3/8 plants seem to have ca mg def but not sure

i have some curling tips pointing upward and brown spots on the edges and the leaves feel like paper and they would probably crumble to the touch 3 out of 8 plants to be exact

i cant wait to finish this soil grow ...last time with soil for a while..Im sick of the inconsistence of soil .. i have all the equipment to run 6 4x4 flood trays and 6k lights cant wait ..i have 8 mothers getting ready for my next op..

i have also noticed slightly redish stems on a couple plants normal or def.ive read that this is normal on some strains

What was the establishing technique? (seed or clone?) seed
What is the age of your plants? seeds popped out of soil on 12-14-10

How long have they been in the soil mixture they are in now? 1 week before flowering

Were they in the same mixture when they were seedlings/smaller plant? If not, what mixture were they in before? seeds started in FFLW untill roots took hold then taken to 1 gallon pots with FFOF . then on 1-15-11 i transplanted to 3 gallon to finish out in 1 week for stress recov before i put into flowering

What PHASE (seedling, vegetative or flower) are the plants in? flowering 29 days in 12/12

What Technique are you using? (SOG, SCROG etc) el naturale with a small pruning at the bottom for air circulation went up about 3 nodes up from bottom

What size pots are you using? (Include how many subjects to pot) 1 plant per 3 gallon pot

What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?) FFOF

What brand Nutrient's are you using? FF grow big-- big bloom --
tiger bloom--- CaMg+ i have Gravity and snow storm unltra but havent used any yet at all

How much of each nutrient are you using with how much water? *Knowing the brand is very helpful* i didnt use Grow big at all during veg...which im kicking myself in the ass for now ..I wasnt able to build a tolerance up for nutes before flower stupid mistake but wont happen again only used big bloom at veg time 6 TSP gallon

How often are you feeding? FF feeding schedule every other watering

If flowering, when did you switch over to using Bloom nutrients? 2nd day of 12/12

What is the TDS/EC/PPM of your nutrients used? 1.0 ec

What is the pH of the "RUN-OFF"? when i did a flush on 1-26 run off was 6.5 ph of water fed to plant was 7.0-7.1...i havent done a soil runoff lately but i will do this on my next watering which is on 2-22 if they need it

How often are you testing pH/ppm/EC/TDS? i test ph every watering 6.5 everytime and i test Ec everytime also and i also calibrate my ph pen everytime to

What method of pH test was administered? Using Strips? pH pen? digi pen

How often are you watering? when pots are light

When was your last feeding and how often are you feeding? as directed by FF feeding schedule trying to build up to proper nut strength since i didnt feed any nutes in veg state im up to 8 1/2 tsp of TB and 12tsp of BB and 8 1/2 tsp of grow big ...Feeding with nutes ever other watering

What size bulb are you using? 1000 watt digi hps aircooled hoods

How old is your bulbs?only been run for 2 flowering cycles

What is the distance to the canopy?18-20 inches from middle plant maybe 15 inches on edge of tray

What is the current Air Flow? (cfm etc.) a huge 8 in vortex fan

Tell us about your ventilation, intake exhaust and when its running and not running ?8 in vortex vented through 1 hood i have 2 hoods but that side of flowering is a month behing this one ..speed controler fan is sometimes on when lights out to balance the heat

Is the fan blowing directly at plants?nope just over the top of them it moves the leaves every pass though and one pointed down near the pots for aircirculation

Is the grow substrate constantly wet or moist?i dont think it is i dont have a moisture meter but when lifted they are light in weight i usually dig down with my finger about 2 inches down and if dry they get watered..from the looks of things its pretty much every other day

Is your water HARD or SOFT?not sure i think soft well water i dont have salt build up or calcium build up . clay in the well water that is in the groud and it is visible some what if it sits in a container...i have recently flush my water system..preasure tank all of my in house pipes and my water heater ...no more clay build up when water sits in container did this on 2-18

What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water? well

Has plant been recently pruned, cloned or pinched?cut 3 -4 nodes from bottom for aircirculation on the 2nd week of 12/12

Have any pest chemicals been used? If so what and when?never seen a bug besides a couple black flies but never more than i can count on 1 hand

Are plant's infected with pest's?i hope not if so im fucking blind


i do also have a line of nutes that i havent used yet which is

AN sensi grow and bloom A&B for dro after this last soil grow
Chaching resin production probably wont use this run
Gravity bud hardener
Bushmaster for the ones that try to get outta control in stretch
snow storm ultra more trichome production ganna use this along with gravity
after doing some research after seeing this problem over night im under the conclusion that it is a Ca/Mg def . im going to start watering with a ph of 6.7 -6.8 which i found out that Ca/Mg def and get lock out below 6.4 but i want other opinions on this

i can take more pics if anyone needs them

bump bump bump

Dude I have this exact shit. I cant find anything even remotely mentioning what this is. Some people say it's your ph some people say your plant is root bound. Some think it's calmag or molybdenum. Idk man. Tell me what your finding are..... Positive energy to your plants.

