pain in the ass noob problem

first timer in my sixth week of flowering. I've run into a few problems but for the most part its been smooth Ive spent alot of time on RIU trying to gain as much knowledge as possible but I still have many questions..MY PROBLEM RIGHT NOW.. is these spots ...one plant developed them early in veg but the problem subsided. Yellow spots that turned black once the ph was corrected. now i'm in the home stretch and here's what i have on one of my favs i fim'





fucked up the resizing ... the middle pic is what im trying to explain ...this has made it all the way up to the leaf around the cola. ANY IDEAS???

too blury, try again....

kinda looks like a mag. def. to me

2nd vote for Mag def. I just went through a nice bought of this myself.

I was guessing mg def also but it also looks like K def also ...like i said it's my first grow so i cant be sure ....but it's scaring the shit out of me ...its a beautiful plant ...as soon as i figure how to resize on this computer i'll post more pics ..
ALSO noticed a thread posted a bit before me asking about mg def... his pics look much different.. but then again that's his question.... I was wondering about lights being too close ..I'm using cfls in happy frog with FF nutes... although i've been cutting back on the tiger bloom.. it's dropping my ph drastically.

a better pic ? if this works ill post more

looks like calcium deff to me , loook it up. if its helps alittle rep this way wouldnt go astray lol

i've read up on calcium def... but the symptoms don't read like calcium def .. what i think happend is lack of K made all the immobile nutes out of wack. so you may be partly right... i have to research more ... A LITTLE MORE INFO ABOUT MY PROB. i noticed this starting to happen after i switched some bulbs around. i replaced a clutster of 23 watt bulbs and threw a 65 watt in that day... when i came home .. i noticed the leaves then i looked at the plant next to it ...same spots under the same light. i thought it was mold or fungus at first but after scanning with a black light i ruled it out... this plant could also be rootbound if that may cause my problem....i don't fucking know man ... it's frustrating

ph fluctuations can also cause a problem like this .....rofl good luck

the ph has been a problem for a while now due to 8.0 water and personal errors... i have ph down .... I'm just SCARED .. you can see how close to the bud site the problem is....its a beautiful bud .... and it seems like it started from top down? .. do i clip early?????

Ya know, it very well could be calcium (better pics help a lot), either way just fix your pH ASAP and then give the plant some CalMag. That way no matter which one it is it will be taken care of.

why would you want to clip early?
its not even a big deal
just chill and figure it out, and even if you don't figure it out.. so what, grow that shit.
