So Im a first time grower. Im in day 38 of flowering. The tips of my plants leaves are browing/yellowing up and some leaves are even getting these browing yellowing spots, is this normal because im getting twoards the end. Or is this a nute def, and I need to give some nutes to my plants? Shitty pics below hope it helps. Thanks for the time with any answers.

looks similar to this, are you using tap water or MG soil?

It might be the beginning of interveinal chlorosis. Here is a guide that helped me with a mg problem.

Here is a google image search of interveinal chlorosis...

If it is a nutrient problem then the next step to diagnosis is to determine if it is a mobile or immobile nutrient that is deficient. Is the symptom starting from new growth (immobile) or old growth (mobile)? This will narrow down your problem.

If it is happening everywhere then i would look at the bottom of your leaves with a magnifying glass and look for mites. Would also do the same if it progresses and the leaf veins don't become more pronounced b/c the area between is dying.

Hope this helped. At least it is a starting point, eh.

Go to Radio Shack and ask for a pocket magnifier. They're like $15 and you'll be able to know for sure if it's mites or not.

Sometime sunshine #4, which I use is a little acidic. Can be anywhere from 4.5-6.5ph. They guarantee on the website that it is a least 5.5ph, but i've read sometimes it is lower. However, you are far along and have not show issue. Did you repot? Here is the lockout chart for nutrients if it is not a mite issue.

mediums usually gain alkalinity as the plants use nutrients. This is the trend at least. hope this helps.

oh fuck no on the miracle grow none of that shit near my babies, but I am going with the a Cal / Mag def. Ive been PHing a little on the lower side so my PH might have dropped a bit this next water I PHed a little higher and added my a little higher dosage of the cal/mag. Ill see how it goes thanks everyone for the great help.
