Help

Im about 4 weeks into vegging and so far they have been coming along great. to make a long story short on a few leaves they are starting to turn light green..mainly at the top of the plant from both sides of the top of the leaf kinda at an angle it is a lighter green.... is this over fert.????????!!!!! Foxfarm soil and nutes..400W hps.. temp constant 79-86.. humidity constant 52-62%.. Should I just flush it real good? and give it straight
water for a week?

need help asap because when they arent good im not good.

haha that doesn't sound bad to me, but i'm not sure, i'm pretty new.

i think it might be the light heat is mayb affecting em? as long as they don't turn yellow n burnt n stuff, should be just fine!

or else, if its nute burn, i think the nutes wil lburn the lower leaves first before it hits the top. also, mayb the ph? not sure, still tryin to learn

I use distilled water.

Hey since no one gave any feedback I had some free time today finally and this is what I have came up with but it still doesnt fuckin satisfy me.
POTASSIUM (K) Affected plants are usually tallest and appear to be most vigorous. Necrotic spots form on lower leaves. Red stems. Leaves appear pale or yellow. Add chemical fertilizer containing K.


True to some extent. The plant showing the symptoms is and has been the biggest and most beautiful one in the bunch. However I DO NOT have red stems and most of the growth is healthy green. Its just at the top of my plant the leaves are a pale yellow...
