Sensi Star problems flowering week 5

ok so here are some pics of a problem that just sprang up on my sensi star. she's grown in miracle grow organic soil with perlite, and i nute her every other watering, about once a week, a 1/2 strength dosage of bio bizz bloom, though i havent fed my sensi in about a week because of the appearance of the problem. it started on lower leaves and was really small and isolated. then within 2 days, all of my top fan leaves are affected, and look like they are gonna be dead in a few days. little bitty dots start appearing on the leaves and then it quickly covers the entire leaf and turns it really brittle. i gave her a flush about 2 days ago when the problem first srated appearing to spread. I can tell shes really hurting hard as she was growing at crazy speeds before this appeared and now she has really slowed down, lots of crystals bud bud growth is very small

nutrient burn, flush for a day or two and use full strength nutes, next time dont use miracle grow

use full strength nutes after i flush? and yeah i know miracle grow was a bad idea, tis a very ghetto grow and was all i can get in my damn town

DONT USE FULL STRENGTH NUTES AFTER THE FLUSH!!..just use 1/2 strength and go up from there, whats ur PH?? water/soil??...looks like a nute diff.. starting from the bottom up is a cal/mag or iron diff, i could be wrong...i whould read up on it...but DONT use full strength after the flush...peace.MEANGREEN.

yeah i kinda thought it was a deficiency as well. i looked at the threads here about problems and it resembled a few of them but i couldnt be sure. in soil, not sure on PH, need to get a tester. i water using drinking water jugs from the store.

HERE CHECK THIS OUT BLACKFOOT:http://www.icmag.com/ic/showthread.php?t=11688...forsure looks like a calcium deficiency some cal/mag shoule fix that i had the same prob..MEANGREEN.

Well mix the nutes, then test the ph after mixing, to high? (6.2 is ideal) then bring it down. Ph has to be factored in, sure the drinking bottled water may be fine ph but after nutes you dont know what it could be.

yeah most chem nutes will drop the ph, and most organic nutes will really drop the ph..buy a cheap liqud tester at the hydro/pet store...the wrong PH will fuck ur plants up big time.

i'm using organic nutes, can anyone reccommend a good place to get a ph tester?

ok so i got some garden lime, and i made up a mixture of the lime and half strength bloom nutes, and i'm going to foliar feed her today, here's hoping it works

well i foliar fed her a mixture of water and a small amount of garden lime and a small amount of bloom nutes. i should have thought about the fact the bloom nutes were really dark in color, as everywhere i sprayed, my plants leaves are now stained but luckily i avoided the buds, now i just have to wait and hope she gets better

Let it go completely dry hit it with Ph water 5.5-6.5 and foliage spray with sal mag
