Low Ryder Easy Rider. Soil. Drying and Browning of leaves

So i took a look at the stickies - seems some pictures are missing so it doesnt do it justice... but here is my issue:

Plant: Low Ryder easy Ryder
Medium: Soil from walmart. no fert in soil.
Water frequency: 2-3 times a week depending on the weight of the pot
Ph level: about 7.5. I dont have a detailed PH meter, i got the two rods you stick into the soil
Humidity: around 60%
Temperature: 75-85 degree F
Age: Maybe 1.5 months. Stupid me just started growing without marking the date and lost track....
Stage: Flowering
Fert: almost nothing - i have Fox Farm Big Grow, tiger Bloom and one other one. But i rarely use it.
Lighting: 4 - 42watt CFL 6500k (yea i know 2500k is better for flowering) - they are at least 8 inches away
Water source: TAP - with about 6.5 PH level
Light Cycle: 24 hour
no bugs - i have checked. Also in a 2 gallon pot (i think 2 gallon). But the plant is only 6 inches as is anyways.

Symptoms:Older leaf tips are turning brown at an alarming rate. The brown is REALLY dry - crumbly dry. The green leaves are somewhat dry feeling as well - but by no means crumbly. The effected leaves are curling under a bit, but not bad. I did notice some viens are getting lighter green than the rest of the plant - this is new. Happened today - after the flush yesterday.

The story...

So it was doing BEAUTIFULLY! All green - used some Fox Farm fert in the beginning, got PERFECT lol No burns, no light green, not to dark. Simply beautiful. So i took my PH meter and it was around 8, so i figured i would dilute some vinegar in some water and feed it to lower some PH. Bad idea - **note to self...dont do that again**. After that it the older leaves started to get brown at the end and REALLY SUPER DUPER dry. the pointy end of the leaf would crumble if you touched it. It pretty aggressive.

I have since then - yesterday - flushed the shit out of the poor little baby. I must have put 10-15 gallons of water thru the soil. The buds are looking fine - not a single deformity, but the leaves are just going fast! I realize when its flowering, it will turn the leaves a bit yellow but this is not that...

i trimmed some fan leaves that was blocking the light to some bud spots - so she looks a bit funky. I think the lesson here - is to leave your plant the FUCK alone until it actually does need something. it was doing great before i got some 'brilliant' ideas...

im trying to add photo's...lets see how i do


PS: For some reason i had to use about 100 br HTML code tags to get this damn post to format correctly. If i dont use them my post is one big messed up paragraph. Am i doing something wrong here?!

Here are those pictures. Shes a small-one. This is with my cam phone so - they prob look shitty as hell

damn all the work to get the post formatted correctly yet no replies...

looks a little burnt how much you feeding and when was the last feeding. you should cut out the Nitrogen and boost your P and K aswell calcium and mag, and when i say burnt i mostly mean to green,her leaves are very green for that late into flower.

the last time i fert was about 1 week ago - maybe a week and a day. Im not sure about the PPM - but it was almost nothing. I put about 1/4 strength of what the website says (fox farm). I think what burned it most was the vinegar to lower the PH...i really wish i never did that.

Since i already flushed it out with tons of normal water...did i do the correct solution to fix this issue? And since its burned - would it be alright to actuallly feed it some tiger bloom (has TINY bit of N).

shit ill just keep fuckin with it i guess until i get it right.

you overferted it?

judging from the pictures it looks almost done. am i right? in that case nothing to worry about, i guess.

i just looked at the trichomes tonight - still crystal clear. Its looking a bit better today after i flushed - the leaves that were burnt are getting worse but not as aggressive.
