proxx87
started grow question 7mo ago
Any idea what these bright spots can mean? Plant is 2 1/2 weeks old and those spots show only on older growth.

Looks more like a pH issue. Was the coco washed and buffered? Many brands claim to already be....how well they did so is often debatable.

Please have a look at the coloring of this plant. I thought it was the lack of zinc, but FloraMicro provides a healthy dose. Yellow is on the newer growth and not in the older leaves is strange. I fear raising the ppms as a previous grow burned when it got > 500ppm.

Pale leaves and some clawing
Total noob. First grow. Clones shipped by mail. 5 days in and they seem to getting a little pale and some clawing on top leaves of one. Watering daily. Added some fertilizer and worm castings yesterday. Is there something I should be doing differently. Do they look okay?

Plant does not look good, can anyone help?
Had already asked yesterday what a deficiency this can be, but yesterday it does not say as dramatically as today at noon. Need help don't want it to break, maybe one of you can tell me what I can do and what it is natural. Continue to stay healthy and happy growth.

Hongo mildiu?
Hace unos días, las primeras hojas presentaron zonas con necrosis, y día a día avanzó. Será por el riego foliar con ? Por el viento directo del fan? O es un hongo mildiu? Un día la H.R llego al 80 90%, el crecimiento avanza pero muy lento, el sustrato parece tardar en secarse.

Possible deficiency/humidity/pH problem
I've been struggling with same problem from beginning of grow - leaves having these dry yellow/white spots. The first week I used too high pH which later I replaced by rainwater - new leaves were healthy, but last night I left tent at 70% RH. Somehow it returned - still rainwater

Nitrogen Deficiency or Nutrient Lockout?

New growth is light green? (1st grow)
New growth is light green – seems like Nitrogen deficiency or maybe light-burn? It's been getting slowly worse. Water ph is 6.7, Fox Farms nutes, AC Infinity 4x2 w/ 200w lights @ 18" on 80% power.

Is This Mildew On My Leaves?
So I mentioned these pale colors on my leaves in my last question. (Please see last photo in Week 3). I have made a mistake - after scraping the leaf with my hand, it is definitely something on the leaves! Does it look like mildew? I removed the extractor fan for 1 day.

Deficiency or leaves turning red/purple due to flowering?
Deficiency or natural change due to flowering? I fed her additional CalMag and PK so I slightly caused nutrient burn. That does not indicate a deficiency normally. Thank You for any advice!
