure there is plenty of good shit in there) The marketing and the hype is sickning. The store owners (most) are no better then big mike. everytime they get a new product ..... its the same thing.... "All of our customers say its very good and they could not go without it" now they even stoop as far as going on utube and saying "our product is not the best..... this other 500 dollar one is ..... our scientist......bla bla.. PUKE. How in the fuck did politics get into weed .........oh its always been like that.
Sorry for pouring a river in your thread ub.
it happens to all of us sometimes.

keep um greem :bigjoint:

are you the same uncle ben that's in marijuana horticulture book by jorge cervantes?
Yep.

In general, a great book with alot of excellent color photos. The chapter on lighting is worth the price alone but Jorge doesn't always get it right. There are some inaccuracies like the ditty he put in on my experiment with Griffin's Spin-Out.

Hey UB,

Im about 2 weeks into flower and all is really green and growing good, but i am getting some leave curling the long way like a canoe and even a little tip curl.

Not on all of the plants though. The funny thing is it is affecting the big fan leaves of the small sativa's and the small newer leaves of the indaca (witch used to be a mom).

At this point i only have 1000w on a 4x8 tray.

I keep my temp 60-75 and RH 40%

I water with a drip every 1-2 hours for 15 min.

My ph is 5.9+- .2
ppm is 1250
I attached some pics of a smaller leave . I didnt want to remove one of the larger ones because the plants seem
really green and healthy except for this issue.

Please Help

I wouldn't worry so much about the leaf curl, but lack of leaf mass. What NPK foods are they getting? 1,250 ppm may be too high for their requirements.

When u say leaf mass, do you mean the amount of leaves or the size of them?
My partner talked me into a semi lolipop on them. But we didnt cut any fan leaves just the lower bud branches.
I will take some better pictures after the light goes off.
These plants went to flower very small.

I am using GH Flora Nova
grow 2-1-6 (just a little for the first couple weaks)
micro 5-0-1
bloom 0-5-4
Vegan blendblend .5-1-1
kool bloom boost 0-10-10 (very small amount so far)

I am using these nutes at roughly 1/2 strength of what GH reccomends or the ppm is thru the roof.

So you can over nute without getting the burn?

After i talked to u I a few weeks back i started a thread with a lot of detail about my setup and i think this issue.

You just reduced plant health and production.

Not enough N.

I argued the lolipop to no avail. Our last crop had a lot of small buds all over. i thought that was good. He says just a couple big ones. We will see.

So should i add more micro(5-0-1) instead of grow(2-1-6)

3-4 feet on the short ones but only 16" on the two moms.

The sativas are stretching pretty good but the indacas stay real short.

I get advice on both sides of the coin when it comes to the height of my light. But i will listen to more.
