Leaves getting light green to yellow
GRow_M8sanswered grow question 5 years ago
Hey m8 nice work 🙂❗
You ll need a cal/mag nut solution if you haven't already.
Use it with next watering and see how it goes.

hi @maxwell , due to the yellowing of between the veins of the leaves and the dry tips curling upwards, it seems to me a lack of magnesium. you have to apply some source of magnesium, calmag or epsom salt. if the problem persists, you will have to flush your substrate to clean the accumulation of mineral salts and apply calmag . good luck mate 👍

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?

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?

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?

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?

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?
