Waaay Waay too much on the Grow!!!!...geesh. I noticed you used the term 'tbsp' and not 'tsp'. Well if you did indeed use actual tbsp's then yea.. you might be a lil to heavyhanded on the grow nutes...but but once again let me say, I dont know what the exact EC of your Nutrient line up is but from the amounts you are feeding at relative to the average amounts fed amongst different nute lines when used in addition to other fertilizers, is that you're feeding amounts are a little high....I suspect you read the back of the bottle and fed to spec as they recommended. But did not realize that, the specs are best to follow when using Only that fertilizer and nothing else, but when used with other ferts. you have to adjust dosages and also factor in the particulars of your strain. some strains might be so sensitive that they cant take even the recommended dosage from a single bottle of nutes. , As to avoid nute burn which can happen very quickly when mixing ferts, just remember its ok to do so but just keep in mind that less is better. As far as your Sensei Cal Mg Mix( my 2 cents on that is...if you Look at the NPK breakdown on that bottle and compare it to the NPK breakdown on the "Sensei Grow A" bottle you'll see that they are pretty much the same thing (which I can go into detail for anyone that needs an explanation on my generalization or maybe even more, some specifics you dont know about.)
But I make the comparison, to let you know that the Advanced Nutrients Calmag really doesnt cut it as a true Calmag supplement for me. See, 'Advanced Nutrients' have capitalized on fragmenting their product line, by taking micro Nutrients and the Macro nutrients that could go in 1 bottle and separately selling each product separately...if that makes any sense to you lol. By definition they're calmag is just that Calmag(Calcium, Magnesium, Iron, and Magneese) But it isnt a COMPLETE supplement because its missing 9 other micro nutrients that your plant needs in very small amounts but still need and cant be left out.....what kinda sick twisted company does that!!?? wtf!
So I would suggest replacing your AN Calmag with something like Botanicare calmag+ (dont forget the 'Plus' when you say it) or go with the FFOF nutrient line because their "GROW" and their "BLOOM" nutes contains trace minerals as well(by trace minerals they are refering to those micro nutrients that your plants require....I mean....you already have the soil so why not get the nutes)
Dyna-Gro is another tried and true oldschool brand that offers the COMPLETE line of Nutrients in their Grow and Bloom nutes.But they are not an organic Fertilizer, they are a chemical fertilizer and a great one at that. One thing some growers like to do is Use a chemical fertilizer for their Vegging stage and then when it comes time to Flower,thats when they start using organics Blooming Nutes...which makes sense if you think about it.
Now I talked to you about your Nutrients and what I THINK is too much...but I have to say, ONCE AGAIN I CANT BE EFFECTIVE AS NEEDED WITHOUT THE NUMBERS so I say again...you gotta get you a bluelab ph and EC meter pen brotha..But in the mean time less drop your grow from 2 Tablespoons to something like: 1-1/2 TEAspoons of Grow...speaking of Grow...your NPK numbers looks kinda funky...after checking the Biotics Grow site I didnt see a Grow Product with that NPK breakdown the closest thing I saw was (3.7-4.3-1.4) I'm guessing you rounded off to the nearest whole number....(sneaky bastard..lol) but anyway back to what I was sayin bout your dosage regime. lets go with something like 1-1/2 TEAspoon of Grow Biotics, and 2 TABLEspoon of Their Bloom Mix and nothing else!(That bloom mix is cool but just know you'll prolly need something wit a little more muscle when it comes time to Bloom. Anyhowzers lets see how the plant responds when you put the feeding at this mark. BUT!!! DONT just go trying this out without a game plan. You have to set it up right!, If you already fed your plants Today or Yesterday then just wait for the next feeding cycle to come around.
But once the feeding cycle has come and you have adjusted your feeding dosage After you give the plants this...we have to wait a day for the results. BUT!!!! THE KEY TO THE RIGHT FEEDING IS to NOT ACCUMULATE YOUR NUTES FEEDING, meaning you feed them on Monday, /Tuesday-you dont feed cuz they dont need it/ Wednsday you dont feed them cuz the pot feels 50% heavy, then Thursday-you dont feed but you notice the pot is getting light, then Friday you notice pot is Light. And your plants are kinda drooping so you say...'HEY LET ME GIVE THEM SOME NUTES...its time for another feeding'....WRONG!!!! dont do that!
What you would do...no matter how hungry they look, is you will FIRST FLUSH THEM OUT BEFORE FEEDING!...this is protocol specially with FFOF soil(as they do mention this on their feeding chart google it) but thats what you do, I've tried some other feeding techniques such as Feed-feed-flush-feed-feed but This can only be done once your plant gets its appetite fully established. But even then you cant do that kinda thing week after week. But with that said...ONCE YOU have flushed them you can feed them immediately after flushing or wait as long as another full day because you are giving the pot some time to drain fully and allow the root hairs total availability for full uptake. This works very well because if your potting soil drains well then..on that next day when you do feed them...they're more likely to retain more Nutes as oppose to only a small percentage of the nutes had you fed them immediately after flushing. The only advantage to feeding them right after a flush is you kill2birds with one stone by getting they flush and the feeding done all in one session.
