plant mix in the same res.

I started with a Nirvana indoor mix pack of seeds.
UNK Types but their growing. this is a link to the actual jurnal for the grow I am having the issue with. I have a mix of indicas and sativas growing in the same res. I am wondering which is the more sensative plant. I am getting nute burn on 1 out of 3 plants. has anyone else done this and is it a problem that I am going to have to deal with? I am trying this DWC for the second time and not having much luck with it. I can only ask so many questions at the hydro shop.

Ok This is what I have come accross so far.
1) Plant Types: 2 diff Sativa and 1 Indica

2) 1 sativa #2 very touchy about Ph and amounts of Nutes.

3) in 2 months. Indica made it up to 8"
#1 Sativa made it to 18"
#2 Sativa made it to about 14"

4) I believe because of in balances in ph & nutes, it has pushed the 1 Sativa #2 Male. Indica It is not promissing either it is only 8" and showing that it may be Male as well. both were from nirvana indoor mix purchase.

Applied LST for controll in light and hieght.

What up JJ, hopefully this will give you some insight into whats going on! As mentioned in the other growjournal you had linked, it looks like a deficiency but if you are using the correct nutes and changing your reservoir every 3 days, that shouldn't be happening . Can you list on this page the nutrients (the doses), in addition to the pump / airstones you are using and a picture of the root system, in addition to pH measurements? Thanks man and don't hesitate to ask questions / lets get this fixed!

Well I'll try to get it all in here.
Up till the other day I was using 2 tsp. of Dynagro Growth in 4 gall of water. I just went to a 50/50 of dynagrow growth/bloom for flowering cycle. For the air pump I have a small 10 gal. fish tank pump. with 2-1" stones. Ph readings are going from about 6.5 down to about 4.5 in 4 days that is why I try to get to it in 3 days. day 3 read is about 5.0. pic of roots and leaves.

best to have too little nutes than too much and burn the other plants

I did cut back on 2 waterings. 3rd added drop more OK. went to full on next and did same thing over. just that strain of plant.

Hey JJ, so your plants definately look deficient, but surprisingly with such a small air pump you have a nice looking root system . I think that due to your situation, it might be best to do the following things:

1) change your feeding regimen so you get a nice healthy green on your plants
2) upgrade your pump / airstones to handle the bigger root systems you will encounter soon
3) teach you about pH'ing your solution

1 - So, while dynagrow is not a bad formula in itself, I think that the 3 part from General hydroponics may be your best bet because it has very easy feeding schedules to follow, while providing a good base nutrient for your plants. If you are looking for an even faster recovery, adding a vitamin additive in addition to foliar will help but let me know if you have the budget for that

2 - While your plants are looking 'relatively' healthy (not dying basically), the airstones and airpump you are mentioning will get you through earlier phases, but in order to maximize feeding, you need to put oxygen to your root system! Through my personal experience, I have found that buying small parts and then consistently replacing is too expensive, so these are parts I have found that work best and can be applied in many different applications so you won't have to buy anymore

3 - WELLLLLLL I sincerely hope that you are not replacing your nutrient solution whenever the pH drops below a certain level . That is why the hydroponic gods created acid and bass for us DWC growers who really need it for all the interactions in the solution. Whenever your plant absorbs food it is interaction with the solution and changing your pH (the exchange of ions in the solution and chemical byproducts / root secretions are primarily responsible). Instead of replacing your solution, use hydroponic specific acid and bass to get your pH solution around 5.7. This will make your plants nice and happy (and add acid and bass very slowly because fixing a mistake is harder than having to add a little more at a time). For this I recommend going to CVS or some pharmacy and getting baby droppers. It allows you to manage the solutions in the milliliters and be more accurate.

If you have any more questions don't hesitate to ask!

Ok, I would like to say thank you for the information on changes to my setup. I will look into the nutes later. I did look them up and they are sold were I go. I am going to a bigger pump just not that big. $$$.

I have sex out of one plant female. Sativa #1. (First female plant it only took 5 tries.)
not the one I was hoping for. the other 2 plants have me wondering. I am only going to give it 1 more week for my answer.

Ok so I am getting the sex of the last 2 plants 1and 1. with that comes an issue? do I keep it for the cross polination or put it for more weight? if I pull it how do I seperate it from the other 2. same res and roots grown together.

Yanking the males is TOUGH but once you have identified them you must pull them. There is no way I was able to get all the broken off male roots out because they were just too intertwined with the female roots. Just do your best, don't be afraid to cut out some of the female roots (they will survive) and I personally started using peroxide for insurance. On your first removal - good idea to drain the res and clean out ALL roots that have fallen in. A week later - take them out and look for any obvious "dead" roots, and again, if there are any in the res, empty it and get rid of them. Just do your best and the best advice - don't stress! Oh yeah and wash hands / sterilize equipment as much as possible - cleanliness is key.

On my next grow I am definitely spacing them farther apart for this very reason - I just hope I have gotten enough of the dead weight out. I will be pulling them up and visually checking on them from time to time.

Paper Towel Thanks for the info I will make sure I clean my knife. I am going to by a new lid and change my spacing next time. is there any thing that can be done in the bottom of the tank? dividers? Have to experiment.

nice birds nest you got there

I thought about dividers as well. Would definitely make life easier - though - probably somewhat tough to implement. Maybe some kind of hard plastic sheets + epoxy would do the trick. Make it removable. Set it on top of the air stones. Wouldn't eliminate tangles but I would think make them manageable. Once you cull the males you could get rid of it to let the roots grow out more. This would also inhibit the natural mixing action a bit so you'd definitely want to dilute additives like nutes, pH, etc. - which you should be doing anyway...
