Sitejstarted grow question 3y ago
Good afternoon My first grow on coconut substrate. The edges of the leaves have turned yellow. I give Kalmag at each watering 0.5 ml/l, maybe it’s not enough? Fertilizers Grow 0.9 ml/l Micro 0.6 ml/l Bloom 0.3 ml/l. Ph - 6.0 - 6.2. I noticed problems on the 17th day.

I would lower my ph to 5.8, which is a suitable ph for all stages of growth in Coco Coir. Test run off ph as well. I would also double the dose of bloom your giving from .3 to .6.

It's great that you were able to find your problem. It's necessary to calibrate the pH meter if possible once a week.

Growing in Coco with no EC meter is like flying in the fog with no radar…
You must get an EC meter otherwise you won’t be able to feed correctly or to readjust EC levels when it’s needed.

Yellow tips on newer leaves. Nutrient burn or something else?I have noticed yellowing on the tips of newer leaves that seems to be slowly getting bigger. Nothing on older leaves. Start of Nutrient burn? I also have noticed some yellow/brown spotting on older leaves but that may be related to earlier PH flux that has since been fixed. TIA!

Harvesting a struggling plant or just letting it fightCan she be saved or just flush her and harvest what I can? She doesn't appear to be happy. Has some CBD genetics so the lack of trichomes don't worry me.
Rest of my garden is fading as well. Flushed em last feeding and they didn't seem to like it.
