Sensi Vs G/m/b An

[Bashar Assad]

So I have three one liter bottles of AN grow/bloom/micro. A few days ago I got a parcel in the mail that had 2 ona pucks that I ordered in it as well as AN sensi grow A & B which I wasn't charged for. Anyways i decided why not order the bloom as itll only be 40 bux for the two bottles.

So I've been using the g/m/b on two star ryder seedlings from dutch passion that are 3 weeks old. At the 2 week mark they both seemed to exhibit signs of potassium deficiency. I started giving them a solution of 105ppm at this point and they've stopped in progression in decifiency signs.

Yesterday I changed thier reservoirs and gave them fresh nutrient solution of four liters each. For one bucket I used the g/m/B at 1/4 strength and had a tds of 145ppm and a ph of 6.3. The other bucket I decided to try the sensi grow at 1/4 strength for a tds of 145ppm and a ph of 6.4. I changed to sensi of the plant that seemed to get the worst of the deficiency issue they both had, so the tips of its older leaves are more burned.

Long post short, I'm wondering first what the main difference of the two nutrient regiments are. Also is there a benifit of using one over the other?

I'm kind of doing a little experiment with this atm, right now the seedlings are each in thier own separate drip bucket system so the nuteient solutions they get are independent, but all of the other growing variables are nearly the same (water temp, light, %rh, temp, ph, tds (pretty close to the same)). I want to see which plant does better over the next 3 weeks as I'll be switching to using a main reservoir bucket feeding three plants and recycling the water back to it. I want to see whether the G/B/M plant or sensi grow A & B plant grows better overall. Then based on which one thrives I'll choose which regime to use. I'm just looking for anyone with some knowledge they could shed on me with the differences of them or even thier preference and why.

Thanks

145 ppm ? That seems pretty low dude. What scale sre you using, 500 or 700. Are you sure thats right?

The bottles say to use 1ml per liter and from what I've read with AN nutrients it's best to start at half or even quarter nutrients for the first bit of introducing the seedlings to nutrient water. So I used 1ml of Bloom, 1ml of grow and 1 ml of micro in one 4 liter reservoir and 1ml of sensi grow a and 1ml of sensi grow b in the other 4l reservoir.

From everything I've read in the cannabis bible and medicinal bible starting with a tds of 50-150ppm is best and then working up from there to about a range of 800-1200ppm by harvest (although that's a high figure I believe, I think I read it's best to aim for around 500-800ppm if you're new due to the potential of nut. Burn at higher ppm). But I don't have all the notes I've taken on me atm so I may be off with the ppm ranges, that's just iirc.

My seedlings have just about completed one week of nutrient water watering and will be bumped up to half strength nutrients next Tuesday for a higher ppm. They seem good atm, no burn and the potassium deficiency they seemed to have has gone away since I started using ~140ppm solution for a week.

What do you mean by scale?

1.0 ec, is 500 on the 500 scale and 700 on the 700 scale.

2.0 ec, is 1000 on the 500 scale, and 1400 on the 700 scale.

What kind of lights you using?

Less is more, is a good general rule.

Best of luck.
