Should I start over?

[DoobieGrows]

They are about 5 weeks old. It's pretty much a science experiment at this point.

Ladies are all in pre flower. This one really took off the past couple of days.

I am kinda glad I didn't pull these up and start over. They have grown more in the past week than they did in the past 3 weeks .since I realized that I was mixing up my nutes in the wrong order.
They did start to pre flower tho.

I think you are really overthinking your nutrient mixing, but here’s a few tips about mixing nutrients and coco.
Coco:
You can overwater coco, but you figured that out already. Even with added drainage it’s easy to overwater baby plants. Keep coco just moist during the seedling phase, but never wet. When the leaves reach the edge of the pot and you see root tips poking through the pots you can start watering to runoff. Even once the plants reach this milestone they still probably won’t need water every day. You should not let coco dry out by more than 50% as a general rule, and once the roots are well established they can usually handle daily watering without getting stunted.

Coco has a very low base EC, but baby plants need very little nutrients. I start with a base water of .4 EC (r/o with calmag)and and I start my feed out at .6 for the first week and slowly increasing the EC into peak flowering. I top out between 1.3-1.5 EC with most cultivars. The nutrient companies and many growers will push that EC a lot further, and it may increase yields under ideal conditions, but more nutrients will not increase quality.

Mixing nutrients:
The PH of your nutrients will drift for the first 24ish hours after mixing, and more so if you are using RO water. RO water absorbs co2 which causes the he PH to drop. Adding buffers (calmag) and nutrients back to the water will bring the ph back up some and stabilize over about a day. For this reason it’s best to mix nutrients the day before use if possible to give the ph a chance to stabilize. If using tap water you will get some PH drift, but it will be less usually. 5.6 is a little to low, 5.8-6.2 is a good range to shoot for.

It’s a good practice to add buffers first, and then base nutrients, then supplements, but it really shouldn’t matter if your starting water is good quality, PH in good range and things are mixed in the correct ratios. Never mix components together, always add them to the nutrient solution. Silica, not silicone (similar but different) does raise PH, but that is fine as long as you understand the impact. Silica is good stuff you should definitely use it.

They guy who said they need more nitrogen is dead wrong. It looks like they are on the right track now, but it’s too much water and nutrients they were suffering from, not a lack of anything.

Glad things have turned around for you, good luck!

Yea I was definitely overthinking the mixing of my nutes. I also know it's Silica not silicon. Damn spellchecker lol. I was adding in concentrated ph up as my last ingredient because when I was just using the DynaGro Grow nutrients it drops the ph to 4.8.
So now I add the buffers before the nutrients and it has made a huge improvement. Thank you for taking the time to right.

I just realized I used Mg perlite to mix with my Canna Coco. And this garbage has a very small amount of Fertilizer and Nitrates. Wtf. I hope it doesn't cause any more problems. I did a flush 2 week's ago because the PPM on the runnoff was 1989ppm. And then everything was fine. But going over my numbers from this morning 1 was at 1100ppm. So tomorrow I am going to just give a small dose Cal/mag and see if if comes down to 600-700. Just when things are going good.

Girls are starting to grow like weeds. I am so happy that they are finally growing. If anyone is still paying attention here is how they look now. Most of the 's are on day 46. But the one un the top right corner is 32 days old. So I can tell I am getting better because the younger plant is almost the same size as the older ones .

What is a good PPFD at this point? I have my Hlg 600R hung at 36 inches from the canopy and it is only on 20-30%. The PPFD at the moment is 229 in the center 199 on the edges. I am wondering if I should lower it or increase the intensity or both? Please share your thoughts.

If you can get 400 to 600 in veg without lowering your lights try it over a few days and watch for stress..
600 to 900 in flowering.....
according to Dutch Passion supposedly.

@Dr Coughman is that a good wow or a bad wow? Lol
