looks over-watered to me..wide/drooping leaves.... with that, easily comes over nuteing which it looks like is also happening.."burning" in the middle

I think he is correct. Ease up on over corrections. Tell the pros what soil,temps,species, etc. They will get u straight

What kind of water? If it is tapwater then I higl doubt that it is a mineral def. Maybe tho. WHere I live the water is the hardest in the world. Sorta. Anyway, dont be afraid of fish, it is killer and dont over due the blood meal it will burn. Also think about compost teas to restore plant health. Good job with the ph, adding base all the time is lame, so try a topdress of some espoma garden lime from hd or some other dolomite lime, as finely ground as possible. YOu can add guano later as a topdress of a couple of tbsp, it might burn so not to much.\



I am real curious tho to see what results you come up with. I also sometimes add botanicare cal mag plus to ro water when I use it.

over-watering may have been an issue...but as i stated before, i didn't add any nutes before they started yellowing/browning.

Info is on the first post...

just for a reminder, soil is pro-mix, temps are between 68-75, water Ph is now around 6.6...and i haven't checked the runoff of the soil Ph in a couple days as i haven't watered them...next water i'll check the runoff.

Yeah, the plants are looking better this morning since I foliar fed them the ph'd water w/ the epsom salt and the straight water flush. And yeah, It's tap water that had a PH of about 7.6 before I down'd it.

Only problem I have now...which I think was the problem from the beginning, is the soil Ph is going to be low from the sphagnum peat moss in the pro-mix. I have some finely ground hydrated lime...but i've read mixed reviews on it, some saying it'll burn your plant and some saying it'll work to buffer out the PH.

If anybody has any GOOD info (as in you already used it) on hydrated lime let me know asap. If I find out it'll hurt the plants then i'll go get some dolomite before the final transplant and mix it in w/ the soil.

Thanks for the replies.:wall:

I am guessing you have never used hydrated lime. So in my opinion I wouldnt. I am a farmer and know first hand hydrated lime is a bit of an art to work with. Especially with and already established crop. We only use it late fall or early spring well before planting. Go with the dolomite. You can top dress, mix with water or mix into you soil before transplant as you stated. Also runoff ph and soil ph are 2 different things. The only accurate way is to test the soil directly. And you want to keep that soil ph around 6.5 give or take a few points. Checkout Jerusalem Stone on ebay. Theirs is the shit. Straight from the Holy Land. And Ben is a great guy to deal with.

Your pH is imbalanced.

I think it looks more like a magnesium deficiency than anything. This is very common amongst cannabis.

Foliar feed 1 tablespoon epsom salt to 1 quart of water.

I use dolomite lime in all my grows. When i replant the seedlings. I top dress the top 2" of soil with about a 1/4 cup lime. then water. the lilly miller garden lime has cal and mag. I would never foliar feed with salts. Thats just me.

Why wouldn't you foliar feed with salts?

It even says in the FAQ that epsom salt can be foliar fed...do you have firsthand exp. with it?

Hey Stumps, how they hangin? Anyways have you ever considered just adding the dolomite to your soil mix a few days before transplanting? Gives it a bit of time to react. Top dressing works fine I know. Gotta tell ya though. A few lead days prepping your mix. I.E. Dolomite, greensand, perlite, vermac ect.... Whatever your amendments. I really think it helps to let thing buffer together a few days. Just a thought, PEACE>>>>>>>>>>>>

Yeah, I plan on doing that when transplant time comes.


edit: what do you guys think about transplanting to new soil. premixed with lime & bloodmeal that way it'll get sufficient N and have a ph buffer.

To tell the truth I've never thought about it. I was having retarded leaf's cupping I think is the right term. I talked to Dr. Dank he told me to add the lime before watering. I did. It worked. Been doing it the same way ever since. I'm also using a coco blend medium

yeah, i would just add the lime prior watering but i only have hydrated lime available and i don't want to take the chance of burning them since hydrated lime is faster acting than dolomite.

i guess now, the question is should I mix a gallon of water with a tsp of hydrated lime and use that for next water, or

repot with a new soil mix -

-promix
-blood meal
-small amnt of hydrated lime
-perlite


i think i'm gonna be forced to choose one as the soil PH is still low...but i don't want to burn them with the hydrated lime.

Flushed 1 plant with 7.4 ph'd water tonight....


all other methods have FAILED, so this is a last resort. I ph'd the soil to 6.7.


if this works i'll go ahead and flush the other plants to 6.7 as well. let's hope for the best.

ph down?

the soil was VERY acidic. in the 4's. i flushed the hell out of it until it hit 6.7...and now i'm leaving it.


the WATER on the other hand is around 7.5 tap. i could ph down it, but it kind of stabilizes the acidic peat moss with the alkaline water.

so....ph is around 6.7 for all plants tonight.

the plant i flushed yesterday is doing alot better, so in a few days i'm guessing they'll be in good enough health to flower in a week or so.

hoping for at least 2 females out of 4...would've been 5 but the cat got a nice midnight snack. mother fcker.
