Hungry or Burnt? (photos)

I also posted this in the Newbie central but I figured here is more appropriate. Copy pasting.

Hello 1st grow green-o-matic on a 6lt pot using biobizz light-mix soil with 210 true watts of cfl (2700K(105w) & 6400K(105w)). Temps are at 24-25 (a few weeks ago 27-28 celcius and humidity 44%-51%.

I'm 5 weeks from seed and around 2 weeks into flowering. I didn't start feeding until 2 weeks ago because she didn't seem to need it.

On to the problems now.

1) On the top part of the plant where the top bud basically is I've got some droopy leaves.

2)Got quite a few purple leaf stems.

3)Got a couple of yellow leaves on the bottom of the plant with some browning on the edges that looks like it's moving to upper leaves aswell.

Since it's an autoflowering strain I figured I shouldn't feed alot. About two weeks ago (3 weeks since seed) I added 0.5ml of biobbiz bio-grow and 0.6ml of biobizz bio-bloom in 1,5lt of water. On the next consecutive watering I added 0.5ml of grow and 0.8ml of bloom in 1,5lt of water.After that was plain water and on the last watering I added 1ml of biobloom to 1,5lt of water. I water every 4-5 days when the top layer of the soil is dry, and water till I see a bit of runoff. Plain water is around 7ph and with added nutes it's around 6.8ph (unfortunately I only have paper strip tests). Runoff is between 6-7ph.

Trying to figure out what's the problem before the next watering that is due in a few days.

Thanks in advance for any answers.

Well today morning I had to water since the top few inches were dry and I added both bloom and grow nutrients since the yellowing was climbing towards the top along with some brown spots on some fan leaves. I read up about deficiencies and it looks as if she doesn't have enough K & P along with a slight N def. I don't think that feeding her was a bad choice considering I have been more than "soft" with nutrients. If the feeding makes her look worst in the next few days next watering i'll a complete flush and start anew with nutrients. I'm hoping that won't be necessary though. Again thanks for your help and I'll let you know how this whole thing turns out in this thread as soon something changes.

2 Days later after watering..

I've got some spots on my leaves besides yellowing. Some are brown some are rusty. It's not all over (yet) but for example there are some spots on leaves on the bottom/middle/top. I took some photos to help a bit. Not the best quality but hope it does the trick.

Would really love some insight as to what might be going on so I know what to do.

Thanks once again.

P.S. First 4 pictures are before watering, rest are 2 days after.

Thanks for the fast reply.

I thought so aswell and I was told by another member here aswell just wanted to double check after the new development following the watering. Can anyone identify any specific deficiencies? Also forgot to mention I'm using Biobizz's grow&bloom. I've done 2 consecutive feed waterings but they have been very light (below 1/4). Can anyone suggest what I should feed next watering(keep in mind this is an autoflowering strain)? A friend of mine got me some molasses but unfortunately they are the sulphured ones. I thought maybe the plant could use the calcium and magnesium. Until I finally get ahold of the "right" kind of molasses though bloom and grow are my only feeds. Hopefully they are enough? It has been suggested to me that I get some epsom salts as well but i've read mixed opinions on using those.

If Yo checking Yo ph with strips so I doubt if yo checking yo ppms with a meter.
It's hard to tell what yo feeding or how many ppms~
oh ya yo looks like you need to feed some nutes!

Yep you're right there, no EC meter unfortunately. I'll boost up the nutes on the next watering. Thanks for your time.
