Dying Plants month in flower

Plantproblems, First thing you need to do is get a small baby food jar or pill bottle that your pH meter will just fit into. Then gently dig out about 3 or 4 tablespoons of soil from the middle of the pot (near the rootball). Put that into the container and add just enough distilled water to cover the dirt by about 1/2". Shake it up good and let that set about a half hour or so, then check the pH of that. That will be the pH of your SOIL, and thats the value you are concerned about. You want it between 6.5 and 7 (6.8 being ideal). That will tell you what's up. Compare that reading to this table, and you will be able to see if you are in a range for any lock out.
Don't be overconcerned about the pH of anything going in. As the water that doesn't run out sits in contact with the soil, the soil will buffer the waters pH to the pH of the soil. Run off hasnt been in contact with the soil long enough to be affected too much, so it's a poor indicator as well. Trye lock out due to pH in soil is pretty rare. Usually an over abundance of 1 element will cause a lockout of another.
Do that and let us know the pH of your actual soil. We'll go from there.

Thanks Jack!

I actually did this last night (got the idea from your post) So I put the distilled water (6.0) into about 2 tablespoons of soil, shook it up in some tupperware and waited a couple hours...I then tested the water (with those ph drops from general hydroponics...I don't have a meter) and the results said 6.0

well first off we dont know the NPK values of your products but its obviously a def i still think adding 1/4 nutes and flushing them is your best option this way your not causeing any more defiencies if you get me

I agree, it does appear I need more nitrogen...Should I flush the plant first? Even with a flush, how do I raise the PH of my soil? more lime?

I'm thinking N and P deficiency, biut with 4-4-10, it cant be that. Top dress some lime (IN BABY STEPS) and re check. Maybe poke some holes in there to get some down to the root zone.
It COULD also be an MG thing, especially at that point in flower.

This ocean forest soil has been Jamaican me crazy...I used to use a soilless mix from bontanicare and never had the problems I do with ocean forest.

So just to recap:
-I'll redo the ph test
-top dress with more lime
-should I flush? With nutes?

I'm probably around week 5...the thing is I've had similar problems this whole grow so it's not like it just started...Although recently alot more fan leaves have been going yellow

Get the pH right first. Then flush with water if those are chem salt nutes. Flush it GOOD. Then water in some nutes next water. Maybe add some cal mag to it at that time. Those nutes you gave added up to a pretty high K level 4-4-10 if I remember. Try and get something closer to a 3-5-3 or thereabouts.

my nutes are 4.0-3.1-5.5 if I were giving a full dose. I only give half so I suppose they would be 2-1.5-2.75

not sure if they are considered chemical or not..I had always heard botanical was organic but not completely.

But yes, I'll flush and add more lime..should I add it before I flush to it seeps into the soil as I'm flushing? Should I flush 6.5 water going in?

Leave it along right now at 6.0. There is NOTHING that you will be able to do that will right this problem. Changing the ph of your soil takes time. Your plants definitely look locked out though. From here I suggest watering for 1 week with straight up freakin' water, maybe add a little cal mag, but that's it. Your plants have the claw which indicates that at some point, they were overferted, now they are locked out which would suggest you just needed to flush them out.

They aren't going to magically look all better, the problems will just slow down and stop spreading. Go back to 1/4 strength, then bump back to 1/2 strength, then back to 3/4 strength.

On your next go around mix lime into the soil and you can keep trying to add lime to this one on the top to get it back up, but 6.0 isn't drastically out of whack so you don't need drastic actions.
