Will Cal-Mag Plus Fix This?

[hempluvr]

White Rhino is in week 6 of 12/12 and now flowering is retarded! Over the past week-10 days the plant has developed these blotches on the leaves. The plant is in ffof,being fed bat guano and low ec tiger bloom. It first started as little spots on lower leaves and now has progressed to the top of the plant. After reading a couple books,it appears this could be a magnesium deficiency. Maybe Iron? Any help would be greatly appreciated. Thanks in advance and Keep It GreeN!

that's a tough one. Being as it's been 7-10 days since you've noticed it, and your 6 weeks into flowering, and you haven't done anything irregular in your feeding cycle, it's probably not a deficiency. Looks as though it could have just been fed too much. When were the last 3 feedings, and what was your ppm?

 

[hempluvr]

PPM was only 550 or 1.1 ec. I feed low ec bat guano as well. Thing is,soon as I found the spots,I flushed her. She is in a 3.1 gallon bucket and I flushed her with 10 gallons of water. The next day it was worse! I then fed her 550 ppm/1.1 ec tiger bloom. The problem has done nothing but got worse. Before this,the plant was fed 5 days earlier with low ec bat guano. 5 days prior to that it was Tiger Bloom with a PPM of 850..or 1.7ec.

I am a newb so please ignore....but I have my plants in a 5 gallon bucket, I flushed with 15 gallons and problems got worse.....I then flushed again but this time I used about 25 gallons....I was in coco so its easy to flush....I have found that sometimes you can underflush...you think you flushed it all out...might not help but it cant hurt.

it looks to me like a pH problem,

what is the runoff?

adding cal~mag, or other nutes, at this point will not help until you identify the problem....if you crank in extra calcium, magnesium, etc., and the pH is still out of the proper range, the plant will overdose itself when and if it gets back into proper pH.

identify the problem, then use the proper solution.

you could use all the Cal~Mag in the world, and if that is not the problem, it will not help one bit.

get a pH meter...learn to use it, and keep your plants' medium in the 6.0-6.5 pH range.

sorry if i sound like a dick.

Sleepy- are there accurate soil PH testers? the only one I have seen was like $500

How do you test the soil of PH using strips or a PH pen? just test the runoff?

I find it hard to believe this would give any kind of accurate reading...

Ph is steady 6. No ph issues at all. This plant is on the same diet as my other ones. All of them are good except this one. No Sleepy,you did not sound like a dick. Any kind of help is appreciated.

lidspinner-thanks for the input.

Funkdoctor-There are cheaper ones then $500. Check out htgsupply.com.

hempluver- thanks for the link. what pens on there work in soil? I thought those were all Hydro pens???

which are for soil? the only one I see is for $24.99 and those have been known to not be the most accurate...

As Disco stated,just test the runoff! Or you can find a cheap probe that goes right into the top of the soil. Gives you a reading. But testing the runoff is more accurate and gives more exacting results. Just my

Just collect a soil sample, put it in a jar, add at least the same volume of distilled water as there is soil(1:1) (some say a 2:1 and I've even read 3:1 ratio water to soil) then simply measure the slurry with any hydro pen.

this will give you an accurate soil pH if you wait at least 30 minutes after adding distilled water to the sample.

Distilled water has 0 buffer and will "take on" the pH of whatever is added to it.

ok...you didn't mention your pH, sorry i was noi help.
