Hi, I would check the plant's drain during the grow from time to time. Measure the pH value and the conductivity there. The conductivity should be a maximum of 500 - 1000 µS above that of your watering water, and the pH value shouldn't deviate too much from that of the watering water and should, of course, be within the parameters (min. 5.8 - max. 6.8). Otherwise, flush it well with distilled or osmosis water until the desired values are reached. Ideally, the conductivity should even be lower, then targeted fertilization will be effective again. Hope it helps in the next grow. Cheers and have fun gardening!

N Ca K mb Mg deficiency

Calcium deficiency. Quickly add calcium to your diet. Merry Christmas and a prosperous New Year!

After looking through your diary, I see you've never added a calmag supplement during your grow. I would start using calmag, most liquid calmag is used at 5 ml/gal for most of the grow. I also see that you just started flowering and changed to bloom nutes. The first couple weeks of flowering is a transition period and the plant needs just as much grow nutrients as it did during veg, the plant is going through a lot of vegetative growth during the stretch and is why you don't want to switch to bloom nutrients yet. I actually add more grow nutrients during these couple weeks and then decrease after the stretch.

I would also say that you have a pH problem. It looks like it can't absorb the nutrients correctly. How much CalMag are you giving? I give 2ml per liter of watering (with LED!!!) and then it works for me. Before, I always gave a max of 1.6ml and it was always too little.

Looks like a deficiency but also an excess. The leaves are light due to a likely N and CalMag deficiency, but in some places, there are burns that could indicate a nutrient blockage. What EC and pH are the plants being watered with? It's possible that you're giving them enough nutrients, but they're not being absorbed properly because the pH level is off.

CalMg Problem

CaMg or N deficiency. Feed CaMg first . Make sure to mix it with the water before adding other nuteients.

Calcium deficiency...........quite simple.....nothing more, nothing less. Add a cal/mag supplement to your fertiliser line up, or increase the dosage if already using one. The old, damaged leaves will not recover, but it will stop the problem from getting more advanced, with the new growths showing no symptoms.

Hello, It seems like you're worried about a plant showing signs of stress. There are several possible causes for the spots and pale color on your plant's leaves. Here are some possibilities: 1. Nutrient Deficiency: Nitrogen Deficiency: This is a common cause of light green or yellow leaves. In severe cases, the leaves can turn completely yellow and eventually fall off. Magnesium Deficiency: This can lead to yellowing between the leaf veins, while the veins themselves remain green. Iron Deficiency: This can also cause yellowing between the leaf veins, while the veins themselves stay green. 2. Pests and Diseases: Powdery Mildew: This fungal disease causes a white, powdery coating on the leaves. Spider Mites: These tiny pests suck the sap from the leaves, causing them to turn yellow and fall off. Leaf Spot Diseases: These fungal diseases cause spots on the leaves that can vary in color and size. 3. Environmental Factors: Overwatering: Overwatering can lead to root rot, which can cause the leaves to turn yellow and fall off. Drought: Drought can also lead to yellowing and leaf drop. Temperature Extremes: Both heat and cold can stress the plant and cause leaf damage. To determine the exact cause of the problem, you'll need to examine the plant more closely. Look for signs of pests, diseases, or nutrient deficiencies. You can also check the soil moisture and temperature. Once you've identified the cause of the problem, you can take steps to fix it. For example, if the issue is due to a nutrient deficiency, you can fertilize the plant with the appropriate nutrients. If the problem is due to pests or diseases, you can treat the plant with a suitable pesticide or fungicide. If you're unsure about the cause of the problem, you can reach out to a local gardening expert or take a plant sample to a local nursery or garden center for diagnosis. Merry Christmas, buddy.

Hey, your plant is lacking calcium and magnesium, which is why you're seeing the brown spots and the light/yellow color between the leaf veins. CalMag feed, especially in late veg/early flower! Best regards!

Hey there don't worry that'd anneasy fix 1st I'd check the ph if the run off water that comes out the bottom of the pot Seems like a slight ph problem Also seems like you have slight deficiency the leafs don't look very lively. So personal I would not take any action right now what you seem really isn't that big a deal especially being so close to harvest. If plant starts tonget way worse then you will probably need to run a few gallons if eater thru the soil Good luck 👍
