Issue with my plants

[Chucho]

1. Hello

Well I am probably in my 4th week of flowering stage and I first started noticing the discoloration at the beginning of the month of March, the first symptoms as you can see from an image started with a slight discoloration at the top of canopy in some areas of it, almost like in the middle of set up, I believed to be light burn since I am using for the first time a led light so what I did is I lowered the power through a dimmer to 65 - 70%. But I am not really sure , since I contacted the company who sold me the light and sent them some images and they could not pinpoint the issue. For this project I started with purple kush seeds , as substrate I used coco coir and every time I feed the plants I always control pH between 5.7 and 6.7. I am using as nutrients Dr. Jimz chicken soup for the soil and Bloom Kaboom for flowering stage. The dosage I am using wich was recommended by the seller product was 14cc chicken soup per 1 gallon of water during veg stage and when entering the flower stage was 14cc of chicken soup for the soil and 14cc Bloom kaboom together per 1 gallon. At to this point I have not been able to pinpoint the issue, since it could be something else. I need some assistance to be able to deal with it.

​​​​​​​Thanks a lot.

Looks like nute burn and lockout, the gold coloured plant is that a different strain?

Lower your pH to not more than 6 and cut nutes in half, seee what happens.

Quit feeding and flush that grow let it dry out flush it again let it dry out.........what's the bloom NPK i would not use anymore N do you understand? They are over fertilized. Best of luck you can save this grow it's just over fed be sure to allow the soil to dry not to the wilt stage. See what happens it sure won't hurt, i would do it.

You should never go with the manufacturers recommendations or you’ll overfeed your plants and cause issues like you’re having. Follow budgal’s advice then once you start feeding again go with 1/4 of their recommended dosage

Those leaves are way too green that’s nitrogen abundance for sure and if you have too much nitrogen you’re probably over feeding all the nutrients

Hey guys thanks a lot for your advice. I will do as you say.

I’m not aware of any nutrients made specifically for marijuana, otherwise I’d go by their recommendations and see how things go. Mary Jane doesn’t need much so she’s finicky. Apparently other flowers, fruits and vegetables need a much stronger dose of nutes and that’s what these fertilizers are made for

BBoy foxfarm recommendations work pretty good in my experience

BBoy there are dozens of liquid nutrients on the market for specific use for cannabis. Look again...

I agree. looks like nitrogen toxicity. Leave should be green yes but they look too dark. Having said that it could be the strain as purple kush has dark leaves but add to the the leaves at the top are dying I'd say toxicity. It's not your light. if it were, all the plants would look crispy on top the leaves would "canoe" and curl upward

 

[dilvish]

I would try to find better nutrients too. Those ones appear to be better suited to fruits and vegetables and flowers, but not the right kind of flowers...

 

[bboyfromwayback]

Dilvish, no need to look. I’ve always used FF with great results. I was only helping this person out

Are you saying you use their chart at full strength on marijuana with no issues? Their products are potent. Especially once you start adding Tiger Bloom. I’ve always ran their schedule at 1/2 strength from day 1. I tried full strength a long time ago and they looked like this grow.
