help yet again!!

Pics would help greatly. If we can see what the plant looks like, we can better diagnose what your problem is. If you don't have pics, try giving a more specific description. Are the leaves turning any colors (like yellow/brown maybe?), what's the temps like in your grow room? What's your watering/feeding schedule, and at what strength (if any) are you're nutes? Also, how old are the plants, and what stage of growth are they in? These are all answers we're gonna need to know in order for us to help you.

It could be over-watering (the most common n00b mistake, btw, so don't feel bad if that's the case)...

But yeah... Pics would help, but if that's not possible, answer the questions above, and I'm sure someone will be able to help you.

EDIT: Also, what type of lighting are you using, and how many watts/lumens? And how close to the plants are they?

 

Im no expert but it does look like overwatering to me....

 

It looks like it could be anything from overwatering to heat stress. You might want to re-pot that, also. It looks like it's in a tiny pot for how big that plant is. But I'm not sure, I just don't know enough from the pictures.

 

That pot looks really small. You want a minimum of a 3 gallon (5 preferably) if you expect anything decent from that plant. You should water when the soil is dry about 2 knuckles deep. Also, what are the temps like? If you don't have a thermometer, put your hand on the tops of the plants (palm down) - if the top of your hand feels too warm for comfort, then chances are it's too hot for the plants, as well. Also, are you using any fertilizers? Or was the soil you planted in pre-fertilized?

 

If they're getting root-bound, that could be solved by repotting them... What types of nutes are you using, and at what strength? If you already switched to 12/12 you'll wanna do that repot asap. You don't wanna stress 'em out too much while they're flowering and shit. Also, you want a fert that's low in N and high in P and K (the numbers on the fert box just incase you didn't know, like 5-5-5-, or 5-10-10) for flowering.

 

watering with normal water after repotting was good. As for that ferilizer, you really do want something with very little N and more P and K. That stuff might be alright, but I wouldn't give it to it.
Instead, I'd find a hydro store near you and get some organic flowering nutes there. Fox Farm has really good organic nutrients that come as either water-soluble powder or liquid and aren't all that expensive. Advanced Nutrients also has really good nutrients which seem to be made specifically for weed growing. Just make sure it's for flowering and the N values are low with high P and K values, usually P being the highest.

 

and/or over nuting

overnute without flushing makes the plant conserve what it has to avoid drinking up the shit thats already knocking the plant eq. of a liver


flush them throughly then blot excess water off the topsoil
