Not heat.Shouldn't be ph as it's been fixed.Cool temps were becoming an issue since fall has set in but that too has been fixed.It remains 77-78 constant now.Does this look like Nute burn or phosphorus Def....Or even offgassing from my sunhut?????Though the hut does not smell like plastic at all and the 2 main doors are left wide open for my fans to draw fresh air in.

What STRAIN are you growing? kush and blueberry

What was the establishing technique? (seed or clone?) Clone

What is the age of your plants?50-60days(roughly)

How Tall are the plants? 8-18 inches

What PHASE (seedling, vegetative or flower) are the plants in? Flower

What Technique are you using? (SOG, SCROG etc) SOG

What size pots are you using? (Include how many subjects to pot) 1-2 gallon a few in each size.

What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?) 75% hydro mix HP 25% Happy Frog

What Nutrient's are you using?How much of each with how much water? How Often? *Knowing the brand is very helpful* EarthJuice Grow 10ml/gal... Humbolt Honey 10ml/gal ....Liquid Karma 5ml/gal ....Sensi Cal Mag 15ml/gal

What is the pH of the "RUN-OFF"? 5.7-6.0 Fixed for 2 weeks + runoff is now 6.7ish

What method of pH test was administered? Using Strips? pH pen? Pen

How often are you watering? every 4-6 days as needed..Allowing the dirt to dry 70% out before rewater.

When was your last feeding and how often are you feeding? 10 days ago.Feed once every 2 weeks roughly.

What size bulb are you using? 1000w Sodium + 400w sodium

What is the distance to the canopy? Was 20 inches just moved it to 30 inches

What is the canopy temperature? 75-82 Got down to 60 for a few nights before I added a heater to keep it @ 77

What is the Day/Night Temp? (Include fluctuation range) Same as mentioned above.

What is the current Air Flow? (cfm etc.) 6" inline 435cfm on a profilter75 and 2 large oscilating fans blowing fresh air into the room.

Is the fan blowing directly at plants? Osciltating fans are.

Is your water HARD or SOFT? Hard but not extremely. Iron is 1.5ppm with trace amounts of manganese.

What water are you using? Reverse Osmosis (RO)? Tap? Bottled? Well water? Distilled? Mineral Water? Well Water.

Has plant been recently pruned, cloned or pinched? No

Have any pest chemicals been used? If so what and when? Azatrol when in cutting stage nothing since.

Are plant's infected with pest's? No

In addition they are in a Sun Hut XXL..The main doors always left open with oscilating fans pumping in fresh air...This problem started early on I fixed my low ph but it hasn't seemed to help.

when you say heat spikes what are your temps...how close is the light....how soon from rooting were they transplanted?

Kooza · 10-13-2008, 10:50 PM

Temps stay 75 to 80 but hit 88 a couple days.
Light was 20 inches since has been moved to 30 away.
They were well rooted when transplanted.

heat doesn't sound like it's too bad, looks more like a Mg def, I also noticed your pH is a little low too.

Kooza · 10-14-2008, 02:33 AM

Forgot to add in the nutes Sensi cal mag was added @ 15ml/gal so I am not thinking its a mg def and both the fert'd and unfert'd plants are showing the same signs.

Kinderfeld · 10-14-2008, 02:56 AM

There is some small lockout perhaps. You want runoff of soil to be 6.5-7.0 I also use strips....5.7+ is much too low for soil...perfect for hydro. At 6.5 to 7.0 some strains like higher, some lower but complaints are rarity when kept between the two if it had to be higher or lower I would go higher. I get a 6.5 runoff but I have to water with 7.5-8.0 water to get that. Doesn't really matter becasue everything else looks good so once you get your ph straight you shouldn't have any probs.

Kooza · 10-30-2008, 07:46 PM

I have bumped my ph to a 6.5 to 6.7 runoff.Watering in around 7.1 and this problem is still ongoing....Been a good 2 weeks at the proper runoff..Only thing added to the water was a low feeding of cal-mag and EJ bloom one time.The rest has been straight water.Any ideas?

Kooza · 11-04-2008, 11:53 PM

Bump I added new info to my first post and need some help here.....Next round I am going to use blaze's soil mix maybe it will be less hassle.First 2 grows went great with the method I am using now but this one has been a pain.

Kooza · 11-06-2008, 07:18 PM

Anybody???? I had the tds of my tap/well water tested and it's 500...The guy at the hydro shop told me I should be setting my nute solution @ 6.0ph to water in and not worry about run off which from reading here is complete bs....I really need some input...Should I feed again or not since the ph was low and has now been corrected? Could this be burn due to build ups of nutes when the ph was low and now that it's corrected to many ferts being released or has 2 weeks of watering in plain water leached out the nutes and now I need to add some due to deficancy???

11-06-2008, 08:18 PM

well i agree that it was a nute-lock out due to a ph problem that probably resulted from the feedings and salt-build up locked things up a bit...if you flushed everything out (i'd recommend pure blend clearex) with an adjusted ph balanced water everything should be good to go...the signs of the lock out won't disappear but it shouldn't get any worse...the key now is to look for signs of any deficiencies and work from their...if you were gonna feed i'd recommend it very light (1/2 strenngth max) and water around 6.3ph with nutes...i try to keep my medium at 6.3 which is optimal as almost all the nutrients are readily available with a soil ph of 6.3
