Leaves not looking so good, any thoughts?

Alright been growing this plant for few weeks now, thought the lower leaves were just turning yellow and dieing off like normal, but i dont think so now.

Bag seed
DWC 2 gallon
PH water little to no nutes
Almost 24" tall

Leaves on the bottom started falling off like normal since they dont get much light, but now its going up to the leaves that do get light. A few of the leaves started crusting on the tips, some turned (see in the pics). Then the leaf starts going from a green to a lime green then few spots might show up (brown), then the leaf goes yellow.

Not really sure what it is, been looking through other threads and i will keep at it but have not found anything yet that looks like it.

Anyone know what this is ?

Been awhile since I have tried diagnosing a plant deficiency, so mind me if im incorrect.

I'd say nitrogen. Google Cannabis Deficiencies



EDIT: Magnesium may be the correct answer.

Try here if you think i'm incorrect. https://www.rollitup.org/marijuana-plant-problems/285085-marijuana-nutrient-deficiency-table-report.html

Ya man i think for a plant that size you probably outta be giving it more nutrients. However, i usually tend to find one weak plant out of my garden and im starting to wonder if maybe its just bad genetics..

It might be not sure, it is bag seed not always the best seeds but hey its big. As for the nutes i was at 1.2 ec but then after this started moving up the plant i switched to like a flush just Ph water.

Thanks Mike will be checking out the links right now!!

Still new to even trying to diagnose plant problems wish i was better at it, be like just see the plant and know what to do with out looking up info, but that will come with time and practice.

I was even leaning towards Potassium, not sure

My nute line is House and Garden so i will be giving the plant a Foilar spray soon with Magic green, its not a miracle cure for problems but it supposed to help

Rip

Ok its been 5 days and now both of my plants look like shit , its my fault been working on the flower room yet agian , and did not really take care of my veg room, noticed the water was getting low so i just gave them my ro water i had, but i did not ph it so i know thats one of the problems.

anyways flower rooms about done just minor detials(will be posting a new thread with it some time) so i was thinking of putting them into flower.

been flushing for a day now and they dont seem to be getting better, my ph meter went shit on me so am using the old style drip color ph kit. i know it takes more then a day but anyways just bored and wanted some feed back, dam wife just looks at me like uh duh no help but then agian she knows nothing about growing

anyways, anythoughts on the subject? just put them in flowering or figure out whats wrong and fix it first

bla for all

Pic 7 looks alot like a phosphurus deficiency. I think your problem is just an overall nutrient deficiency. You gotta feed them man, at 24 inches and no nutes they look starved. Try adding something like a 10-10-10 fert and i would keep them in veg until healthy.

pic 6 also looks like it could be light burn. I've had leaves ontop that were fine but lower leaves show signs of burns before, but never than bad.

Never seen aluminum foil as a cover B4, I'm primarily a hydro guy tho, done soil too but only veggies. Theory: Foil retaining heat so roots are too hot? and also generating hot spots/elevated temps at the base when the gro light hits it?

Its reflective tape not foil.

and did not get the last part, if you could explain a little more.

he thinks your foil tape may be insulating the roots and overheating them and that the light reflected off the foil is causing hot spots. I say no way to the hot spots, its not close enough to the light and its not really direct light cuz it has to travel past the plant. As for the foil insulating the soil, stick your finger down into the dirt about 5 inches and see if its hot, or try a thermometer. you might try putting a few holes in the foil to get more air to the roots.
