BIYEIstarted grow question 2y ago

All the basic parameters adjusted adequately since the second week show this problem: temperature, EC, pH, humidity, VPD, lamp power, light cycle, and ventilation. I don't know why my plant is showing this. I used the General Hydroponics manual for LIGHT Feed.

Hello mate, looking your plants this porblem seems to be linked to immobile nutrient, like Mn Zn Fe. Normally all problems that come from immobile nutrients start showing in the top of the plants. Try to look some guide that teach how to recognize which of immobile element is boring you now. Good luck and happy journey!

Nitrogen toxicity is what it is, it is not a deficiency of any sort...............basically over fed/nutrient burning.

Probably a root problem what do your roots look like are you useing anything like hydrogaurd. Growing hydro is hard don't get down on yourself. If the plant dies die I suggest tring soil or coco or something similar next time

Yellow leaves The lower leaves turn yellow Is it due to a lack of nitrogen, or is it self-defoliation of the plant? (photos at week 5) I look forward to your advice) Should other leaves be defoliated or left as they are?

Yellowing leaves.Accidentally resolved my original question instead of liking a suggestion and I cant change it 😅 Same issue still applies for now. I have been testing the PH going in but not out so I will try this and pass on my results after the next water 👍 Open to all observations.

We've had some really warm weather the past few days. This morning, just before the lights switched off, i saw it was 31.1 degrees C in the grow tent. Are the yellowing leaves a concern? The yellowest leaves are really brittle. I don't believe they're under-waterd.

Over the last week, I have noticed quite a lot of yellowing of leaves, along with them drying out and getting brittle. Now that I am checking the PH of the nutrients, and adjusting to 6.0, I have no idea what's going on. Any insight as to what the issue may be, is appreciated.

Light burn?I noticed the tips of the top leaves are becoming paler, even slightly yellow. Could this be light stress/burn? My LEDs were approx. 30 cm from the canopy, now moved them up 15 cm.
