Devil Cream® Hard Times

[JackOGreen]

Dear Community

I'm from Brazil and I'd like to say that is soooo hard to have true breeders seeds for this reason I'd like to ask help. This is a auto sweet seeds Devil Cream®.

I'm facing a nightmare with my beatiful lady.
She actually has 3 weeks and in last 4 days she is facing a lot of troubles.

Organic soil veg/bloom, 12Liter pot, Full biobizz products but at this moment using bioheaven, fishmix, recharge real growers weekly schedule and biogrow (1st time 3 days ago) all slightly less than the recommend dose.

LED QB301 120W. Grow indoor in white box 50x60x100cm (1.64ft x 1.96ft x 3.28ft. I use to dim the light 35% first 2 weeks and 50% 3rd week.

Soil ph (not too much reliable tool) = 7, run off 7.81.
Temp max 29C - 84,2F
Temp min 23C - 73,4
garden pro fan inline 125mm exchanging air
passive inlet air flow from outside
1 fan directed to bare wall
1 usb fan in the floor directed to pot bottom

I did not adjusted the pH due to use biobizz and after nutes addition ph down ~6.2.

Last Sunday, after lights off I spray the leaves with alg a mic and put in the pot the remaining with corrected ph 6.2 (I used ph down and checked).

Nothing worked so far and I am so so so sad! My best guess for root cause is high ph with Iron lockout. I also had some issues with watering, over I think, because in this new cycle I increased the size of pot and due to be auto flower I started with this 12L pot.

Any guess or opinion about the real issue here?

All the best and great harvest to all.

If that ph is accurate it's too high for soil or for hydro for that mater. For a soil grow you want your ph at about 6.5ph at the runoff. At 7.8 it's way too high and all the nutrients in the soil are being locked out from your plants. Each nutrient being locked out will have a different impact and with all locked out your plants will basically be dying off which is kind of how it looks. Also your temps are a little on the high side but not too bad and probably has little to no impact on what's happening. You need to get that ph down right away. I would suggest you accomplish this by lowering the ph of the water going in. You say before going in you have a ph of 7.0 and then 7.8 coming out, that means what is in your soil is rasing ph. That means you need to give water going in that is below 7.0. I would say try getting the water going in down to 6.2 and then see what it looks like coming out hopefully that will bring the runoff down to 6.5. If it's still higher then 6.5 then try dropping it down to 6.0 going in and see if that gets 6.5 coming out.

Because the plants are in the early stage of growth the main issue you're having is with nitrogen being locked out, that's why everything is turning a pale green to yellowish color and you're probably not getting much growth. Nitrogen is the main things that give your plants a healthy green color which is actually chlorophyll, without chlorophyll your plant can't convert the energy from the light into food for growth.

Okay I just read thru your post again and I missed the part about why you didn't adjust the ph but if that was your first feed 3 days ago. Are you saying the 7.0 and 7.8 is with just plain water? If that's the case and adding nutrients brought things down to 6.2 then your nutrients were probably locked out and then maybe started to get thru a bit but would get locked out the next time you used plain water. It needs to be in the 6.5 range every time you feed it whether it's just water or water and nutrients. So if the just water is 7.0 going in, adjust it down to 6.5 or lower if necessary every time you water. On days you add nutrients if the nutrients are bringing it down to 6.2 then on that day you can either leave it at 6.2 or bring it up to 6.5. The range for growing in soil is 6.3 to 6.8. Anything above or below that is not good although during veg growth you can probably get away with 6.2 because nitrogen doesn't get locked out on the low ph side until you get lower then that. I'll attach a graphic that shows the relationship between ph and nutrient availability that will hopefully help you visualize what's happening.

Hi HempKat thank you so much for your toughts.

I agree with your comments about pH as root cause. Thank you for sharing the chart, very clear.

About feeding I started (3 weeks ago) with recharge real growers, bioheaven, fishmix and germinated lentil tea for roots and the same for the next 2 weeks. On 3rd week I started with biogrow.

Both Biobizz and recharge inform that pH should not be an issue, specially recharge that raise a lot the pH after added, but about it supplier inform that after to be added on soil recharge, due to their onw characteristics, forms acid and reduce the soil ph properly.

Any way, even just with recharge, bioheaven, fishmix and lentil the run off raised a lot.
I'm wondering if my soil is not regulated, I purchased ready to be used and the information is that this soil is buffered on pH range 6-6.5.

I'm using the device attached and in top, middle and bottom of the pot, ph is 7.

Again, thank you so much for your time supporting me on this.

Best Regards

Those type of meters aren't the best to use but at least you're checking at multiple levels. Many just stick it in one place and feel that what the read there is the same thru out the soil. Even with multiple reading in multiple locations those meters aren't terrible accurate. What many use is a ph pen where you measure the liquid you add directly before you add it and then again when it drains out. With a good pen this tends to give you a better idea of the ph your plant is experiencing. Although to be fair many of these pens aren't completely accurate either. The more they cost the more accurate then tend to be because it's the accuracy you're really paying for. Anyway the advice I gave above was based more on this type of ph measuring device. No matter the device though the end goal is the same, get the ph down to 6.5 or there about and try to keep it there.

No need to feed using new organic soil for the first 4 to 6 weeks and that is your problem. When using new soil let the plant be and get adjusted before giving plant fertilizer. Too much plant food turned your plant yellow. When you start another plant again use a small dixie cup of fresh soil and as it grows just transplant it into a larger container. NO need to add food with the organic soil at first.

HempKat Creeperpark great insights. I think my issue is both pH and excessive food. Maybe due to extra food the soil balance is gone and this affected pH.

I will be easy on nutes next round... And let be heheheh good advice. My main goal is run full organic... learning journey so far.

Thank you for sharing some time helping me.

Your welcome, also most important when growing in organic mixes, is to always use pure water, like RO, or Rain to harmonize the microbe populations. Never tap water. The microbes will mine their own nutrients from the organic amendments in the mix when using pure water. Happy gardening.

Well first of all if you plan on eventually growing outdoors then good on you for going organic there's to much unnatural stuff going into the earth as it is, the last thing we need is someone adding more. That being said when it comes to indoor grows I don't particularly care whether a grower goes organic, chemical or somewhere in between. Chances are better then not I'm never going to be sharing any of your harvest so why should I try to force my preferences on you. That being said, and maybe you'll find some comfort in this, growing truly organic is probably the most complicated way to go and as such has a bit more of a learning curve. Not that it's rocket science or anything there is just more moving parts to it and more that the grower needs to think about and be aware of. I'm confident you'll get it all figured out soon enough and the good news is there is a ton of good solid information on organics from experienced organic growers, available on this website.
