Micro-nutrient / CaMg Deficiency?
smoke24answered grow question 4 years ago
You may have a light stress issue, I see the serrations on the leaves are starting to curl up a little bit. I've had this problem as well. Try either moving your light up or turning down the intensity, and see if you notice a difference in 3 days.

Hi I add cal / like to every food :-)
Best if you have osmosis water and mix the stale water for 24 hours (after 24 hours the chlorine has evaporated somewhat) to an Ec value of 0.2. Then add Cal / Mag until the Ec is 0.4. This is your source of water

Your running your ph a little high for soiless in the veg stage. 5.8 is ideal for what the plants want at this stage. You only need to add a little calmag if your using coco coir. Ppm should be 4 to 500 until they start to vigorously grow

My leaves are turning yellow, please help??There is yellowing in my leaves, my plants are 11 weeks old and they are on VEG, but the bottom has started to turn yellow. What is the reason? Could it be that 18 liters of soil in the pot is not enough???

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Suddenly, massive problems. Tried a lot already, nothing helped yet. Any ideas what I'm missing?Hey guys, I've been growing for a few years now and something like this has never happened to me. Long story short, as soon as I move my plants from the veggie box into the flower box, they slowly start showing these symptoms (see pictures).
The box worked fine for several grows

Seedling Light-burn or ToxicityHi growers!
Is this Light Burn, or nutrient toxicity from nutrient dense soil?
2 Mars Hydro TS600 lights at 27" from seedling.
PH 6.3 misting soil - RH is 75-80%. - Temp is 77F
No light meter, so I estimate PPFD is in acceptable range despite using 2 lights in 2x2 tent.
