problems at the bottom of the plant.

Hi i have attached some pictures to see if you can try help me out with this issue, i grow in soil and use canna, ive been growing for 3 years and never had this issue before and never used a ph or ec tester. i always use the same brand soils etc, The issue seems to be with the clones which are blue/cheese, i have planted a super silver haze and blz from seed and they seem to be perfect, i originally thought it was some kind of deficiency so i bought some formulex and added it to my feed. this issue is only affecting the bottom leaf of the plants. thank you

Might just be a hangover from the cloning process. New growth looks good. I would just monitor to see if it is spreading or not. I imagine they will be just fine.

these have be planted for about 2 weeks and it seems to have just started.

have u been feeding nutes looks like a nitro issue..almost all the tips are drying and pointing straight down

hi yes i have been feeding nutes. and the lights were off for a good hour when pictures taken.

wats your ph..may have nute lock going on

I dont no ive just ordered a bluelab ph/ec tester today i have never needed one before as i only ever used the canna all the way through with no booster or pk's or owt, ive always done really well but this problem as come out of no where.

Hmm.....Blue cheese has been a kinda fussy plant from time to time in my garden....

At this point it doesn't appear to be big problem.

Veg or bloom nutes?

Don't start bloom feeds till week 3 after the flip to 12/12.

Do you add a Ca/Mg? Looks like you might start with this one...

What lighting?

Doc

Thank you Dr. who for the reply much appreciated, Im on veg and use canna and I've started to put in formulex as it contains a full nutrient profile in a single container. ive attached the picture so you can see, i go to 4 weeks veg before i flip to 12/12.
.

Do you spray for spider mites on a regular basis?and how much nutes you using here?

no ive never had spider mite at all and never used any spray to spray the plants, ive used exact same ratio nutes for last 3 years of growing, ive orered a bluelab ph/ec tester so ill check them when it arrives.

OK,,be SURE to keep in mind that the Formulex is 2.3 - .9 - 3.4 NPK value!

If you use both the Canna and the formulex at the same time. You need to adjust the amount of Canna down a bit..

Doc

In reality, The Canna really doesn't need the formulex....The Canna line is complete.

ok thank you very much ill keep a eye on them and ill check the food once mixed with a ph/ec meter to make sure everything is ok. cheers
