Possible light stress?
Mrgreengrinchstarted grow question 3 years ago
Any help would be much appreciated, so the leaves are looking with a yellow tinge , my thoughts were light stress as had lights on 24/7 on to high and to close I have since then back off on the power of the lights and move them further away from the plants and changed to 20/4.

Hi there, I think you have Magnesium lock out due to imbalance pH.You mention that your pH is 6.1 and you are using dripping system.What is your run off pH and ppm.Let the water to be run off about 10~15% and check.Happy growing... ✌️

I agree with your light stress guess, I had a similar issue when I switched to LEDs and kept underestimating their power. Are the leaves brittle / crispy / crunchy? Brittle leaves that break when bent is also a sign of light stress.

Your ph needs to be in the range of 5.5 to 6.0 max for veg. 6.0 to 6.5 max for flower. Cheers

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.

Slight Leaf Discoloration. Early zinc deficiency?Girl showing slight discoloration on newer leaves. Mostly interveinal + little on the tips. Guessing it's an early zinc def. but would like another opinion. Watering sparingly at ph 6.3 - 6.5. No runoff yet, so ph may be higher in soil. Lower ph and watering til runoff next time?

Leaves Showing yellow edges and bandingIs yellowing of leaves and dark leaves toxicity? no curling . moved the lights further away. I'm growing organic. The plants look stunted short dense. I've only got a cheap pH meter calibrated. 🤞 use RO water pH- citric acid. Overall they are short dense growth wise

Yellow and skinny growth?Can anyone tell me whats going wrong here? I'm guessing the tips yellowing is nutrient burn from the MG soil. But the allover yellowing between the veins and skinny growth has me stumped. My first grow did something similar going into flower. I appreciate any tips or suggestions.Week 5

Seedling getting too much light?Is my 6cm tall seedling getting too much light? I downloaded a luxmeter app and for front/back cameras, it reads 4000-6000 lux. I'm worried about the light green veins. Is this normal? First grow so super unsure what everything is supposed to look like. Light is 18cm from plant.

Trying to narrow down cause of twisted/incomplete new growth with strange texture and discoloration of lower leaves.2 plants in 0.5L pots in BioBizz AllMix. Using tap water. Both have twisted/incomplete new growth with strange texture and discoloration on some lower leaves. Suspicion: 1. Very soft water-> CalMag deficiency. 2. Low humidity ~25-35%. 3 Need to pot up (planned to do it this week)
