Help please! Leaves with spots and curling!

Does anyone know what this could be? Thanks for any input!

Could you please put some more information on your grow?
Will really help us determining your problem.

Temps, Humidity, Feeding Schedule, Watering Schedule, Age, Soil type and Composition, Fertilizers.... that sort of stuff

right now this plant is in a veg state. It is in fox farm soil. Watering schedule is on a as needed basis, no set schedule. Temps stay at 75-77. I really have not put any nutes on these guys yet either...also are 2 months of age.. thanks for the reply, any answers would help a lot!

I think you should be feeding them now friend.

"After sprouting, cannabis plant starts vegetative phase and growers wonder what is the best fertilizer for marijuana growth? If growing marijuana in soil, you should water feed (no nutrients, no fertilizers) the plants for the first two weeks. Almost all good soils will contain enough fertilizer for the plant to feed on during that time. Plants are delicate at this stage and can go for a week or two with a minimal amount of food. After that you need to start using marijuana grow fertilizer. At the maximum, use a solution that is no more than 50% of the strength of the recommended level. That is, if the fertilizer manufacturer recommends mixing one tablespoon to every gallon of water, you should add less than half a tablespoon of nutrient to every gallon of water for the first two weeks after germinating. Do not give your plants extra fertilizer thinking it will make them grow faster. Too much will kill your plants. If you under fertilize, plants will take longer to grow but will not die. Follow the mixing instructions on the package, if you aren't sure, use less rather than more."

Do some research, find some fert's that best suit your needs, start low and increase the dose. I believe what is happening here is the plant is using the lower leaves to feed the new growth.

Also how close are your lights? The plants seem to be stretching a fair amount?

This may also help you a little more if you wanted to use fox farm Nute's and also its a feedling schedule that shows how much you should be feeding in soil!

Just watch your pH!
That seems to be the problem too often(maybe not here) but you really should invest in a pH pen (I recommend Hanna) and maybe doing a little homework as you may run into lock- out and other problems... Peace

im no pro but i give nutrients during cloning and straight threw entire process, i start off slow and build up. does anyone think that those spots could be spider mites, thought thats whtat that looked like

thanks for all the input. Im going to try to a little dose of nutes on the next few waterings and see how she goes..As for it being spider mites, that isnt the case as I have had that issue before and know what it looks like..

They look more like 2 weeks than 2 monthsI'd give'em 1.5 tsp grow big and 2 tbs big bloomThen they will really take offsee how the leaves are laying flat~when you feed'em~watch'em fold up like their praying

U burned it. Either by over nuking it or it was too close to the light at one time. I'm leaning towards too many nutes.

Not burned because I have only nuted once, and it was extremelyyyy little..

how hot is it in grow room and what lights u using and how far away is light from your plant
( looking at your pics ) heat stress

is the yellow working its way up the plant slowly ?

repot them look for brown roots. break the root ball up a bit put it new soil. looks like fungus don't spray before lights out.
