Indoor Squid's Second Grow-Duurty Dragon, Diesel Ryder & MI5

[The Squid]

Sulfer def will start from the backside of the leaf towards the front. Looks very similar to what you have going
On here. Also your not over watering again are you? They look a little soaked for a seedling. Just my bro. Hope someone else chimes in. I've never used diamond black or the other and also never fed a seedling so someone else may have better experience with that.

Ok so I guess the sulfur is a possibility. Anything to do or just ride it out? No I don't believe I am over watering. I get differing opinions on when to start full waterings so I just took that I made my own decision. I was giving small amounts and sprays until a couples days ago when they all had two sets of true leaves. I did a full watering with 10% runoff. It's an 18 oz cup and multiples roots are in the bottoms of every one. Two days later they were dried up, especially the MI5s. So I don't think it's that, they are drinking faster and faster.

I don't think any of this is that bad I just wanted to ask. I guess I will stop doing the Bio Root/DB soak before I plant even though it's a really light dose, I guess the Promix has just enough starter nutes to do the job well. Also gonna stop adding sulfur too. I really think this bag of Promix is just a little off really. I water with a little over 7ph plain water and it still comes out real low 6s, and with no sulfur or anything. I did other tests. Oh well, like I said my ph has been fantastic the whole time from the get go so I am sure I'll be just fine in the long run.

Any other suggestions are welcome though, Cap'n. Thanks man And thank you Growbewan, too. Have fun with the fam.

@JM> I added a pinch of powdered sulfur to the cups mix to lower the ph a little, but I don't think it needs it. So if anything I think Captain is referring to a Sulfur toxicity. Magnesium? I just wouldn't think it would have any deficiencies this early. Day 9.

 

[JM]

ahhh ... sulfur toxicity... maybe.... i was thinking he meant def....

you'd be surprised how fast some strains get agnsty for MG... but promix has some lime in it... so as long as ph is good its good....

btw... you said ph out at 6.0 thats your issue....



at 6.0 molybdenum, iron, and boron are all thats available...

 

[The Squid]

Sorry JM, should have explained better. The runoffs at a little above 6 ph that I mentioned were on some tests I did separately after first watering. But after a few days, and the lime kicks in and another watering it is right on at 6.3 +/-. Which is right where Promix should be. I had just heard that Promix is around 7 out of the bag, but mine is lower for whatever reason.

My feeds have been 6.44-6.55 and runoffs have been 6.15-6.35 the whole time. I have been told that 6-6.5 for promix is where I want to be, so I should be fine there.

 

[JM]

yeah... especially young you should stay a hair higher... mossy and i have noticed a little better germ rates starting plain 7.0 water and soil... then after germ... about 5-7 day a 1/4 strength grow feed... then 14 again at 1/2 etc etc....

runoffs have been 6.15-6.35

look close at that chart and see where your nutrient supply is dipping out on the low end?

just tryin to dial you in another milli-notch ...

 

[Captain cure]

Yea I don't have a good pic of sulfur on hand but if you find one it looks very close to what you have going on. You would be surprised at how easily some strains especially seedlings will react even to a light feeding. Overall they look good but it is something to look into for now and future reference.

Nevermind i found a pic. Its a little older of a plant but youll catch the drift. Give me a couple mins and ill see if i can post it.

 

[The Squid]

Gotcha guys. Much thanks. By the way the one that Muddy said was bleaching isn't one of those two new ones above. That one was an MI5 a couple pages back. This all makes sense though, however small, they are indeed young seedlings and can only take so much.

@JM> Man that seems early for feeding. Day 5-7? I know I know, I'm questioning you and Mossy, haha. Just making sure. And that chart is for soil and hydro, Promix is supposed to be right in between so it's hard to say. If I were in soil then yes, I'd be a little low but as far as what I have read and been told I am fine above 6 and below 6.5. And I am more towards 6.5.

 

[JM]

day 5-7 after cotyledons open.... i mean....

and treat promix like soil.... I've even had it run up to 6.8 with no issues.... i find on my ph meter (soil one) its almost always dead nuts at 6.8

I use my nutes to start tweaking (resident) ph.... i mean when you water the ph of that helps buffer it down.... hard to explain....

but say... my first nute watering... with my water and nutes... falls on 6.4-6.5..... as i up the nutes as it progresses my nutes help hold the ph down.... i start dumping down as they mature... till at 3-4 weeks i'm dumping 5.7 - 6.0 nute layden water on em... and that usally hits my soil ph meter after an hour or so in the soil at 6.5 ish..... hope this helps....

 

[The Squid]

No I see what you mean. The nutes lower the ph and help buffer. And alright 5-7 after cotyledons. So like 12-14, right. And alright on the ph. I will bump it up a little and see how it goes. I just have to do both and see what works best. It's just the majority of what I have read is treat Promix like semi-soilless, so 6.3, but I'll still bring it up a little. I know that the soil.promix h raises slowly as it dries back to the original medium ph without water. Like you feed at 6 or so like you say and it gradually makes it's way back up. I got that.

I will raise my feeds a little and keep a close eye or three out and be on top of when they need needs. Today is day 9 so maybe I can give their first veg nute light feeding on Tuesday day 13. maybe even Monday. Thanks for all the help guys!

 

[JM]

yeah, you're pickin up what im puttin down...

I know that the soil.promix h raises slowly as it dries back to the original medium ph without water

exactly... so you see how to regulate it by watering / feeding .. remember between feedings you can always hit it with a properly buffered water... like a 6.3 or even a 6.0 water... to keep in the "zone"

of course... taking special care to allow enough drying of the soil but not too much to hurt the plants....

Cool, yeah I've got how all that works. Still tweaking my skills of watering really well, but I think I have been doing well using the weight and being able to check the moisture at the bottom of the cups when using two cups like one uses with the tier method. I think they are about ready to transplant by the way the roots are in the bottom of the cups, but I only have 6 Airpots and I need those for females that are staying in the tent. The males will be put into a bigger container just not the Airpots. But I don't want to stunt or root ball them, I don't think it's gotten to that point though they aren't just going crazy out of the bottom or anything just multiple are visible is all.
