PBP in flood tables, questions...

[anferneybra]

Greetings,

For years now I have grown in flood tables and ebb/flow systems with great success with all sorts of strains. I have used GH 3 part with some SM90 thats it, great yields and plants couldn't be happier. As of recent I have teamed up with another grower with limited experience, and she uses PBP botanicare line.

She is having major issues in flower, and I dont know enough about the line to diagnose the problems. They make it about a week into flower and then turn yellow, spotty and overall unhappy.

I see that botanicare runs a 1 part grow, bloom and then pro soil chart, with a wide array of additives. She goes by the chart, with calmag and liquid karma as her additives.

Im reading her mixes at over 2.6EC and sometimes the PH after making a new batch of bloom is as low as 5.0PH The ph swings up after a couple waterings but the ppm is super high. She is using the full ML dosage on the chart even when at the bottom it says to reduce the fertilizer by 10-25% when using additives. Her reservoirs also have nutrients that look like they are seperating and turning the tables a nasty ass brown.

My question is for anyone experienced with botanicare in a hydroponic setup using a 3inch rockwool cube in a 1gal hydroton container.

What do you run per gallon of what?

Also, why would you use something called "pro soil" in a hydroponic environment? It seems that its nasty and turning everything brown...can you just run PBPbloom instead of pro soil?

I know there is probably no short answer but im trying to get through to her that she is running way too hot in the nutrients.

As a sample of what she runs is like week 4 flower=
20ml/gal PBPbloom
5ml/gal cal mag
10ml/gal liquid karma
3ml/gal SM90

Thanks for any info or advice anyone with experience with this line has!

Definitely sounds too hot. The brown crap could be the liquid karma, i would try running just 7ml bloom, 7ml veg, 0-5 ml cal mag depending on how hard the water is and go from there.

I use PBP grow/bloom with canna PK13/14 im not in tables but your her results should be same or better. This is all she needs. LQ will strain your roots keep that in mind. It wont hurt anything it just mas at all look like ass. 2.6 seems hight to me? PH is low should be 5.8.

I use 20ml per g when in flower of Bloom. Then PK 13/14 IS 6ml per g(EC2.0 MAX) into my res mixed with a pump. Adjust the PH to 5.8 ///// I would take the res and clean it very good mix a new batch PH should not be swing like that. Mine is stable.


PBP has a line for hydro setups. You dont want the soil version. What she is using is ok just back off on the doses untill you get to EC2.0 and PH of 5.8-6.2.

in my experience plants on flood tables like to start with ferts at about 1/2 strength to start 3/4 for the second res change then full strength from there on.
good deep floods encourage root growth throughout the media not just at the bottom also speed matters the quicker the table fills/drains the better
aerate the fuck out of the res the more air the better i recommend air stones over mag drive circulation pumps as the mag drives may cause the iron in the nutes to fall out of suspension

I ran this exact set up for over 2 years. The biggest problem is mid-late flower as you pointed out. Here are some of the changes i made to the profile over time, they should help. (btw Floralicious + is the only product change i would make, just wait till you run out of the LK.)

16-18 ml pbp bloom
8-9 ml cal-mag
1.5 ml sm-90
1-2 g epsom
1 ml floralicous +

That profile is DIALED trust me.

thanks for the great info guys, its much appreciated!

Just to be clear, you wouldnt rec. using PBP pro soil EVER in hydro? just the veg and bloom?

thanks for the info!

Hello.

PBP has 2 different bloom formulas.

PBP Bloom has more N and less P than PBP Soil.

PBP soil has less N and more P than PBP Bloom.

They have you starting with the PBP Bloom to keep the N levels higher in beg flower....then switching to PBP Soil for last 4 weeks to keep P levels up with lower N levels.

PBP is the shit. I use it in DWC sometimes.

I never run more than 10mL/gallon of Gro or Blooms....always 5-10mL Karma, 5 ml Cal Mag and definitely don't miss out on Aquashield for the roots and Hydroplex for the shoots. Hydroplex is Botanicares bloom booster and its the shit IMO.

Grow hard.
