CalMag and Thrive in bloom...

[BlueDevil]

It's my understanding that N should still be fed, albeit in smaller quantities, during bloom but you need to knock it off in the last few weeks. Is this correct? Calmag is rated at 2-0-0 so phasing it out say halfway through bloom would be a good idea?

While I'm here, I should also ask if a similar rule exists for hormones a la Superthrive? I hear people mention they use ST all the way until harvest, but I've also picked up that it can actually hinder full errr, fruitilization!



Heh. Whatcha think?

I use CalMag all the way through.....using RO water and if you do use RO water I suggest you do the same. The superthrive q I cannot help you with...sorry.

No superthrive or thrive alive in flower unless you have to transplant, and if you do, only 1 dose.
Calmag is good though. That amount of N is not going to make your plants get all leafy or anything.

SuperThrive only helps with rooting, despite all the 'miracle' claims - using RO water is no guarantee of pH - I found out the hard way, my RO water is 4.5 ! - it seems heavily chlorinated city water acidifies, even if filtered thru a reverse-osmosis setup, like mine - TEST YOUR pH !! :smokin:

Frank - you seem to be pretty opinionated about Superthrive. I hope it's an educated opinion because I have a question for you. The pH on my water, RO and tap, is around 7.0 - 8.0. Sometimes I use Superthrive to bring the pH down. Good idea? Bad idea? Don't know?

Bad idea. Too much superthrive can, as my old grow shop guy used to say, 'put the plants in a coma'... Lots of action below ground, nothing up top. Frank is pretty damn experienced.

I assume SuperThrive would acidify your pH to some extent, but have not tested it, because I don't use the stuff much - according to all my local nurseries, and a friend-of-a-friend that is a working botanist, SuperThrive is nothing more than Vit. B1, and 'urea' (urine) - urea, urine, piss, whatever, is a strong nitrogen source, (which is why peeing on your plants is a no-no) - a strong source of nitrogen like that could lower pH - I had problems with many seedlings only after trying Superthrive (as directed, only a drop or two per gallon) - I researched it pretty heavily, and I do believe that it stimulates root growth - I mix one drop per gallon when rooting clones, and have experienced great success (but, I think my recent success is because of my new bubble-cloner, and not the SuperThrive alone) - IF you decide to use it, use it in weak solutions, as the instructions suggest - :smokin:

comatose plants do not sound good....damn Frank you've just popped my balloon. All those super claims on the bottle? So many that you need a magnifying glass to read them all? All because of pee? Thanks for destroying the world as I know it Frank.

I couldn't find my pH Down for a couple of days so I used Superthrive instead. The label says it's mostly acid, so I figured it probably wouldn't do much harm if used a few times - the "acid is acid" mentality.

Thanks for the advice, one and all.

I gotta say i agree with frank and stinky .I used to swear by superthrive although i to still use it in veg i have found that it hinders plants terribly in flower leading to fluffy buds and heavy growth stunt in some strains. Pharma can is right it works great as a ph down if your stuck ,Ive done this my self but wouldnt use it full term. i find that it works best early veg and rooting clones.I also use ro water and was finding it hard ajusting the cal mag from veg to flower but advanced nutrients have come up with sensi cal mag grow and bloom there research proved what i had been assuming that the plant uses differant ratios of cal mag in veg than it does in flower. tell me do any of you adjust cal mag from veg to flower.this product has sorted out a major headache for me.the postman.
