Hey guys, please only reply if you are very experienced in dealing with nutrient burn and nutrient deficiency. I do not need guesses here, thank you.
Ok, it all started in december when I noticed a nutrient deficiency on a veg crop that is now 5 weeks in flower. The crop was likely nitrogen deficient, and to counter this, a (seemingly) knowledgeable employee of a hydro store suggested I raise my nute levels which I'll admit have always been low. But I've put out great stuff for 3 years with that formula. I run botanicare.
He put me at:
Pure Blend Grow 9mls/gal
Calmag 7mls/gal
Sweet 5mls/gal
I also was adding Liquid Karma, Hygrozyme, and Silica Blast at about 8mls, 4mls, and 4 mls/gal respectively.
930 ppms
6.3 PH
RO Water
Water 2-3 Days
Coco Soil mixture (Bcuzz and HP Promix)
Room Temp 72-80
RH 45-60% (Normally at the lower end)
This crop quickly pulled out of deficiency and has been looking epic until now.
PROBLEM #1: I am seeing VERY early stages of nute burn 5 weeks into flower now. I have not changed my nute levels since adding Hydroplex 14 days in. Incredibly small amounts of browning on the tips of most of my plants and slightly more on the sides of a couple leaves on another two plants. As of tonight the plants look completely healthy otherwise.
My ppms in flower are either at 1150 or 1400. I just watered tonight and read the ppms at 1400, which I thought was way higher than I had seen before. But I did add 3.5 mls/gal of Cha Ching tonight, so I think that spiked it.
*Do I have to flush at this early of a nute burn stage or can I just back off my nutes and if so, by how much? I am about 19 days from cutting down.
PROBLEM #2:
My new vegging crop was looking incredibly healthy for the first 6 weeks of veg. 2 weeks ago, I nute burned the tips of the smaller of two strains I have. Using my 900 ppm formula. I flushed and am out of the nute burn but am now in some kind of deficiency, possibly of more than one element.
Because it was my slightly smaller strain that burned, I decided to flush everything to keep my bigger strain from out growing the smaller ones. I am finally getting vertical growth again, but my tops are not looking good. They are in 7 gallon pots. The smaller ones are at my belt height, the larger are at my navel and slightly above. Lights are 1000's and are two feet away.
Actions Taken:
I flushed everything twice, then immediately saw all green healthy tops turn yellow. Then slowly shriveling for two weeks since.
After Flushing, I backed off my ppms. Am watering the smaller group that actually got burned at 780 ppms. I did one water on the larger group that did not get burned at 820 and now they're being watered back at 900.
I do not believe I am still dealing with a nutrient burn, but I could be wrong. I see very little browning on tips and the ones that definitely did burn have regained some light green color at lower ppms.
SYMPTOMS:
Yellowing Tops
Shriveling Tops (leaves are folding in half like tacos on each fan)
Stunted Growth
Some Heavy Limbs have broken at the main stalk due to not supporting their weight.
No discoloration on bottom mature leaves, all is a healthy normal green.
Nutrients:
Normally I never have used Botanicare's Sweet in veg. The employee recommended I did for whatever reason/deficiency I was in last crop. I decided to save money and not use it in veg this round. This was my veg recipe leading up to my burn:
Pure Blend Grow 9mls/gal
Liquid Karma 8mls/gal
Cal Mag 7mls/gal
Hygrozyme 4mls/gal
Silica Blast 2.5mls/gal
PPM 920
PH 6.3
RO Water
Water 2-3 Days
Coco Soil mixture (Bcuzz and HP Promix)
Room Temp 78
RH 40-50%
I've been seeing no improvement, but a slow and steady worsening. I talked with two different employee's at two different hydro stores, and both of them thought that the tops folding in half would be due to excessive magnesium, so to back off the Cal Mag. One of them said to discontinue the Sweet. Tonight 1/27/13 I watered at:
Pure Blend Grow 9mls/gal
Liquid Karma 8mls/gal
Cal Mag 3mls/gal
Hygrozyme
Silica Blast
PPM 920
PH 6.3
RO Water
Water 2-3 Days
Coco Soil mixture (Bcuzz and HP Promix)
Room Temp 78
RH 40-50%
Hypothesis:
This last crop and this crop are both the first time I've ever had to deal with nute burn or a deficiency. So I have very little idea of dealing with deficiencies.
From my internet research the closest deficiency pictures I'm seeing, to what I actually have are yellowing tops like an Iron deficiency, and folding tops like a magnesium deficiency. As previously stated, all of my undergrowth is completely healthy.
A magnesium deficiency does not make sense to me, seeing as they were getting 7mls a gallon of Cal Mag and at a fine Ph of 6.3. However, I was not adding Sweet like suggested to me on the last round, and Sweet does have some Magnesium in it....
*Other possibilities,
*10+ days ago, we had a heat flash where I live and I walked into my room being 87 degrees. It had probably been that the night before and part of this night. Since then, it's been typically 78 degrees and not hotter than 81. I've had to grow entire crops at 84 degrees before and was able to pull it off. Seems like they should be back to normal now that temps have been down since.
*Over Watering. I've been waiting every three days usually, but sometimes two days. If I do two days, and they are wet, I give a lighter water.
