Hey guys,

sorry i dont have any pics yet but here is whats going on(2 weeks into flowering):

1) on some of my plants, the bottom fan leaves(moving up) are slowly turning yellow from the inner parts outwards. the veins seem to still be green tho but they slowly turn all yellow and fall off

2) this is problably nutrient burn, some plants some of the bottom fan leaves have dried up tips moving inward on the leaf.

im just wondering what the best way to correct these 2 issues?

Why flush when he may need to get more Nitrogen into his plant or plants . Pics help as anyone and everyone can say this and say that but @ the end of the day its like asking a Blind man if he saw the pot hole he just fell down lol.
More info helps like your nutriants , growing medium , Lighting , we want to know the lot , Temps , Humidity

because he described and said in number two he has nute burn, that's why. he's better off flushing and starting over with diluted nutes which will correct any deficiencies he has as well.

you have a cal/mag deficiency, you can spot the cal deficiency form the little spots forming and mag def from the way the leaves are going yellow with green veins, it is not nitrogen def, it looks similar but the veins dont stay that green while the rest is yellow.
whats ur ph at? could be a lock out, get sum cal/mag and get ur ph on track
happy growing :)

if you are 100% that you dont have bugs tho, those spots could be made form bugs =/ shoulda asked this b4 posting above info
and sum info for previous posters i know there are leaves that appear to be 100% yellow but that is simply the later stages of mag def

Better pics = better advice and agree with conepuller . If were Nitrogen def the leafs would still look and feel good but they would be yellow , as in your case thet look dry and crispy . To fix use TABLE spoon Epsom salts to gallon water = 4.5 ltrs , and give that plant a stack of water .
Fuck me ive been in from work now for 4 hours and ive only had one spliff , must roll one now .
Just forgot to give you this little info . Magnesium and Nitrogen defficiencies are hard to tell apart but heres a lil pointer..
on older leaves(fans) or from the bottom up
Mg deff. starts at the tips of the leaf then takes over.
N deff. start on the whole leaf,,,not just the tips

You can get Epsom salts from your local chemist , and just looking @ your plants they look dry / crispy .
To be honest with you , you may have bit nute burm going on aswll , just give Epsom salts and water for a couple weeks , remember cannabis is a weed , they can live and grow well without any added nutes , When i said a stack of water i ment use a gallon water , Wont hurt your plant

No need for the salts once you have given them once , just carry on with plain PH`D water .
Those dammaged leafs wont recover so keep an eye on new growth , That rep star is just in bottom left corner lol

they are in 3rd week of bloom so just to summarize:
give epsom salt asap, give 1 gal of solution to each affected plant? or all plants
- after the dose carry on with water for a couple weeks and nutriate again then?

just pressed rep start for you lol
