GhettoStylestarted grow question 9 months ago
Light ice at a distance of 50cm shines at 23 DLI humidity and temperature are all normal!
According to nutrition, water in solution (0.2 EC) + Canna Aqua VEG(0,8 EC) = total EC =1.0 pH 6,0

Hey Budy,
I might see a few things which popping up to check:
-Calcium and Magnesium Uptake:
Coco coir can sometimes have lower levels of naturally available calcium and magnesium. These elements are crucial for preventing yellowing, especially at leaf margins.
--> Add a calcium and magnesium supplement specifically formulated for coco coir to your nutrient solution. This can help prevent deficiencies and improve overall plant health.
-Nutrient Solution and pH:
Hydroponic systems, including coco coir, can be sensitive to pH fluctuations. Incorrect pH levels can hinder nutrient uptake, leading to yellowing.
--> Maintain a slightly higher pH range, around 5.8-6.2, for coco coir. Regularly monitor and adjust the pH of your nutrient solution to ensure optimal nutrient availability.
-EC Levels and Nutrient Uptake:
Coco coir typically requires a higher EC compared to soil due to its inert nature. An EC of 1.0 might be on the lower side for coco.
--> Gradually increase the EC of your nutrient solution to provide sufficient nutrients for your plants. Monitor their response and adjust as needed.
Nice grow so far buddy - keep it going :)
If you got further questions feel free to follow and hit me up in DMs.
All the best and good luck !!

Total EC 1.0 is approximately 700ppm. It is way too high for this size of plant.
You should be somewhere around 400ppm actually.
This is why your plants are burning.

Heres a feed guide for hydro.
From the day they pop you give 400 ppm 0.8 ec if their photos. 200 ppm 0.4 if their autos. Each week increase their feed by 100 ppm if your seeing good growth. Stop when you reach 800 ppm 1.6 ec for photos and 600 to 650 ppm for autos. Only give more if they really need it. Not sure what week your at now so just go from when they sprouted 400 ppm for photos, so if their 3 weeks they should be at 600 ppm 1.2 ec and if their autos they should be at 400 ppm 0.8 ec

I added mycorrhiza to the coco coir from a local store. It turned out that there is slow release fertilizers in it. Was not indicated on the packaging.Please Help!
First time after watering with 5.7pH 400ppm drainage water was 6.7pH and 800ppm. I flushed her to 400ppm.
Yesterday was the second watering (450ppm, 5.7pH) and drain was 700ppm 6.7pH. I flushed her to 460ppm (1.5l of water), but pH still 6.6

Big difference in first true leaves' sizeBig difference in first true leaves' size
Its almost day 5 after emergence. Is this normal? Should I be concerned?
ALSO: It's still a seedling but, I maybe think the cup in which i'm growing it in is too small, or rather I put too little soil (9cm diameter , 4cm tall dirt).

Questions about wateringI created a 40 ml solution, the instructions say to transplant after the sprout has grown to the top of the plastic cover and the roots are visible through the plug. The question is, is 40 ml of liquid enough for this growth? I think not.

3 days in, only cotydelons with no sign of the first true leaves. Have you seen this and has it recovered?This plant was stunted at the start after he couldn't get his hat off, but now looks pretty healthy however it's been 3 days of just cotydelons and absolutely no sign of the first true leaves. Have you had this before and did it recover to eventually grow true leaves?

First Grow 4 weeks into Veg - Let my humidity get too high for 1 night. Need help with mold/septoria/?Last 3 days I've pruned diseased leaves every morning, foliar sprayed peroxide leaves & topsoil, & added some to watering solution. Is only affecting one plant in tent. Humidity no longer issue (was waiting 4 inline fan). If I keep pulling off leaves it's going to die anyway.
