We are trying to duplicate Nature ,where in Nature do you see ever green trees un less there ferns of some sort.All leaves turn yellow Come Fall ,Autumn.If its not been too windy these become crispy and then the wind blows them off or they fall off .then become Mulch for next seasons trees food ,The worms and other insect life break it down into feed for the start of spring.The last thing i want is too much Nitrogen and chlorophyll left in the plant .The sugar leaf is cut from the plants during pruning and i beat it to get sift for hash making,The Chlorophyll left in any bud i process into Oil ,Can be got rid of by after soaking in Alcohol just leaving it in a warm sunny place,I have done hours of studies into this and this works best.Honest Guys your Reading into this has though its caused via heat or nutes it not ,it caused through the spidermites and thrips that was on the leaf and the age,The age mainly towards end.The bud is Looking super nice ,Once Pruned up it will look sound very nice in fact.Its covered in Good Quality heads that are Milky in color now,I would rather pick it a little early than late,because there is more likely to higher amounts of cbd in it,after 10 week not sure they will be any in it.It also taste far nicer early than it does over done,it all ways seems to be sweeter,Pineapple Express at 8 week is one of the nicest tasting strains i have had.And like i said earlier,in a post.The only reason they look that burnt is i did not want to remove anything till i really needed to.Just in case any of the mites or thrips found there way to the new plants i have vegging.I am treating them ,atm just in case.
