Help please. Leaves all turning yellow.

[Desmondg]

Hey everyone. All my leaves on one of my plants are turning yellow. Don’t know why?
organic soil
Tap water and remo bloom
600w HPS
Temp 24 Celsius lights on and down to 18 Celsius lights off
Humidity 40-50%
Day 33ish in flower.

 

[Gwhiliker]

are you checking ph?

 

[Gwhiliker]

also look a little hungry
could be due to off ph letting them not feed correctly

 

[BanjoPu$$ywhistle]

Whats your input water pH and ppm level?

 

[Gwhiliker]

should be going in around 6-6.5 ph and 800-1000ish ppm 33 days into flower she needs a good amount of p and k not as much n

 

[BanjoPu$$ywhistle]

Seems spot on, maybe salt accumulation? Did you do a pre flower flush? I would check your run off ph and ppm. If thats not messed up then I would say you just have hungry plants that need another 300-500ppm of NPK.

 

[Gwhiliker]

one way or another they arent getting the food they need

Are you just using the Remo Bloom? That's a 3 part nutrient and you need to use the micro as well during both veg and bloom. I looked them up and the calcium is in the micro. If you're using just the bloom then you're missing nutrients including nitrogen which the bloom is lacking as well.

Its a myth to starve plants of Nitrogen during flowering. All Nitrogen is, is Protein. For an 8 weeks flowering strain Nitrogen should be slightly increased every week until week 6. Actually Everything should be increased. Mg should be increased in weeks 4-6 Then the last 2 weeks everything should be cut back, but never totally restrict any element.

Ph of water last feed was 6.8. That was with just the bloom. I don’t have a PPM meter but will get one right away.

Yes only using bloom. I have the kelp from Remo as well but only used it once to make a tea thingy for them. So what else should I be adding to help them out?

I have been using the bloom nutes on the lower dose as well well. Been too afraid to give them too much. Organic soil and all I thought I only needed to give tap water.

 

[Desmondg]

So I need to be adding some more types of nutes. But any suggestions on which one? My local store has the remo line and the cyco as well. Thanks and sorry. Newbie at this.

 

[Desmondg]

Would cal/mag from GH help? I have a bottle of that here

 

[Gwhiliker]

u should be using micro and gro as well GH has a 3 part flora series that works great for beginners!

The bloom doesn't have everything in it. The way their 3 part is intended to be used is micro + grow for veg and micro + bloom for flower. At this point it's too late to really do anything. But in the future you'll want to use the micro in combination with the grow. I can't find the exact list of ingredients in the bloom but what I did find didn't mention calcium, magnesium, or sulfur which is most likely in the micro in the form of magnesium sulfate and some form of calcium.

Remo’s Bloom contains 1-4-6 base NPK as well as boron, chelated copper, chelated manganese, molybdenum, and chelated zinc.

And I don't understand how you're trying to grow. You mention organic soil and that your making tea. Remo nutrients are synthetic so you're not doing an organic grow.

Since you're already using the Remo just get a bottle of their grow and micro. Use the micro and grow in veg and switch to micro and bloom in flower.

It doesn't really matter what brand of nutrient you use since they're all basically the same. Just different names and different bottles but basically the same ingredients. As long as you're feeding everything the plant needs which you're not by just using the bloom your plants should grow happy and healthy.

Guess I’m really messing this grow up . Ok so I got the micro and will use that with the bloom at the next feeding which should be tomorrow. I also got a tds /ppm meter so I will check my water tomorrow as well before I start adding anything. Never used a PPM meter before so off to the YouTube videos I go. From what I understand is I start with a base point from what my water is by itself and then I will need to add the nutes to get my desired ppm? Then check ph and use up or down as needed? Sound right?

Sounds about right. You couldn't snap a picture of the bloom ingredients could you? I'm curious as to what exactly is in it.

And even though your grow wasn't the best and your yield will suffer the weed will likely be better quality than if you had overfed them as many do.

For sure. Here is the bloom and I also have a bottle of the kelp.

So there feeding schedule says 10ml / gallon of each for week 5,6,7 Does this mean that I would be adding a total of 30ml of nutes to 1 gallon of water? Or is that what I will be figuring out with the PPM tester?
