Sick Urkel...

[Morrow]

So this is a Urkel clone that I've been trying to get to re-veg. It briefly started to flower for about a week before putting it under a 18/4 light cycle. She's planted in a peat based organic amended soil: blood/Fish/Bone meal, HP bat guano, seaweed, green sand and dolomite. She's been a bit sluggish in growth and about three weeks ago I noticed her leaves were a funny dark blueish/green color with the purple creeping way down the leaf..then she started showing these necrotic spots.. I thought "phosphorus!" so I fed her some guano tea that was brewed for about four days...no still not the answer....What do you all think is going on?

phosphorous still might be the problem dude, do you know the pH? I would never ever try and fix a nutirent problem without first knowing the pH and ppm of your soil.

you really need to fill out stitch's questionnaire. I know it's kind of long and arduous but it's necessary in order to really find out what's wrong with your girl.

SOIL:

How long has this problem been going on?
What STRAIN are you growing?
What was the establishing technique? (seed or clone?)
What is the age of your plants?
How long have they been in the soil mixture they are in now?
How Tall are the plants?
What PHASE (seedling, vegetative or flower) are the plants in?
What Technique are you using? (SOG, SCROG etc)
What size pots are you using? (Include how many subjects to pot)
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?)
What Nutrient's are you using?
How much of each nutrient are you using with how much water? *Knowing the brand is very helpful*
How often are you feeding?
If flowering, when did you switch over to using Bloom nutrients?
What order are you mixing your nutrients? (example: veg nutes 1st, bloom 2nd ect)
What is the TDS/EC/PPM of your nutrients used?
What is the pH of the "RUN-OFF"?
What method of pH test was administered? Using Strips? pH pen?
How often are you watering?
When was your last feeding and how often are you feeding?
What size bulb are you using?
What is the distance to the canopy?
What is your RH Factor? (Relative Humidity)
What is the canopy temperature?
What is the Day/Night Temp? (Include fluctuation range)
What is the current Air Flow? (cfm etc.)
Tell us about your ventilation, intake exhaust and when its running and not running ?
Is the fan blowing directly at plants?
Is the grow substrate constantly wet or moist?
Is your water HARD or SOFT?
What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water?
Are you using water from a water softener?
Has plant been recently pruned, cloned or pinched?
Have any pest chemicals been used? If so what and when?
Are plant's infected with pest's?

Hate to say it, but that doesn't look like Urkle to me... Do you have another shot of the plant?

umm..

umm..

I can't answer some of the more telling questions. I don't have my PH pen right now and have never owned a TDS meter. I wasn't exacting in adding organics to my soil, it was like a tablespoon of each into 3 gallons of soil. Never mind then I'll just have to figure this out myself.

I'm pretty sure it's an Urkel, from a NorCal club. But maybe it's not. I'm not too concerned with "brands". Here's another look if you like...

Looks like a few as darker, bluish green indicates early P- when this gets worse though, the dead patches will be a dark color, not bright/light brown. This is more a K deficiency, also noted with leaf edges slightly turning upward & slight yellowing moving inward from edges.

When I revegged a plant, it really wasn't happy for quite a while- new veg growth took almost a month, if I recall. They need almost no nutes @ this time as not really growing- just major hormone imbalances. Depending upon how you feed/nute, there may be pH issues & some lock-out, contributing to your issues. ps, it won't look like any normal plant while revegging, so...

The major source for my soil K is from green sand which I keep reading will take a long time to release. What else could I use that's tea'able and fast acting, Dolomit? I've been running with that already though. anybody?

 

[crankndapot]

to me it looks more like a phosphorous def.. not K. Also, how hot is it in there? id probly just flush the medium if i were u. and let tap water sit out for a day before usin it. it'll make chlorine inside evap and lower ph a bit. i have hard tap water like 8 ph, i leave water out for day its down to 7.. so if u have no ph tester, that might help.

So I watered with distilled water for two waterings, trimmed all the effected leaves, so that I could tell if the def. was progressing and, well cross my fingers, all looks good, she's actually picked up in vigor quite a-bit so whatever happened seems to be behind me, Thanks for the replies.
