Dried Curled Leaves, slight brown spots, help!

[Agouti]

I'm doing an indoor grow, soil. I have these puppies set up with a 1000 watt light in a 5x5 tent, with the light being air-cooled, 2 feet away from the plants. Right now the plants are in vegetative growth. I'm giving them a nightly watering with synthetic fertilizer (a vegetative growth one, high in nitrogen, it's called "Ionic Grow").

The soil is your basic promix hp.

So what's going on here? Is this too little water? Too little nitrogen? Any help would be greatly appreciated.

The new growth looks happy, give another day or two, sometimes those first couple o leaves look strange, goodluck.✌

 

[GreeeeN GRassss]

first of all move the light away from them. a 1000 watt light is very strong for your litttle babies.

looks like nute burn to me. how much are you feeding them

 

[Nichead]

Looks like too much light. I have a strain this grow (mystery-bagseed), every one of them does that when I put them directly under the 600w MH. Moved them to the edge of things, they look healthy as can be now. 1000 watts for little plants like that sounds like overkill, I'd raise the light a bit until they grew some new leaves. Or, al70 has a point, wait for those new leaves until you get worried.

could be that the soil and/or veg nutes were a little too hot for the young plant...back off with the nutes for a sec and see how she reacts..

 

[al70]

Furrywall is talking sense, soil is to complicated for me, I use coco, two feet should be ok �� for a big fire like that, I think it's possible to check the ph o the soil, wait a little while, goodluck. ��

Dy'a have a fan blowing over em ? ��

 

[Agouti]

It was doing this before I ever fed it a drop of nutes, since then I've used Ionic Grow. I'm watering nightly with a well draining soil, lots of perlite, and I'm using half the concentration they recommend. 10 ml / gallon. (or two teaspoon per gallon, instead of four)


Also, I've had the lights turn down to 65%, with a digital ballast for what it's worth.

The plant was starting to do this, however, when I had it under nothing but LEDs, however the brown spots weren't an issue then.


Should I just raise the light to the absolute top of the tent? Or do that combined with spreading the plants to the edges? I'm using a magnum low pro, which does quite a good job of spreading the light out everywhere, and I feel that raising it to the top, will do an even better job, and thus will make spreading the plants to the edge entirely null.

However, it never hurts to try. The other plants look more or less healthy, idk. These were all grown from seed.

Dy'a have a fan blowing over em ? ��

Yeah, I have a really small fan in the corner, but it's more blowing past them, nothing is in the direct range of it. Also, I think they move from all the suction blowing over the light. One end of the hood is open, and other is attached to tubing with a can fan max fan pro series 6 inch, which it blows into a sizable filter.

You water everyday?

The pot never dries?

 

[Agouti]

Oh no, the soil right now in there is somewhat dry, like regular outside dirt. It's not parched, and not soaking. It drains fairly well. However, I did have them in small cubes for like 2 weeks, and those were always soaked. And when I transplanted them to the new 1 gallon pots, I didn't wet the soil down first, because of issues with carrying the wet pot to the tent, seeing as they were filled with promix in the garage. I then water them quite well once in the tent, but have no idea if this will have any impact.

your over watering let the pots dry out your not growing in coco, raise the lights and let the plants adjust to the stronger light. even at 65% that is still 750 watts. at that stage my plants grow just fine under a 200 watt cfl

have you an EC meter?

I don't have an EC meter, can you explain to me what they are?

I'll raise the lights up as far as I can get them, and see what it does.

Is there some way to test the water level in the soil, and some number I should be looking for?

 

[GreeeeN GRassss]

an EC meter will measure the strength of your nutrient solution.

a good way to tell when a plant needs water is by the weight of it. when it gets lighter then you know it needs to be watered.

 

[BigPete]

Plants do better watered in the morning instead of night time.

 

[Agouti]

So should I wait a few days between watering? Also, the soil seems as dry as regular soil outside, but not the bone dry parchedness it had out of the bag. Is there some sort of magic number I should shoot for with a soil water saturation meter? Or is there something I should be feeling for with my fingers?

 

[al70]

Try coco, for next grow, with coco nutes, new triers I believe struggle with soil, I hope ye get sorted I hear the way yer goin is a beautiful smoke,start at the bottom n work yer way up,goodluck. ��

 

[GreeeeN GRassss]

with 750watts beaming down on them the soil will dry out.

next time you water feel the weight then wait a day or two and check again. even in coco id only be watering them every other day. wet dry cycles also helps to build roots.

dont kill them with to much love, it happens to everyone

good luck

I raised the light another foot and a half. And it's the second day now of no watering. However, one of the leaves on another plant showed an irregular banding pattern on the leaf. I'll take a picture of it later tonight.

It looks dead to rights like this illustration I have of magnesium deficiency. Should I supplement with magnesium? What is a good brand of "fertilizer" to introduce micronutrients? Or alternatively, when I move these things from a 1 gallon pot to a 5 or 7 gallon pot, is there another soil aside from the bp promix that contains all of these nutrients already it, or that I could add to promix?

 

[Agouti]

Here is the plant I showed earlier. The bottom 2 leaves have become worse, but the top growth all appears to be relatively healthy. The light was raised an extra food and half, and it hasn't been watered in 3-4 days. (I think tonight will be a watering).



Here is another plant I mentioned earlier that displayed the beginning of Mg deficiency.


Overall, I plan on transferring these plants from a 1 gallon pot to 5 or 7 gallon pots, but I'm wondering if there is some soil brand that could be recommended that is NOT inert. Right now I'm using promix with the above mentioned fertilizer (ionic growth), but would like to mix this when I move them up to larger pots with a real soil, not this inert soil.

I've read about fox farms, roots organic, and ocean forest. Would I just be better off going to an organic nursery?
