Someone please confirm my hypothesis:

My plants started off green and vibrant. Then:
-I noticed grey tips on the bottom leaves which turned yellow plus twisty bottom leaves
-After the yellow they (the tips) turned brown
-After the brown tips the whole leaf started yellowing
-So I flushed and left it for a day
-The day after I flushed again with pH'd water (1gallon; container is 14oz.)and immediately nuted with pH'd nutes (you know, like i add the nutes then ph the water) with recommended dosage for seedlings
-Now the yellowing has either halted or slowed down and the tips have also been fine

This would be what? N def. or nute burn or pH or combo?

Let me know, thanks, I had such a hard time diagnosing this retarded situation.

PS> after i pH'd i tested the solutions to be at 7 using the colour guide

G'day maspino1,

I have a limited knowledge on this, as I am starting my research in this area...

There are many variables you need to consider when diagnosing problems eg: Young leaf, old leaf, stage of growth (Age of plant), environment, mediums, etc...

Appears you have had a combo of - deficiency and perhaps PH issues, though the turning down and browning of tips can indicate nutrient burn but, this can be normal for older leaves nearing harvest (Old leaves will turn yellow and eventually drop off). Here are some systems/reasoningâ??s relating to your post:

1. Yellowing of lower leaves = Nutrient deficiency (dependent on age of plant?) and or PH too low and water is acidic
2. The turning down of tips and browning = Nutrient burn
(Turning up of tips and side of the leaf and evedince of browning = Heat issue)
3. Mature leaves turn yellow and edge areas turning dark grey = Nutrient deficiency OR just old leaves dying (There are slight differences you need to know)

Hope it helps a little...

Cheers!

Lockout from too much fert in the soil. Classic to see both tipburn and N def on the same plant. Too much of one thing and too little of another lol. Imbalance. The salt buildup in your soil making the roots unable to selectively transport certain ions across a membrane.

I'm stoned. I need to go to bed with a pile of comic books and a hot cocoa. G'night.

thanks for the answers, i guess it must've been pH issues then
i'm gonna see how it does for a few days and then update if things are still pretty shitty

omg my runoff is perfect now, it's yellowish green so somewhere between 6.5 and 7.0
so pH issues are out
the only thing left to consider is:
-over nute/nute burn
-N def.

overwatering isn't possible with my medium so i've already passed that consideration

PS> yellowish-green run off in reaction to the reagent

this brings me to another point, since coco is soilless it's in the category of hydroponics right?
i mean when i water it's pretty much like ebb and flow or top drip where i run water from
the
top and let it drain....
so would that mean i have to go down to 5.5 like hydro??

In relation to PH and hydro, a suggestive guide, hydroponic systems run a PH level between 5.8 - 6.3. I keep it stable between 6.0-6.2 with a water temp of 25 degrees celsius (77 degrees fahrenheit)

I'm not sure, lets look at it - grin:
- Coco is in the category of "Mediums"
- Hydroponics is a system that utilises mediums
- Is Coco specific to Hydro System (I'm not sure)? If so, then your query is the right one...

Cheers & Enjoy!

lol thanks jmd, it still hasn't gotten better, im not sure if the browning is turning green
or there's more light green patches about to turn brown
ay...
thanks for your help guys

If you were able to get some pics of your troubled plant and post them in this thread, I'm sure we'll (Others in forum etc) be able to disgnose the symptoms more accurately...


Besides that, it'll be fun researching/troubleshooting the issue etc - grin

Cheers maspino1
