Away For A Few Days And ......Help Please!

Away for a few days and leaves are spotted on only about four top most larger/older leaves. Some are also curling downward/inward and are dry/brittle starting from leaf tips towards the the bottom only on the larger/older leaves. Have not used any fert., only FFOF from start and recent molasses every other watering; watering every 4-5 days(Due for and watered when I returned).

I have read some common articles/charts and think it might be a Phosphorus, Potassium, or Magnesium deficiency or a combination of all three.

Review My Pics Below - Thanks For Any Help!

Marijuana is not a regular plant it needs levels of all these elements at the. Vegetative stage of growth nitrogens/phosphate/solubale pothash/magnesium/molybdenum/calcium/ your plants need all these basic elements for simple growth in veg once you get these down start with molassus ect. Happy trails.

I did not see the bud pics duh well in that case u need levels of nitrogen/calcium/magnesium/phosphate/solublepothash/sulfur/and I add in some mycronzae also for good root health and added levels of pot hash at beggining of flowering and also elevated levels of magnesium ssulfate ans mollasus for flavor happy trails.

pick them off they will just shrivel and die anyway in a few days when they dry out. I have had that same thing and I just flushed the soil and started with a very low dose of nutes after it dried out, 4-5 days.
How much molasses are you using? You may have lockout nutrient uptake with too much sugar, but what do I know.
I say flush and dry it for 4-5 days and start with a low dose nute feeding.

WOW.
What is "Pothash"?
Maybe that's my problem as well.

Can you give pics of the whole plant?
How old are they?
Is this happening on the whole plant, or starting in a certain area and moving?
Lights?
Temps?

I've been using Grandma's Molasses at 2 Tablespoons per Gallon mixed very well every other watering. I water every 4-5 Days alternating between purified water and molasses water each time. I actually flushed lastnight as my first plan of action, just waiting it out for signs of improvement etc. I agree those leaves already damaged need to be trimmed off as their fate has been sealed. What nutes do you recommend with about 2 months or so of flowering left? I will be adjusting my molasses down to 1 Tablespoon per Gallon as well just in case.

Maxi-crop has soluble potash, i use it in my compost tea's. It has an npk of 1-0-4 with a guaranteed anaylsis of nitrogen 1.0% and soluble potash k2o 4.0%, it is wonderful stuff! If you use simple nute's op maybe i can interest you in a simple compost tea recipe? It incorporates everything the flowering ladies need to thrive.

I am hoping your using a peat based medium or along those lines here ya go sir!

Flowering nute tea mix:
2/3 cup Peruvian Seabird Guano
2/3 cup Earth Worm Castings
2/3 cup High P Guano (Indonesian or Jamaican)
5 tsp. Maxicrop 1-0-4 powdered kelp extract
(That makes the "dry mix". You can make all you want and save it to use later.)
Mix with water @ 2 cups of dry mix into 5 gallons of water to make the tea.
To that 5 gallons of tea add:
5 tbs. Liquid Karma
5 tbs. Black Strap Molasses
Use it to water with EVERY watering.

You can use queen size knee high nylon stockings for tea bags. 3 pair for a dollar at the dollar store. Tell 'em you use them for paint strainers. Put the recommended tea in the stocking, tie a loop knot in it and hang it in your tea bucket. The tea should look like a mud puddle. Agitate the bag in the water vigorously. An aquarium pump and air stone will dissolve oxygen into the solution and keep the good bacteria (microherd) alive and thriving. Let it bubble a day or two before you use it. If you find you are making too much tea and having to throw it out, use 2 1/2 gallons of water and cut the nute amount by half.

Soil: FFOF
Containers: BPA Free 5 Gallon Buckets
Water(purified)lants Watered Once Every 4-5 Days
Strains:Unknown x 3
(One is Tall, one is medium, one is short.)
Veg Period: 3 months with slight FIM/Topping throughout
Present Flowering Length: 50 Days
Temp/RH:70-80 F / RH 39-50%
Estimated Harvest: Early Spring
(2.0 - 2.5 months remain depending on how the strains are)
Lighting: 4 x 24" Flourescent Lights(Three Above Plants & One In A Corner Vertically) Additional lighting comes from 6 x CFL(100w Equiv.) lights placed all aroung the plants symetrically for even light and overall broader light spectrum. In the pics I have removed all CFLs from line of sight as they would obstruct pic POV. The top three Flourescents are raised only because one of the three strains stretched more (it was already massive from FIMing during veg) and needed the clearance. I already know for my next op I willl be adding about twice the lighting. Never the less, that's my current light setup.

Check out the photos I have added - I am having problems only with the largest and fullest plant
which is in it's own bucket. The pics below are from less than a week ago.
