Winged_Growerstarted grow question 5 years ago
I have about 3 weeks left of flower, haven’t started flushing and had some deficiency in the beginning. The yellowing is starting to creep up to the smaller, upper leaves. I’m thinking a cal mag issue since I have not supplemented with that at all. Is it too late to give ?

I wouldn't introduce more/new nutrients this late into flower, especially since your plants look pretty good overall. You could try and reduce your day temp, as 1 of the benefits of calcium is help the plant handle heat stress. Hope this helps. Good luck and happy growing! 💪

Dark green leaves, check; clawed leaves, check; burnt tips, check; interleaved burns or peeling, check. What you have is nute burn, mainly nitrogen excess. Just for reference, cal / mag issues are present several weeks before showing symptoms, if it were that, there would be no point to give it at this point. Stop feeding and give the plant water only. Next time use an EC/PPM meter, they are a great tool in preventing over feeding.

Yellow blemishes1 week old seedling is starting to develop yellow blemishes on initial leaves. Soil is biobizz lightmix, PH 6.2 from bottled water with no nutes, 150w led light is at 50% and 25-30cm distance. Is it a cal-mag deficiency, light burn, genetics, or just too soon to worry?

Slight lightburn?First pair leaves on left plant turn slightly lighter, first sign of yellowing a bit. Also I think they are a bit in a V/praying shape.
2 full weeks old under 75% of 200W leds about +-45cm. Should I dim them a bit more/hang higher?
Other suggestions maybe?

Is this Stating something or is it paranoyaI had a few leaves that were turning yellow, but they are lower leaves that are slightly yellowish on the outside, generally the plant has become a little lighter since it started flowering.
Am I worrying too much?

What may caused the issuesChecked the runoff and confirmed 6.2PH and 130 ppm on water.
checked on my Tank and same was happening.
so gave a 603 ppm solution of cal/mag. Grow A+B perfect pH connoisseur, H2O2 at 5.8 pH.
Will await for results.
i think at week 3 theyre supposed to eat at least 600 ppm?

Problem in 5 Week of VegetationNow in the 5 week of vegetation. The plants are Tropical Gelato cuttings. Everything was great until recently. They looked great.
After another light fertilization, the condition of the plants continued to deteriorate. Soil PH value is between 6 and 7. Can Someone help?

Starting to yellowSo I had good growth up until 2 days ago when the one plant started to yellow. I had them going 24 hours a day and I got grow dots mixed in the bottom two thirds of the pots. Could this be light stress? or could it be hungry?
