I just transplanted my seedling into a 4 gal pot with coco coir that was pre moistened for the plant. She’s almost 2 weeks. I have not added nutes yet (i have ff and coco A & B nutes). Prior to transplant she was in a small cup, watered 2x daily, lights on 18/6 with the light 10" above leaves. She was stretching so I transplanted her to with the coco just below the first leaves (i have a hard time remembering the names of everything). Am I on the right path? Photos added for aid in giving me opinions.
*edit: there is a small amount of yellowing in the tip of my leaves.
Stretching is an indication of low light levels. Burying the stem is the fix as you’ve done.
Yellowing of leaves indicate it’s time to start feeding. If you don’t have already you need to procure a decent PH and TDS meter to aid in mixing/feeding.
I was going to wait for nutes until day 20, but when your hungry your hungry! As stated above I’ve got nutes ready to go. Any advice on how to mix, in what type of container and if nutes should be given daily. I’m growing in 100% coco so I’m assuming nutes will be given daily or ever other day?
I have a ph and tds in one meter. How do i use it correctly? Mix the nutes and test it with the meter, or just test the run off… both?
Once plant is established (decent root mass and canopy) you will be watering to runoff. Right now, not so much. It’s up to you to determine when media is dry enough to water.
Coco needs to be damp and once plant is established you’ll need to water daily to runoff. Usually about the time the canopy matches the diameter of the pot it’s in.
Mixing: you need cal mag. I also recommend silica. Both available by many brands. Silica is always mixed first, then cal mag, then base nutes. I have never seen any benefit from using the “Full Monty” of additives: base nutes with cal mag and silica is all you need to grow good plants. I mentioned meters: mix your nutes to 900 ppm total (including your water’s TDS). I use Homers for mixing as I do 5 gallons at a time. An aquarium wavemaker in the bucket can help mix nutes and keep the mix ‘sweet’ for a few days.
Once you have your mix and mix strength, add PH up or down as needed to stay between 5.3 and 5.8 (coco).
Once you transition to flower you could add a bloom booster like Beastie Bloomz or Liquid Kool Bloom. Bump TDS up to 1,100 to 1,200 ppm for flower. This is all dependent on adequate light.
First you need calibration and storage solution. Available on Amazon. Meters must remain calibrated and PH meter has to be stored in storage solution to avoid drift in readings or damage to the probe. Until you are watering to runoff (not yet), you will use to mix and adjust your nutrient level before watering.
Off to a good start, asking questions, getting excellent advice. So far, so good! Just keep doing what you are doing and use common sense when you get conflicting suggestions/advice(it will happen). Lots of good coco/hydro growers in here to help. I grow in soil so my advice is to follow @Myfriendis410 and others’ advice.
What gave you this idea?
It doesn’t look like any perlite was added. I always add 30 - 40% perlite so not sure how watering practice change by not adding perlite.
Cocco for cannabis is an excellent reference for coco growers. You would have found you need to start feeding once the seedling consumes its cotyledon leaves.
I’ve been feeding coco A & B daily ~1L daily. 100% coco. Water feed is pH 6.0, ppm 825. Light is at 60% ~12" (viparspectra 2000). Is this girl wanting more Nitrogen or could it be a little bit of burn from the light? The top leaves seem to be a little yellow in the middle getting a little darker green towards the edges.
Also any tips to lower feed pH?
Looks perfectly healthy…the lime green coloring is new growth. Your PPMs of 825 is good. In coco I feed the veg stage at 5.7-5.9, flower at 6.0. Are you feeding to ample run off? Looking good and my advice is to keep doing what you’re doing
@OGIncognito I have not yet. I’ve been watering until I can hear the coco take up no more water. I’ve been taking things slow this last week since transplanting her. I was afraid of drowning her. I’m new and a helicopter Mom. Thanks for the leaf info!
It’s almost impossible to over water in coco, but the plant takes up more water than nutrients so the EC in the root zone rises between waterings. In order to keep the root zone stable you can push out the old high EC water by watering with fresh nutrient solution until about 20 percent runoff. Many small watering events is better than one large one
I’m starting to realize that now. I feel like she was starving! I’m feeding her well, and just checked the run off pH- 5.5, ec- 2450, ppm-1220 / feeding water reading at pH- 5.6, ec- 1875, ppm-926. This is my first time, and Im learning, but those numbers going in and coming out seem weird. Are the numbers looking good to you guys?
The run-off is pretty high. This is due to the fact you had been feeding , but not to runoff. The EC of the root zone just kept climbing. Once you start watering to runoff it will even out. The in-flow is a little high, for early veg shoot for 1,100 to1,400 EC and pH 5.8. You want your runoff to be within 300 microsiemens of the in-going. And don’t worry about runoff pH just feed at 5.8 and you will be fine. I would water 2 times a day to runoff if possible.
What nutrient line did you go with?
Adding perlite to the coco helps with drainage, but it’s not the end Of the world you didn’t.
One more thing I don’t think was asked or covered. What is the EC of the plain water you are using for feeding? You will need to adjust for that as well.
thanks!