It looks like it could be heavy metals in your well water. Why did it take so long to establish - It took it a while to build up in the soil. With the transplants, you kept adding fresh soil. That is my 2 pennies. Good luck. You will probably lose those fan leave on the 3 affected plants.

How do I clear em out?

I don't have much personal experience with well water except for drinking it up at the family cottage as a youngster. You can probably get your water tested for not too much money and then formulate a corrective action. As for right now, I would pour 3x the volume of the container of purified water to try and flush out the bad stuff.

i dont think its my well water i did 2 grows before this on the same well ....tds meter reads below 100 on the .5 scale and i didnt have this problem last grow the only diffrense on this grow is i have diffrent strains ran bag seed last 2 grows and they were champs but had a high count of hermies but always got ride of them ....

you can use clearex thats what i have havent used it yet though havent had the need yet .....but im not so sure its my well ...Do you have well water ?

Looks like heat burn. Get another fan
See how its the top leaves. Lot of people grow with well water and dont have this problem.
If you can drink the water then they can.
Cal defs are not likly in soil. Unless your ro'ing your water..

I don't but I use tap water. It's at 331ppm

it maybe temps but i do have a thermo that hangs down from the hood and it never goes above 80... most of the time the room temp is at 72 and the canopy is at 75-77
i do have some leaves towards the middle that are doing the same thing i can take better pics if u want

do you have a stand up fan??

We might have to call in the big dogs. Where's fdd2blk when you need him.
Or potroast

P lockout most likely caused by a Cal imbalance

most folks will say cal/mag because FFOF is notorious for it

two things, you really feed 6 tsp of nutes per gallon? if I did that with my nutes my plants would be dead in hours LOL

and FFOF is a hot soil you did not need to feed nutes for a minimum of a month after your last upcan adding nutes would make the soil way hot

and a note you should wait 3 or 4 weeks after an upcan before flipping to flower as you want to give the roots time to dig into the new soil, root production slows drastically once in flower and you are a) wasting soil and b) asking for watering issues

is your well water filtered and if so how? most folks are unaware that the cal total needs to be equal the the sodium total in your water with a ppm of 100 I doubt there is a lot of sodium?

What di you know about smooth edges? Like non serrated leaves

um i dont feed 6 tsp of nutes i feed about 8 1/2 tsp of tiger bloom and 8 1/2 tsp of grow big and 12tsp of big bloom and 5 tsp of camg+ to 5 gallons of water ec reads at 1.0 ..i only feed grow big around 4th week of flowering and the beginning of the 5th week..well water is not filtered at all ...if u read with the info provided i watered with plain 6.5 phd water and the next morning this happened.... when i fed with all the nutes listed above was on 2-15 then i watered on the 18th with plain phd water and then i walked into the room on the following day and boom out of the blue.i will take advice to clear this anyday i have a whole list of nutes i could feed them with but i usually keep it simple .....i used this well water with 2 other grows and never had this problem ...
..but this is a new strain 1st time running it ...my first 2 grows went of with a bang then i get away from the bag seed and get seeds from Nirvana and boom now i have problems ...im in no such way saying anything bad about nirvana but hell my bag seed was 10x better than these ...... on top of that i never phd my water for those 2 grows then i start ph'n on this grow and nothing but headaches....going hydro cant take soil anymore...i would love to clear this up it hasnt gotten any worse after feeding camg+ but who knows this may have not even been the problem....after this harvest R/o machine for the dro setup cant wait...the only problem i see in the future about not needing to feed them anything when u transplant is when u go into flower they have no tolerance for synthetic nutes so then u have to start at the bottom of the feeding chart so u dont burn ur girls


if u have questions that could help me clear this problem up ...ill give detailed info ...i just have to look into my journal and see....

I'm pretty sure I'm dealing with the early stages of this. Growing in a super soil and idk what's in it... Got it from a dispensary near my house. I've been told calmag but my top leaves are looking like phosphorus lockout.. Idk what do you think?

here's the pics

Try NO nutes ! Flush with the WELL water, use well water and nothing else except maybe molasses and guano.

It might be a PH problem. What is the PH of your sol. going in and what is the PH of the runoff?

Even if it is or isnt a PH problem I think your best bet would be a good flush. You can use just water if you wish but then there is a chance that you will wash away all the nutes out of your soil, then what happens is your plant is still dying but now from hunger. I recently had a PH problem with my plants i flushed once with water and then again with a very dilluted calmag/nute solution now my plants are doing fine. I also use FFOF and FF nutes.
