Any ideas on this one

[chomsky]

sorry, also they look like they require more nutrients, generally then you have been giving them (in addition to the extra magnesium).

(they look to have less N, then beginning pictures)

i would increase by 1/3 or something and see how they go.

--------------------

usually although i am in soil and use bio-b, it can take like 4 days or something to see the effect of the nutrients which is usually most obviously N,

like they don't have the abbility to miraculously heal necrosis or anuthing, but you should see general improvement after a few days.

nutrients also highly dependant on water amount of medium, plants can't eat without drinking, so make sure the coco doesn't dry out / is completely wetted throughout when watering etc.

(although not meaning to sound patronising etc, sorry if)

regards

Not patronising at all. I appreciate all the feedback. Thanks

Just when I thought it was smooth sailing I noticed this. I saw this at the top of one of my girls. I am almost a month into flower. This doesn't seem to be widespread but I don't want it to spread anymore. Any ideas whats going on here????
