If researched symptoms and different deficiencies and problems but have not been able to figure out the problem, this plant is outside and i feed it with two part general hydroponics formula... looks like it might be a defiency of some sort but i have another plant next to it that is the same size and looks totally fine... I have spent over an hour looking around and reading but could use some help.

leaves turn brown in spots and then either slowly or rapidly turn yellow and wilt... seems to effect random leaves, dark spots have been starting in middle of leaves and/or on sides of leaves, could it be a fungus or something? thank you in advance... these arent the best pics, ill have to get my camera back to take more...

It seems like you are locked out for quite some time.... nutrients like GH typically drop PH a bit. Not knowing exactly what the PH your watering with is can lead to issues like this and worse <gulp>.

You have time relax.... its a weed..... killing them could make you rich by selling your recipe to the many tomato gardeners who break their back daily knocking them back.
However our weed is precious.... it requires proper care and attention to achieve its potential.....

take my advice i can assure you that they are not lacking any fertilizers as you have burned them with nitrogen trying to compensate for whatever you thought they may have been lacking.

take a walk to the store grab a few gallons of that water they spit out of those 10 cent refill R/o machines at most supermarkets (at 8 lbs a gallon i wouldn't walk to far)

add nothing to the water and pour it untill you think you just killed the plant with too much water..... trust me you didn't. flush away that bad stuff floating in there..

begin light feedings again after 3-4 days and try to invest in a ph meter the chart below will show you the P and K are quite low in your plant mostly likely with the acidic water you been feeding is my guess. and almost positive. if you can transplant do it asap..... soil bacteria take much longer trying to repopulate acidic soil with so many of their dead counterparts lying around them. ;p

first of all thank you for the two replies especially Boombats! i bought a ph meter off of amazon, and i just didnt really trust it, i was hoping to be able to do this by eye, i thought this also might be from over watering too... ill try my ph meter more but i heard you have to buy an expensive one for it to be accurate.. also ive been watering my plants with filtered water, and with my ppm meter it tested at 9, so very low if thats accurate my regular tap water is 200 ppm... i will look into checking the soil ph now, i have ph up and down never used it yet... im a noob... i have some plants inside too but i know what the problem is i over nuted them and overwatered and let some of them get too close to the light because i waited too long to flower they double in size i didnt read that on all the threads when i started researching bud... although ill be getting some from that the buds are growing slowly at least, next time it shall be better... i will water down the soil to get the excess stuff out... does filtered water still have much higher acidity vs the water bought at stores in general?

ok, i checked, ive been watering my plants within range of the ph your chart says, but when i flushed my plants i checked the ph of the runoff and it was about 5.5 if my ph meter is correct... could me over nuting my plants have caused the Ph to become more acidic or do people generally have to ad Ph up here and there with the Grow and Bloom formulas? thanks again.
