Im assuming this is lack of manganese or zinc, they are in dwc buckets and are being feed with ionic grow, they where all started at the same time and my biggest is 10" and smallest is 5" the smallest is showing the deficiency the most, whats the easiest way to solve it? they arent being over fed, it seems to only be affecting the new growth at the top of the plant as all the rest is looking real nice and growing good? whats the best product to solve these deficiencies?
double check your diagnosis using the links below. if it is mag, then 1 tsp epsom salts per 1 gallon water should fix it. dunno about zinc though.

ok, i mis-read manganese for magnesium so that makes previous advice about epsom salts a bit irrelevant. sorry m8 :)
its either mn fe or zn can anyone suggest anything that is high in these but not n p or k?
does ionic have all these in i just dont get it i mix it up properly and i get a nutrient deficiency my ph is 5.8 i lowered the mix incase it was a overfert but hasnt caused the problem to stop im currently only using 50ml per 20litres but may increase it a bit incase thats the reason the problem isnt getting any better the problem i have is i have some smaller stunted plants at 5" and some bigger 10" plants now which ones do i mix the feed for they are 3 weeks old all of them and now are all showing signs of deficiency.
cheers
anyone?
My local nursery sells a trace element mix. Do you have some pics?
