DWC Using Advanced A + B Sensi bloom....

I am using Advanced Sensi bloom A + B and am in the second week of flowering. I have picked up what looks like a mag def, but it's greening back up from some cal-mag. Now here's my question. I am only using the bloom A + B and superthrive. Does anybody know from experience if this is good to use without using the rest of the line. I plan to use Big Bud and Overdrive at the end. If Anyone knows where my ppm should be please let me know. Any Advanced Nutes Advice would be helpful.

Also, any info on Dutch Gold?

You can definitely stick with just the two for the entire flowering. They have a lot of additive products that you can use to tailor your grow as desired, but they make it so they aren't necessarily needed.

I was looking into Overdrive and Big Bud myself, but ended up going Botanicare and General Hydroponics mixed, so never bought them. They definitely looked good, and I definitely will get around to trying them.

You will want to stop using Superthrive sooner or later (probably sooner unless you have a N deficiency). It has a high N content and that is usually not needed in flowering.

I was going to knock off the superthrive once I totally ironed out my cal/mag def. chasing one thing at a time. Does anybody know what ppm I should be at with 188 ppm 8.0ph water, in the third week flower? Anybody with advanced nutes expertise??

Well, it's different for different strains. In my buddy's setup, his vegetative sits at about 1400ppm, then he drops it down to 1200ppm for the first week of flowering. Each week into flowering, he raises it 100ppm, so week 1 is 1200ppm, week 2 is 1300ppm, etc.

So if my tap water is 188 ppm I should add 1012ppm then the following week 1112 ppm and so on and so forth? What about big bud? Should I back off the bloom a+b to half and make up the difference with big bud? I really appreciate your help. The lants look lime green and the lower fans are yellowing. A little soon IMO only going into third week of flower. My ppm with 188 ppm tapp water now are 1039ppm.

Ok. First thing go to the advanced nutrients web site and do their online calculator. Enter your rez size and whether you want American or metric measurements. Select the Sensi product line and medium flowering. It will calculate everything you need. You don't need to add what you don't want. But it will include the values for big bud and overdrive.

Big bud finishes off early in flower so get on it now. If you are going with the Advanced stuff I would add carbo load and B-52. That group of products will do great. There are some better alternatives, but this is good.

Also, don't worry about the ppm. It is VERY misunderstood. Set the meter aside for the next few grows then see if you still feel you need it.

i'm running the same nutes as you late in flowering, going at 1400ppm with Big Bud and so far everythings great.

Really surprised to hear about an Mg def, esp w/ source water that hard- how's yer pH?

Lose the superthrive.

I was also suprised to see the cal mag def too. They bounced right back and havn't added it or had trouble since. I have up'd the nutes each week and the ph is stable @ 5.6. Towards the end of the week it rises slightly but no visible plant problems. The Sweet really made them stand up and salute!! List of nutes currently using:
sensi a + b bloom
sweet
big bud
purple maxx (only on two as a test)

everything is sound thank you all, pics coming soon.

rhiz, you mean for flowering right? I did. Is there anything you see on my list that could be added or lost?

ok mag def back again. I corrected it quickly and all is well. The purple maxx is the bomb!! I think the mag is ph related, no big deal easy fix and running smooth.

Overall I was happy with the grow. The Advanced worked well except odd def's showing up here and there. The purple maxx....well let's be fair and say it may have added resin but it FOR SURE cut yeild by 50%. I am now switching to Botanicare with advanced supplements. Anybody using or used the AN A + B?

whoa whoa whoa, rewind that.

MG deficiencies (in MY experience) appear DUE TO HARD WATER!!

why?

well,the water is usually 'hard' due to excess minerals, one of those being CALCIUM.

now, MJ doesn't like too much calcium. give MJ too much calcium and WHAT HAPPENS....CALCIUM LOCKS OUT THE MAGNESIUM!!

so, if you are using HARD WATER and NOT giving an epsom salt treatment, then you are MOST LIKELY experiencing a MAGNESIUM deficiency!!

believe me, I have experienced this problem in ALL of my grows (hard water can be a BITCH!!) so a MG deficiency is EASY to spot if you know what to look for.

got pictures?

A MAGNESIUM def. will result in COMPACTED "STUCK" GROWING TIPS THAT RESULT IN SLOW GROWTH.

Your fan leaves will start to yellow around the EDGES of the fan leaves. (It looks NOTHING like a N deficiency, if you are familiar with an N def....)

So, I would start with a good FOLIAR FEED OF MG (get some epsom salt, in your local pharmacy section...).

Get some DISTILLED WATER and add epsom salt until your ppm is about 150-200ppm. Spray your plants until they are nice and soaking (DO NOT SPRAY WHILE HID LIGHTS ARE ON!!!!! it's okay to spray while flouros are on).

spray every other day until you get your nice green foliage back. you could probably add some epsom salt to your res, but I don't know enough about hydro to advise such an action.

I totally agree with you nut this showed up randomly and was just a slight one. I think that the def showed it's self just before res changes. The strain was eating! Any way it wasn't throughout the grow just random so not too worried about the water as I use it with all my grows. Thanks

Don't forget you can always call AN and ask 'em whatever you like. Obviously they can help most with their own products, but they don't care what you're growing or what you're growing with.

I keep the number around here somewhere... 1-800-640-9605. I haven't had this particular problem yet, but they've always helped me out when I called. The only drawback is it's not open 24/7. They get up pretty early for west coast and are up pretty late, but no weekends, darn it.

Never hurts to ask. I mean sure, you'll get their answer to the problem but ultimately they want you to buy more AN stuff, right? So they'll want to make sure you grow well and like the results.

At least that's been my experience.
