Need help/advice on flowering church under CFLs

Hi advice needed on a problem iv got on one of my plants please.

Strains is The Church
Soils medium is compost/perlite.
Feed is bio fish mix, bio grow and bio bloom
Veg for 3 weeks.
Been flowering for about 3 weeks.
108w cfl lighting.
Noticed problem a few days ago.

Now, iv bent the plant over so its all on a pretty even level regarding the canopy so theres no top and bottom of the plant just left and right! The problems is affecting what would be the bottom of the plant near the soil. The very end of the leafs are turning brown and dieing, and their curling under. It seems to affect the small fan leaves close to the bud sites. And it is starting to appear higher up the plant around the bud areas.

I have no idea what it is, iv looked up sick plants and cant get a definite answere. Please take a look at the pics:

 
Possible signs of overwatering/root damage. Your soil looks very wet in the second pic, what kind of mix do you have?

edit: I see that it is compost/perlite but it seems clumpy and looks like it doesn't drain well. How often do you water?

Not over watering. I let it dry out then i water it. Every 4-5 days atm.

Compost and perlite mix is very clump free. I thouight it looked like a defficiency?

What ratio of perlite to compost do you have? I kind of agree with the above poster. The soil looks like it might not drain well and depending on the cab conditions (temp/moving air) it would certainly still be possible to over water even if you were only watering once every 4 days. Do the lift and tilt test to check when to water.

If that isn't the case however, I suppose it sort of looks like late stage P deficiency but it seems like you have your ferts covered...Can you be more specific about your fert/water schedule?

Cheers ratio is 40/60 perlite/comp.

I have another plant same strain, same ratio and it was fine all the way until i over fed it, but until then no probs!? I had just watered it aswel tbh..

Some leaves are slightly yellowing but i think that N defficiet with it flowering..

Well that soil should certainly provide enough drainage... I doubt its an N deficiency. Wish I could help more =/

Hey man. Sorry about your plants. Looks like a Potassium deficiency, with the edges curling down and such. Could be a P & K deficiency.

Does your soil mix contain lime? What is your runoff pH? Have you ever grown in the mix you're using now?

Check out this thread.

Cheers man i think your right about the P and K, but possibly not a deficiency, maybe an overdose on t he bio bloom??? I dont know, but i know after i fed with plenty of bloom and grow it didnt get any better.

No lime in the soil at all, iv got some though think its worse sprinkling a bit on the soil?

Not a full grow to bloom, everything was fine in veg just now 3 weeks into flower its happening.

I havnt checked the PH yet will do after this.

Thanks Skunky

The PH is 6.7 and i have already seen that thread on sick plants but couldnt be 100% sure it matches anything. Il look again now that hte problems seems to be worse than ever.

C'mon people someone must have had this problem before. The plants just sat here dieing off slowly and im fuckin sat here like a lemon not knowing if i should feed it or flush it!?

Fucks sake have some sympathy for the poor bugga lol!

It looks like you have more than just one issue going on to me.

I know you say you only water every 4-5 days, and I know your perlite to compost ratio should allow plenty of drainage, still I see signs of over-watering.
I also see a bit of a P & K deficiency.
But to be honest without knowing just how much nutes you have been feeding them it is really hard to diagnose whether it is a deficiency caused by not enough of something, or whether it is a deficiency caused by giving them too much of something, and having something locked out due to that.

You mention the nutes used, but do not list the N-P-K of each, it would help if you could do that, as well as let us know how much of each nute was used, for example (1tsp bio grow, 1 tsp bio bloom per gallon) etc...
By the looks of the size of the plant I doubt you were mixing the nutes up in a gallon of water, so if not then how much of each nute did you mix per pint, or quart?
Did you feed during every watering, or did you just give plain water on occasion?

Another question I have, what sized pot is that, a 6" or 10" pot?

You could possibly have a bit of a root bound problem, and possibly a bit of root-rot from over-watering.

Could you carefully remove the plant from the pot, and get us a picture of the roots?

Do not worry about stressing the plant, as long as you are fairly careful you are not going to do any damage to them.
I have transplanted before when in flowering, and noticed the roots were getting a little root-bound, so I trimmed a little bit of the roots off, and the plant did not show any signs of being stressed from it, just don't try to reduce the root mass all at once, if it is root-bound you could shave like 1/2 inch off of them all around, but try not to shave off more than that...

An alternative to shaving a root-bound plant would be to ruff them up a bit with your fingers, that way when you transplant into a bigger pot the feeder roots will expand into the new soil properly...

Cheers mate.

Id say your spot on with the response!

I cant say how much fert exactly i used, after my 1st grow i got a bit 'clever' i think, and now i dont measure and just pour in what i think! It was equal amounts of bloom and grow ( bloom is 2-6-3.5 NPK and grow is 8-2-6) i poured 4ml of each roughly into a litre of water and gave the plant half of that litre. I feed every other watering.

I also flushed it about 4-5 days ago and gave a light feed (1ml of each, bloom and grow). Dont know what else i can do but wait and see how it goes, hasnt got any better since i flush and fed!

I gave it a good feed because the leaves were looking a bit yellow and was showing a N defficiency. But the yellowing didnt get any better and the leaves started curling under..

Pots are 6" round, and im certain their not root bound, i grew my last with pretty much same components and it was great. A couple of roots are visible from the holes in the bottom of the pot and they are a nice white colour, not unhealthy... so i think their good.

Would you say it was N defiviency and possibly then an OVER feed and burn? New growth is still shooting up also, but the older leaves show the symtoms.

Il check the roots anyway when lights are back on to make sure.

Thanks for the very helpful response dude ;)

Just to say the plant is getting fucking worse im so pissed off.

Buds are not growing like they did on my last grow, im doiong something wrong but my stoned head cant figure out what. im getting angry watching her slowly fucking die away what i waste of 3 months.

Weeks ago i checked the roots, fine. I flushed and left for a week then fed light dose of bio bloom and fish mix.

Then i started on the bigger dose of 3ml per litre each of bloom and fish mix.

It looks like a defficiency of phosphorous and nitrogen to me but im no expert and it keeps getting worse.

Its got under 3 weeks left, which is when it normally adds weight, can anybody help me to fill her out. Should i be feeding 5ml each grow and bloom?

Here she is now-




THANKS
