Yo Peeps, Mary's beeing going strong until now.

Details:
Medium: Soil
Lights: 12/12 cycle with 4x 24w 2700k cfl and 1x 48w 3000k cfl
Stage: 4 weeks into flowering, and first sign of pistils
Ph: 6.5-7.2ish check pic provided.
Nutrients: Miracle grow all purpose 3/4 strength about every 2nd to 3rd watering

Problem:
Few of bottom fan leaves are all starting to turn a light yellow colour and some have brown spots on it.

Is this a nutrient deficiency ie: Nitrogen or is it just reaching mid way through flowering and the leaves are naturally turning the yellow colour ?

Any advice or opinion on how she is going would be appreciate :mrgreen:

i had that problem with spots. but use your search button n see how many people have this problem, when i searched no one really knew what was the cause. i flushed mine seemed to help but then came back on worse. one mom almost died till i put her outside got better deer eat it or something. the other mom died but got clones off of her second go around had it but then it cleared up. but when i flowed mine with the spots they cleared up, someone said it could of been a mag def or potash def because in my flower room i run hydro n give them a higher dose of magical n potash. but ne ways good luck

You have nutrient deficiencies so flushed all the available nutrients out. Way to go ace.

Nah i didnt have any deficiencies or anything, everything was quite green and looking swell actually :/ .....

If it ain't broke, dont fix it. I got a little carried away, and i wanted to start taking preventative steps lol.

She's been flushed a couple of times in the past but not in the past month. She got flushed because of a fungus gnat problem. Looking at ic guide it does look like calcium deficiency. What's the best way to solve this? I've read Epson salt or some garden lime will help right?
Pretty sure she is not overwatered as she gets watered maybe once a week if that

And garden lime would also solve a mag def as well right? Might be able to kill 2 birds with one stone lol..

Also how much longer do u think she has. Some of the pistils are turning a reddish colour now.

Yep, dolomite lime/garden lime helps with cal/mag and helps to buffer your ph so it stays consistent. Add 2 tablespoons per gallon.

quick question, how often should garden lime be used ? should it be used like other nutes so every 2nd 3rd watering or jsut once ?

No, top dress it. Before you ask, top dressing is when you just sprinkle it on top of the soil, then as you water it, it will get absorbed slowly. Top dress two tablespoons of lime for every gallon of soil. You should only have to do it once.
If your talking about Canna pk13/14 when I grew dwc last year I think I used it weeks 4,5 & 6. It's pretty vague directions, I think it said something like start using week 4 and stop when leaf tips start to burn WTF?!

Lime is a must but doesn't provide enough usually to keep the plant happy.. I would recommend getting some calmag also

Ok 5 tbsp of lime was used for a 3 gallon pot as it was not completely full with soil. Also 1tbsp was mixed to a quart of water and used to mist the foliage as according to icmag. really hope this solves the problem.

Now to decide whether to buy canna pk13 or a bloom boaster with npk ratio of approx 7-16-17. Any recommendations guys?
