Help with Tips browning

First time growing and doing really great with the clones. Two straines on the left are LA Confidential and the two straines on the right are Bubba Kush. They are about two weeks into flowering and they are doing good. But i have noticed a leaf or two on the plants half way up are turning brown on the tips. What could be causing it? I've been using nutes at the right mixing volumes and everything. Any ideas?

Here's the pics....

I have two leaves on my plants ( the first set of true leaves) doing the EXACT same thing and I have NO IDEA why. Mine are only a little under 2 weeks old tho.

if its browning from the middle it may be magnesium deficiency

a tablespoon of epsom salt in a gallon of water should fix that up

it wont fix the bad leaves but it shouldnt spread. (if mg def)

i had this problem, it spread quick and wiped out most of the leaves
on two of my plants

so should I only have to do this one time to fix the mg deficiency? Should I mix the epson salt in with my nutrient watering jug or just my regular watering jug? How should I do this and how long should I do this?

Same question.

bump for kindness the kindness of herbs


sorry, im retarded stoned right now LOL

You can use the epsom salt/water mix as a foliar spray too, for faster results. You can spray a few times each day.

Try and find out why there is an Mg deficiency, and fix it. Maybe your water's pH is too high/low?

and as foliar spray you mean, spray the plant its self right?

Check your ph. The leaves are starting to do the "claw", it looks like. Water with pure 7.0 water until you get 10 to 15 % runoff. Check the ph and the ec. You should know right away.

Would spraying water on the buds make them mold?

nah man, dont directly spray it on the buds, but a mist over them doenst hurt, usually the fan and light will dry it up real fast, just give it a good shake to get excess water off, not to hard tho hahaha.

Don't spray the foliage until it's time for lights out. You should never put a wet plant under HPS, or the water droplets will act like magnifying glasses and cause burn spots on the leaves.
