lockout or deficiency in coco

[greenleaff]

hey all! so I'm having problems with my platinum do si do. All my other strains are doing good except this strain and its been having problems for a couple weeks now. 5ml/g calmag+, 4ml/g AN sensi coco a&b, 2ml/g rhino skin, sensizym, b-52. and .55 ml/g of root excelurator. and .6ml of mammoth p. Ec is 1.0/1.1. ph 5.7-6.1 it drifts up sometimes. temps are between 78-80. humidity between 50-60. My plan is to flush them tonight and then feed with half strength after then tomorrow 3/4 strength. please let me know! thanks

When this happens to my plants in coco, the first thing I adjust is the pH. I would adjust it to 6.2 or 6.3 and see how she reacts to that. That almost always solves my issues.

I am not familiar with your set up so excuse my ignorance but are you top or bottom feeding? Are you getting run off each time you water? It looks like you may have some type of drainage set up to get the runoff?

6.2 6.3 is high for calcium uptake isn't it? however, it won't hurt to try it. and yes its a top feed, and i drain to 10-20% run off each time and drains into the drain pipe (saucers have a tuber in the middle that connects to the drain pipe). I am changing out these emitters for a halo emitter because it drips "better". but i read on AN that if you use the Ph up and down that it can cause lockouts, and I have been using it to lower my Ph so Im going to cut that off.

That looks like major potassium deficiency and some mg-.. I'd feed 1ec of just the A&B base nutrient at 6ph for a couple feedings and leave all the other stuff out. Sensi coco shouldnt need that much calmag either I dont think.

was thinking of cutting out all the additives. also cut out calmag+ too? and you think i should flush tonight or just change the feeding.

are you using RO or tap water?
if RO, I would give it maybe 100ppm calmag TOPS, then 400ppm of the a&b.

If tap just bring it up to 500ppm with a&b.

water to 50-100% runoff for the first feeding. I wouldnt flush with plain water, rinse it with nutrient solution.

RO water. and 500 ppm with the 500 or 700 scale? my monitor can do both, just making sure were on same page ppm wise.

on the 500 scale. 1ec.

on the 500 scale. 1ec.

thank you!! i appreciate it!

From my very limited experience, Dirtbags advice is solid. I had problems early on and followed nearly identical advice and it worked like a charm. However, I did feed twice a day with at least 50% runoff for a couple days and then back to I've a day and bumping up nutes slightly with each day.

It's amazing what you can learn on here from these folks. I research like crazy, but it just doesn't compare to real-time feedback on this board.

Oh, and looking forward to updates with success!

I lurked in the shadows on these forums for nearly a decde before joining one when I finally became licensed to grow legally. I read them all, grasscity, IC, RIU and others.

The farm was the one which always had the most legit growers and least ego driven woo science imho. The respected posters were easy to spot and really know their shit. Even though I feel kinda like I joined after the hay day when people like seamaiden were posting regularly, i still feel like you will get the most down to earth honest advice from the most experienced growers here.

Another recommendation,.. Kinda funny since I was reding a thread about this just this morning by @Jimster, since it looks like you have a magnesium deficiency I would mix 1/4tsp Epsom salt into 1L of RO in a spray bottle and foliar feed every other day in the morning for 2-3 feedings.

I think your Mg uptake problem was probably too much calcium in the nutrient. Even though there is tons of mg in the solution, too high a total concentration of calcium inhibits its uptake. Same thing happens with people taking too much calcium, you can run Into magnesium deficiency.
A good nutrient solution is just like a good diet, it's all about balance and correct ratios. And just like food combining, knowing how different nutrients interact with each other.

All of your numbers look good. You don’t mention how often you water. Not watering at least daily in coco is the # 1 cause of most problems I see when people are having problems in coco. Plants that size will probably need twice a day fertigation. Also from personal experience, do not add pH adjusters to AN “pH perfect” nutes. If the final pH of your mix is anywhere between 4-8, you’re good. Adding pH adjusters will mess with the chemistry and cause problems. I switched from AN nutes for this very reason. They are marketed to new growers who don’t have the knowledge or the equipment to correct pH.

Seen a lot of similar posts about fucking with ph perfect. All answers pointed to fucking with the ph equals bad things will happen. Never used it but I hate it already from all the stuff I have read on people's experience with it. The only time people have had good experiences is throwing blinders on and that concept is so foreign to me I could never use it.

Also from everything I have read designed for RO and no cal mag should be used. Never used these nutes but I'm betting if you use RO and nothing else but the nutes and feed as @Enforcer suggested your problems will go away.

Week later. I called advanced and they said I was putting too much cal mag because Sensi Coco already has cal mag (which I had no idea of). Which caused lock out. So they told me cut cal mag off and raise my EC. My EC is at 1.0 for these guys right now of just Sensi a & b, and the additives. The length between nodes are short, leaves are droopy, i honestly don’t know if they’re getting better or not. Going to wait another week to decide to pitch them or not so I can fill their spots with other plants.
And the last pic of the single leaf was from one of my other plants which is healthy but seems to want more magnesium.

Yep same thing I see everywhere on this nute line. Put it in the water and nothing else... Don't bother phing or adding anything else. Just walk the fuck away and it seems to be ok.

Not my cup of tea and probably not the best line of nutes to use IMO but hey some people love it

The advice on this site is getting worst by the day.
When your new to growing you need to start with base. Additives do NOT need to be added everytime and they should only be added when plants are healthy. Those plants are probally trash now, even if they recover they will be to big for your space.
Stick with your base nute and watch how they grow, learn how hey grow. And do not let the coco dry out ever once the roots are established.

This is how healthy happy plants look in coco.

They love it because of the flashy name additives and pretty labels. Marketing gimmick that just sucks every newb out there in believing they need all those products every watering to have happy plants.
Same goes for dispensary weed, it’s the labels and hype that makes people feel special when they buy it.

It's marketing just like anything else. Of course they're going to try and sell you things you done need. If even go as far as saying feedingthe schedules are created by the manufacturer are also designed for you to use more nutrients and buy more product.

As being new to this I am still aware and that's one of the reasons why this forum is so great. You learn from other people's experiences.

I'm not sure if be going down that pH Perfect line anytime soon. It also seems like anything that's a shortcut means you're selling yourself short. Might as well go the extra mile and harvest the benefits.
