Yellowing + Brown spots on lower/middle fan leafs into flowering | rep+

read the bag it came in and see if it has time release fertalizers in it. if so flushing is just going to release alot of nutes into the soil.

Hey Kevin - It's only been about 18 hours since the flush but so far so good. Before the flush my fan leaves were looking real droopy and this morning when the lights came on they were looking back to their perky selves. I think it was too many nutes but can not be sure until a few days pass so I can judge better.

I have no idea about mg soil - why would you not be able to flush it?

Well i think its doing well, report here in a few days if you can and post the results tnx. Well MG has time-release nutes and if you flush it it may activate a lot of them and course serous nute burn, that what i have read.

Yes all MG come with time release fertilizers (yes, i checked) but it last not all that long, so as i'm already feeding it flowering nutes i think its all gone and a good flush to clean out all the salts and shit would be good.

Should i flush MG or will it kill the plant, i dont think there much time-release nutes left anyway?
Should i leave it alone as the buds are in good condition or will the flush make it even better ?

That amount of yellowing off on the bottom of the plant is nothing to worry about at week 4, it's natural.

The tips of the newest growth do show a bit of nute burn, not terrible, but burned none the less. I wouldn't do an all out flush on the plants, just feed them pH'd water the next couple times and feed again at slightly less ppms.

I will do that, I was wondering if the tips are from slight nute burn and i was reading up and then you answered that question for me, ill just use plain pH'd water next few watering then so. Forgot to ask, would it be a ok to still add molesses to the water?

Thank you.

Yea, you can't really burn your plant with molasses. Use about a tbs per gallon of water. Contains a little N and some good micro nutrients for the plants as well as feeding the rhizosphere.

Well Kevin, Sorry to hear you havent figurred it out yet. I took another look and everything I find comes right back to a magnesium difiecincy or perhaps a zinc deficiency as the symptoms are similar. I guess 1 way to find out is to water with 2 tbsp of epsom salts per gallon of water or if you really want to find out quicker apply a 2% epsom salt solution to a leaf and see if that leaf has a change within a day or 2. Also here is a very useful chart I use in my grow room that may help.

That's a great idea - to foliar feed a single leaf with some epsom solution - i think i'm gon'na try that too.

Thats' cool IXOYE glad I could help..., and thx for the +rep too
It's a quick way to tell on the mobile nutrients like mag, iron, and zinc w/o risking additional and possibly unneccesary stress on a plant. If mag turns out to be the deficiency just bare in mind that the recovery will occur with the plant greening from the top down so you may have to be patient if watering w/ the epsom.
