GARLIN Posted May 29, 2019 Share Posted May 29, 2019 Hi All, This my first grow and sort of found my through it by reading online and asking questions. I've recently experienced that my plants leaves are getting spots then turning yellow and eventually just falling off. Look at the pic and advise if anyone can. Is it a pest or calcium deficiency ? 1 Quote Link to comment Share on other sites More sharing options...
greenkush Posted May 29, 2019 Share Posted May 29, 2019 Deficiency, possibly nitrogen. 1 Quote Link to comment Share on other sites More sharing options...
JrMezz Posted May 29, 2019 Share Posted May 29, 2019 Hey bro Any other info on the grow ? Looks like a deficiency for sure Quote Link to comment Share on other sites More sharing options...
GARLIN Posted May 29, 2019 Author Share Posted May 29, 2019 Its close to switching over to flower and have noticed this since Sunday. The plants are all growing in soil , organic promix , I make sure the ph of my water is right all the time. Plants are under 2 x 300w cfl dual spectrum lights which i bought from futurama . I monitor the environment as well. Its been a bit cold these last few days so I added a 300 hps light just get the temp up in the room... Thats about it Quote Link to comment Share on other sites More sharing options...
JrMezz Posted May 29, 2019 Share Posted May 29, 2019 IMO id say it needs some cal mag and maybe some N like @greenkush was saying As you go into flower though you going to want to lower the N and increase P and K 1 Quote Link to comment Share on other sites More sharing options...

CG420za Posted May 29, 2019 Share Posted May 29, 2019 Spotting and yellow leaves could be magnesium def, especially of you finding it on the lower leaves. It's a mobile nutrient, so the new growth pulls it up from the older leaves if it's lacking or locked out in the medium. Reset with a flush and take it from there. 2 1 Quote Link to comment Share on other sites More sharing options...
JrMezz Posted May 29, 2019 Share Posted May 29, 2019 Agree 100% with @CG420za Flush through with a decent base nutrient and see how she does Quote Link to comment Share on other sites More sharing options...
SkunkPharm Posted May 29, 2019 Share Posted May 29, 2019 What brand of soil? Promix sounds like a Coco coir based mix Sent from my VTR-L09 using Tapatalk Quote Link to comment Share on other sites More sharing options...

GARLIN Posted May 29, 2019 Author Share Posted May 29, 2019 That is the soil .... https://hydroponic.co.za/hydroponics/promix-organic/ Quote Link to comment Share on other sites More sharing options...
Green Leaf Organics Posted May 29, 2019 Share Posted May 29, 2019 (edited) Did you spray that plant with anything recently? Looks like burn to me Edited May 29, 2019 by Green Leaf Organics Quote Link to comment Share on other sites More sharing options...
SkunkPharm Posted May 29, 2019 Share Posted May 29, 2019 That is the soil .... https://hydroponic.co.za/hydroponics/promix-organic/This is an hydroponic based grow medium. It contains about enough nutrients for 2-6 weeks depending on the size of the plant. It says organic because it is amended with some organic Nutrients. But it is not. You will have to feed salts.Sent from my VTR-L09 using Tapatalk Quote Link to comment Share on other sites More sharing options...

GARLIN Posted May 29, 2019 Author Share Posted May 29, 2019 No i havent sprayed it ... Quote Link to comment Share on other sites More sharing options...
Green Leaf Organics Posted May 29, 2019 Share Posted May 29, 2019 (edited) I personally dont think that is a deficiency but like @CG420za said a flush would be your best place to start. Looks like burn or root damage to me ....just my 2 cents Edited May 29, 2019 by Green Leaf Organics Quote Link to comment Share on other sites More sharing options...
SkunkPharm Posted May 29, 2019 Share Posted May 29, 2019 For me it looks like nutrient lockout due to pH imbalance. Sent from my VTR-L09 using Tapatalk Quote Link to comment Share on other sites More sharing options...
420SA Posted May 29, 2019 Share Posted May 29, 2019 @GARLIN has this literally crept up in a few days. How long have these signs been showing? Quote Link to comment Share on other sites More sharing options...
GARLIN Posted May 29, 2019 Author Share Posted May 29, 2019 yes it has the 5 to 6 days at most I would say .... Im not in there daily because of my work schedule so I cant exactly say Quote Link to comment Share on other sites More sharing options...
