Ph of Pro mix before planting newly germinated seeds

Helps a lot thank you I think it could come up a little more. I’m in there often anyway.

You want to keep light as close as possible. You are now doing that. Make sure to check warmth on back of hand daily to insure you do not start to burn leaves.

My biggest concern is that you are going to fry them with all the nutrint additive you are applying to your seedlings.

No nutrients should be applied until you see at least 4-5 true sets of leaves!

I have read more about not feeding this soon but with my first attempt the seedlings were yellowing. Then my local grow store mentioned that promix has no nutrients. I’ve read that seedlings have a little to go on by themselves. The soil was quite wet when I fed 'em and I used only one quarter gallon on all six. The grow formula is 2-.25-1.5, ancient Amber is 0.1-0-0, and Trinity is 0.1-0.5-0.25. Still learning. Let’s hope I haven’t doomed them already. This morning leaflets have laid down a little and marked growth of the next node. Color looks good.

I did bury the germinated seeds very shallow. Less than 1/4 inch. I have gently piled medium around the stalk. Almost half way up. Didn’t want to rot and kill 'em though before new roots have a chance to grow from the stalk I buried .

Lakewood, thank you for monitoring. This community has brought a new excitement to my medicinal hobby.

Actually; The ingredients of ProMix do provide the necessary minerals needed to sustain seedlings. This is why it is the choice of professionals all over the world.

You never give seedlings nutrients! Period.

Huh, OK. My local store had me convinced that the dolomite lime , peat… wait I just may have caught a clue. I think I read in one of Mr.Ron B’s e-mails that a young seedling has enough food for a time. (How long technically) So maybe the fact that I started adding ph down to the water since the first watering. My local store sent me home with some ph strips and didn’t tell me that with those you need

“a buffered solution” or use their Lo ion kit. Don’t even know what that means but when I got drops my drainage was in the 4’s for ph. I ran many gallons of tap water( oops fresh from the tap) through all the plants to flush.oh, I had been using Dyna Grow with the down. I bought drops to test ph and a hug of roots organics and they came back. Flushing is a miracle. Maybe my little ones were just starving because the ph was so low. Ding ! I may have just learned something. I’ll be sure to like your post latewood

PS I still have only fed them one time and it was weak. Uploading… They are looking OK this morning. Maybe growing a little slow. ? Hopefully this pic will finish uploading. I have turned on the other 400 MH to keep a stable temp. Stable now is 75-77 . They are under only one but getting more reflectively.

Thank you for checking in with me.

I’d like you to take a peek at their feeding schedule and tell me what you think if the internet speed will finish with the last pic I’m sending you.

Is it bad to have seedling in soil ? Soil has lots of composted nutes in there.

I used soil for my second try and they almost died on me . They were clones that came to me already in roots organics soil laced with fungus nats.

Hi, I use Dutch pro mix it is soilless. It contains 2 types of peat and perlite so its PH is 5.8. It helps your seedlings. When your plant pops up you will see 2 small leaves these are called Cotyledons when they turn yellow your plant needs food. Hope this helps.

Take care.

David.

I put this pic up for you if you click on it it should enlarge it then you will see the 2 small leaves at the bottom.

I just RE read an old post of yours about allowing the ph to swing a little. That post makes lots of sense. Hey, I’ve got roots coming out the bottom of my one gallon pots with promix in them. Should I be feeding them ? Keep in mind they are in a room with two 400 metal halide. The most advanced girl I fed last night just to make sure it wasn’t going to kill 'em.

I am following the feeding schedule , (not intentionally), but it seems to be what they need.

Even told me to apply nitro bat so I used a sprayer to soak it in before I fed with non ph’ed solution I now have a 6.0 ph for runoff. Just as Mr.Ron B. Said in one of his e-mails. Eureka! No ph buffering chemicals. Just what I was hoping for. Hope I can keep it that way.

David, I reread your post about when seedlings need food. Thank you, that’s good info. I have stared at them thinking that ( before the Lab) I’ve heard those where the food banks for seedlings. Now you have settled that thought.

Well, I’m in a soilless medium, yet I’m still cringing a little. I’ve read one guy put his seedling in a dwc bucket as soon as he saw roots from his peat starter. I see roots at the bottom of one gallon pots.Did the seedling go into the dwc too soon ?

Hi, I have never used dwc so I cant really comment but I am sure someone will help you.

Take care.

David.

PS the pic is of my latest Gold Leaf she is 3 weeks old.

rjw716d,

Looking at the last picture you posted here; These seedlings are not ready to take up nutrients. You need 4-5 true sets of alternating leaves before you start applying nutrients.

At the stage you are at; I I water with Liquid Karma. 1 TBS. per gallon of water.

I don’t see how those little seedlings are growing roots out of the bottom but, I will take your word for it. Just make sure that the protruding roots are kept hidden from the light. I would not advise transplanting at this time due to the small size of the seedlings.

Looking pretty good so far. Be patient. :slight_smile:
