What damage could this be?

deficiency or burn? in foxfarm ocean forest 5 gallon smart pots week 5 of flower advance nutes been feeding 1/4 to 1/2 dose with calmag ppms aren't too high really below 1000 all ph runoff has been about 6.5 always water with 6.8 water last watering flushed with 5 gals each with florakleen about a week and a half ago not sure what to do honestly should I reflush but this time use 15 gallons each or no flush at all or what? any help would be appreciated

why would you flush them if you werent feeding heavily? wouldnt that just wash away what nutrients were in there?

Looks like calcium def going on in there, probably Mg as well as potassium maybe some phosphorus....

They need the most nutrients when flowering. Up the cal-mag for sure. FFOF always seems to lose its Ca leading to deficiency as well as the soils ability to buffer acids. If youre water is soft, you can run into some serious issues calcium issues during flowering.

I would up the nutrients as well. Always add cal-mag first, then nutes.

I use reverse osmosis water I add calmag from botanicare 5ml per gallon advance nutes conno a+b big bud bud candy got some overdrive and b52 to add now so ur saying I should give them a full dose of advance nutes I gave them around a 1/2 dose last watering and the ppm of the water was 700 runoff was around that or so should I water them with 1 gallon or 2 each I just switched over to 2 gallons last watering not sure oh and I flushed while back cause I was told I had nuked them with nutes

Hey just a thought what are the NPk values of the nutes that you are using? This will say a lot. Good luck

Im using connosuier A+B with some of the additives so should I give them a full strength dose of nutes and see what happens

I mean the NPk values on those nutes don't know the brand. It's the 1-1-1 values. They will be labeled on the bottle. Just seems like maybe your nutes have to much of something. So that's why need the NPk values to see what your feeding them.

Conno A 3-0-0 Conno B 2-4-10 Big bud 0-1-3 Bud candy 0-0-1 Cal mag 2-0-0 never fed over 1/2 dose

Thats what i was thinking. To me that is to much to be feeding them especially for how young they are. Also those nutes don't seem to have enough N to support foliage. You want to support leaf growth to the fullest at this time so some nutes with a good amount of N is want you want. I myself use FFOF with good success with nutes that are a 3-1-2 for veg and a 1-3-2 for flower. A good product is dyno gro the 9-3-6 is great for veg. Also jacks has some great products you should check out. I don't think you need to be adding any "bud candy" or any cannabis specific nutes for that matter since none seems to support enough N and the prices are way to high. There are some great articles on here about this specifically some by Uncle Ben. This is a great article you should check out about nutes http://www.totalgro.com/concepts.htm Got this from him as well. Hope this helps Good luck

so then I should probably flush or just no nutes this watering

if my plants looked like that ,would make me think i gave them either someting they dont like or too much of something.

im thinking its too much potassium so do you think some florakleen would help flush excess

i would go ahead and give them a good flush then next watering give them a good feeding of a balanced food.I would give them something with a good amount of N. Dont be scared to use "veg" nutes in flower. Something along the lines of what i was talking about earlier. Also go ahead and pop them out of the pot and take a look at the roots, make sure it looks good. How they are looking will tell you more about whats going on as well. Thats what i would do at least. About the florakeen seems like a final flush? I personally have not used these nor have read anything that it would provide any major benefit but like i said have not used that product. Usually a flush with water will do. Hope it helps Good luck.

Charts like this are posted on the web.

I think what im gonna do is give another water with nutes just to see if it is too much or if it is a lack of cause i just took a look at one of my plants that i have been flushing for a week or so and its starting to get the fading green to yellow leaves kinda like the ones in the pics after this watering i will water with plain water with florakleen and calmag
