Can anyone help identify deficiencies in fan leaves?

Legal_STLstarted grow question 4 years ago

See the last 2 pictures of week 3 for reference. pH oscillating from 5.6-6.3 (currently at 6.3). Temps day/night @ 79/69. Following GH Flora Trio recommended ratios (but diluted down to 630 ppm). Raised to 800ppm today. Have not changed nutrient solution to date.

hey there, sorry to disagree with larimar, but this is clearly not light burn. Light burn doesnt yellow the leafs it bleaches them, the leafs dont yellow starting from the base and between the veins of the leafs . this is a magnesium related symptom. Just add more cal mag. Simple fix the problem will stop spreading pretty quick and the plant will recover. Hope this helps ! 🚀

To me it looks like atypical Lightburn ( you upped intesity=?) the burns will remain,,, but if you lower the lightintensity,,, plants will grow nice leaves again. Young plants like this get totally clear with 50-75 watt of Light those Quantumboards have an extreme high DLI output

Spotted crisp leaves What's up with these leaves? They've all been spotting up, crisp edges and tips curl. I keep flushing them and it helps. I feed them 1 tsp calmag to each gallon and often the mixture gets diluted as much as half. PH water was 6.2 but soil 4.5. 15" from 70% light.

Calcium issues?Is this the start of a calcium deficiency? Aside from these couple of spots the plant looks healthy, but I really don't want this to progress. I can't measure my PH for a couple of days, sadly, until I get the equip through the post to do so.

Brown leaves - what am I doing wrong, folks?They look yellow in the photo, under 250W of blue light, but they are brown. This starts at the tips of the large lower leaves and spreads quickly to the whole leaf. Also modest edge curl. What am I doing wrong here, folks?

Wilting leaves and copper spots? Save Me!These copper spots started appearing around 2021-01-28, and the wilting leaves started 2021-01-29. The newest additions to the environment were the much stronger MarsHydro 300w light. I've had to water more often because it dries out pretty quick with the rampant heat. what next?

Brown spots and patches I got some spots that look like cal-mag deficiency on 3/8 of my plants. I put some pics up that say "cal mag issue?" for reference. Not sure what this is especially when the others are looking happy. Let me know your thoughts <3

Leaves have some spots My auto flower has started presenting some spots, it's on week 3. But I've seen these marks since the beginning of week 2, been measuring my ph and everything looks fine. Maybe the super soil is a bit too strong, and it has to get used to it? The lamp is 27 inches away.
