yellow leafs

Ya 2 of my plants are getting yellow fan leafs idk if this is because they are getting ready to bud or what but they only yellow on the big fan leafs theres also alittle bit of brown on the tips of the leafs. im feeding them grow big every 3 days 1 tsp for each gallon is it from nut burn?

Not much of a nute burn if its only a lil bit of a tip of the leaves. If you've switch to 12/12 for over 1week it is normal But the yellow shouldnt be progressively. Is it yellow from the bottom? if so its normal for flowering stage.

possible nute burn, but my plant is in the 3rd -4th week of flowering and her big fan leaves are doing the same thing, i've had this happen before. It seems to be pretty normal when they start flowering, but i'm using fox farms big bloom and tiger bloom, no overferting here, can tell cause my plant is a beautiful green on all the leaves except the oldest fan leaves which are yellowing. maybe reduce the ratio and frequency of your feedings. goodluck with the grow!

not really yellow on the bottom just the bigger fan leafs are turning completely yellow also there are small yellow spidders what are those udner the leafs?

if the yellowing persist and spreads give her a lil nitrogen,,,,,if only the very tips of a couple leaves are burned then no not nute burn but if it looks like all leaves are burned bad then yes,,,,theres no pics so its kinda difficult to analyze the situation

thanks andyk

so i can just buy nitrogen at any hardware store is it in a liguid state?

those are probably aphids....get neem oil

will they hurt my plant
