these are the ones i beleive is nutrient burn,





now this one, is not showing the same symptoms, there not dried up they curl, but not yellowing almost one can say they are going white, light brown idk..heres the pic





if anybody have any idea what my problem is and how i can fix it, its mos def much appreciated, i looked over the symptoms sheet and cant decide what this last one is, i strongly beleive the 1st set are nute burn, could be wrong......

IME, nutrients burn damage is increased by heat

so I'd try flushing soil and lower nutrient levels then check again

Well since no one else has said it.  I can gurantee that you're overwatering your plants.  Watering everyday without fail is a no no.  You only need to water when the soil is dry.  You can do this by either feeling the weight of your pots, or by the moistness of your soil.  i reccommend using the weight technique.  Let your pots get really dry and then feel how heavy they are.  Then water them until thoroughly saturated.  Then feel how heavy it is, voila a fail safe way to determine when they need watering.


Now I'm sure that this problem is being coupled with a few other problems.  One your pH was obviously WAY off.  That alone will fuck up your plants like your seeing, even if they are getting the appropriate amounts of nutrients, they wont be available to them.

Thank you Hawk. I was getting worried scrolling through this thread when I realized nobody had said that yet.

Also, a 10-52-10 fertilizer for veg is quite frankly insane.

Yah confirmed nute burn by the yellowing, nitrogen. Just back off the nutes and use more water, dilute the nutes more. Sounds like you are aware of the heat issue as well. I'd shoot for larger pots as well and try to care about my plants multiple times a day; as that is basically required.
