BMO serious problems! Either a lockout or a deficiency! Too confusing to tell!

My few plants of various strains in week 6 of flowering as of today have been showing signs of nitrogen and magnesium deficiency for about a week and a half now. I thought at first I just needed to increase the strength of my nutes because I only gave them grow it green at fifty percent two waterings per week. The other two watering consist of just water. I water four times a week total because I have small pots, but they are coated with copper hydroxide. Back to the plants, hehe! They show the classic yellow leaves of a nitrogen deficient plant and classic dark spots of magnesium deficiency. I increased the nutes and even gave the plants 150% of the recommended dose of BMO. 50% grow it green, 50% flower power, and 50% SPT. They seem like they were yellowing more slowly after this, but i'm not sure. I then watered with just water, a lot of water, like a small flush, and they seem to be yellowing faster. My ph is around 6.1-6.3. I don't know what'a going on. I don't know if 50% strength grow it green two times a week alternated with plain water was too much and gave me nute lockout or if BMO has sent me a weak batch of nutes. I accidently watered them with water that still had chlorine once and that has made me wonder if I killed the bacteria population in the soil. It seems like it would be easily reinvigerated once feeding with chlorine free water is resumed. This is my second grow and is looking way more promising than the last, but how can I keep from cutting my plant's lifes short and giving them enough energy to finish strong? I am honestly thinking about switching nutes, I don't want to lose faith in BMO though. OhSoGreen, if you're out there, please help me out with this. From past posts, you seem to be the Chuck Norris of BMO products and organics in general. On a last, forgotten note, I am using Roots Organic Soil.

6.1-6.3 pH is awful low, lockout low.

Is there any dolomite lime in that mix?

BMO is good stuff and I don't think that's the cause of your problems, the pH is.

I doubt if 1 watering with chlorinated water killed off all your beasties, they aren't that delicate.

I was under the impression that this PH range was ideal? What do u Keep your PH @?

Everyone should look at using liquid photosyntheic bacteria that is not genectically modified what so ever. Quantum Growth distributed by( douglasspeed.com) is the only living microbes on the market. All other microbes are spore forming and go dormant in stress condition exist. Closing up waiting for the perfect condition to return. Photosynthic bacteria do not go dormant the form symbotic realationship with the plant creating the sugar 10 times faster than the plant can itself. Not only feeding the plant avaiable nutrients it provides everything living in the soil nutrients so there not stealing from the plants. Everyone should give this product a try my sucess with it is incredible larger girls with less time between harvest without losing Quality or weight. Indoorman

are you sure that 6.3 is "lockout low"? i dont think thats the case. everything ive read says 6-7 is ideal and 6.5ish is target.

No, not absolutely, but you are bumping around in the danger zone below 6.4 IMO.

"For me", I like to hang 6.5-6.8.

Could be he was just under feeding. If his pH was a bit higher, I could go with that. @6.3, it could be an either or type of thing.

YaknowwhatImean?

I could be totally full of shit and it's something else entirely. :dunce::dunce:

Organics is a subtle thing.

I ph everything to 6.5ish , now I may have forgotten once. would a one time slip up bite us in the ass for weeks?

It shouldn't.

That's why I asked about dolomite lime in the mix. Besides supplying cal-mag, it also keeps your soil buffered and your pH in the comfort zone.

A one time slip up would be self corrected.

I use just a bit of hydrated lime in my soil mix. I can't seem to find any dolomite in my area. I wonder if BMO's flower power has anything to do with it. I have spotting on some leaves that leads me to blame ph swings. I want to switch to Dyna gro as soon as I can. I will keep BMO products around for house plants and veggies maybe.

LOL Then you won't even need the hydrated lime. Dyna-Gro is 100% complete. I still use it for my mother plants. Good stuff.

All you will need for a successful grow is:
Foliage-Pro 9-3-6
Bloom 3-12-5
Pro-Tekt 0-0-3 A silica additive that really helps

I like the Foliage-Pro over the Grow 7-9-5, but that is personal preference. It's all cheap enough to get both and see which one you prefer.

I absoutely love Dyna Gro Foliage Pro. The max I give any of my soil plants with it is like 5 ml per gallon of the Foliage Pro. And in 3 weeks my mommas went from a lanky 2 1/2 - 3 feet. To now I've had to chop the tops off a couple cause they were getting to close to my light (6+ feet)!

While I was waiting on my nutes, I got some CNS17 grow cause it was 3-1-2. Only for a week but for vegging plants it called for 30ml per gallon!!! Show how much the big name brands water down their stuff.

Like Wet said. Those 3 nutes will do everything you need. From using pro-tekt to help propagate clones, To Bloom all the way through flower. I also have a bottle of Mag-Pro. might use it as a supplement in flowering.

But all in all I am very impressed with Dyna gro. Especially for the price. Once you use this stuff you'll go in the store and laugh at people spending all their money on supplements and miracle juices that cost a fortune.

Sounds like to me, you might just be overwatering. This could be flusing out your nutes before the plants really get a chance to use them. I'd feed every 3 days, like recommended on the bottles, and skip the waterings in between. I'd also stop using the super plant tonic. If you get too high of a population of microlife in the medium, they can eat through the nutes faster than the plant. I've used the BMO stuff for several grows, and didn't have any problems with it. I used both cal-mag and a bloom booster, in mid flowering. The cal-mag fed at 5 mg per gallon, along with the flower power at 30 ml per gallon, at each feeding. The bloom booster 0-50-30, at half strength at weeks 4 and 6 of flowering. Seems your medium is just out of balance, which happens easy when you don't have enough volume. Every little thing, can throw every other thing out of wack too easy.
