Father & Sons Perpetual Hydro Grow In Aqua Farms

[cannasensei]

Looking heavy in there

 

[DrTentgrow]

Here is a vent me and my Dad made, we replaced the glass in a small window near the vegging room with a panel which we jigsawed a hole out of so we could direct the extracted air out side.

looks like that could be a sulfur derfficiency the pics in this link look simillar just further along.

Xlr8 is the best guy I know to ask about defficiencies though

 

[DrTentgrow]

Hello cannasensei i don't think it's mag as we are using cal/mag+ to build the e.c up to 2.0 then using vita link plant start to knock it up to 1.1 so there should be enough mag in the 2 of those for such little plants?

 

[cannasensei]

Then I'd have to agree with Jon there. That should be plenty calmag for em

 

[DrTentgrow]

Also since we noticed the yellowing we changed the reservoirs and upped the food from 0.8 to 1.1 (2 days ago)

 

[DrTentgrow]

Shouldn't they be getting enough sulfur from the starter feed?

 

[cannasensei]

Not necessarily. Some strains like more than others. U can monitor it the next few days and see how it progresses. May help u get a better idea of what's going on then

 

[DrTentgrow]

Yeah that sounds like a good idea, i will get the starter feed bottle down tomorrow and check the label to see just how much sulfur there is.

 

[DrTentgrow]

I think we worked out what the problem was, we only put cal/mag+ and full strength rhizotonic in the 1st reservoirs because the was still background ec coming from the pebbles where we had rinsed them in tap water and soaked them in 1/4 feed veg nutes (ph 5.5) we wern't sure exactly where the ec was coming from but assumed it must have retained some food enough to keep them going for a week or so but i don't think it was, the yellowing started before we changed the reservoirs to a solution with more feed in so hopefully the problem should sort it's self out.

If it is sulfur deficiency does any one know how quickly it will sort it's self out and if the yellowing will green up?

 

[jon705]

Ive never had it so i cant say but the leaves wont get better.if you fixed the problem it wont start happening to other leaves.

 

[DrTentgrow]

I thought sulfur was a mobile nutrient? wouldn't that mean it can repair yellowed leaves? i may be wrong.

 

[jon705]

they might if they're just yellowed a bit ive never had a sulfur deff so cant say for sure ive had other defficiencies like cal/mag and they dont fix themselves they usually stay the same or get worse even if the problem is fixed.just my 2 cents though

 

[DrTentgrow]

Ok cheers mate, tomorrow i think we will change the reservoirs and start using vegging nutes instead of starter nutes, our vegging nutrients are designed for osmosis water so shouldn't have to add any cal/mag just rhizotonic we will make the ec 1.2 this should sort out any deficiency's. I hope the deficiency what ever it is doesn't stunt them much.

 

[DrTentgrow]

jon705, my mistake sulfur is immobile .

 

[cannasensei]

yes sir.

 

[DrTentgrow]

We have sorted the sulfur deficiency and the leaves did green up, the only trace it left was some small brown spots that look like nute burn but isn't. We are checking the ph and e.c every day and topping up as needed, we have stopped using the vita link plant starter nutrients and have started using ferro's vegging nutrients at a e.c of 1.2 we are also using rhizotonic bringing it up to 1.3. Every time the e.c climbs to 1.4 we add a liter of plain osmosis water knocking it back to 1.3 they are doing very well i can't believe how much they have grown in the last week.

 

[DrTentgrow]

One week of growth!!

Looking good DrT

Hello DrT am subbed for this one . I use waterfarm kits in 5 gallon pails with an 8" netpot lids & get trees [using aproximately 3.5 gallons of water / 14liters] am dying to see what 45 liter containers do ! , as a side note I use GH floranova bloom solely start to finish & have had huge success since combining the two no matter what strain I'm running , your girls look great & good luck !
