What is my best route out of this?
Up your feed too.In the short term, apply Epsom salts as a foliar feed in summer. Dilute the salts at a rate of 20g of Epsom salts per litre of water (1/3oz per pint) plus a few drops of liquid detergent. Apply two or three times at fortnightly intervals, spraying in dull weather to avoid leaf scorch.
nute burn nute burn... it is the prime point of pontification of the internet grow gurus... use my system or listen to my warnings and avoid the dreaded tip burn. 1/16 strength nutes are ok! Truth be told, a little bit of tip burn is perfectly natural and should be desired rather than avoided. Even in a totally organic grow where no nutes are ever applied, where everything the plant needs is in the soil and the microbes and the plants are taking care of all of the decisions... there is constant tip burn all through the grow. How can this be, that even growing naturally we experience tip burn??Ok Ive been worried about feeding too much as I thought I was noticing some nute burn on the leaf tips. Ill go for more though and see if the chlorotic effect gets better. And PH range 6.0 - 6.5 ??? Many thanks
