kevgrowstarted grow question 5y ago

Today I noticed on Plant #1 some of the stems closer to the light are turning red, is this a bad thing? Should I lower light intensity

also consider that in flowering plants produce less chlorophyll, and consequently the leaves of the leaves above all but also the main ones and even the buds become purple. however, it does not seem like a deficiency.

Looks like sunburn. It's not a reason for concern unless it develops other symptoms.

If they are green underneath then its from too much light, if they are all the way red then its lack of phosphorous.

Dark Green Leaves and Purple Stems Plant B has had no nutes its entire life in FFHF soil (3 weeks). Stems are a purplish color and starting to droop a little. Water is always pH'd around 6.3 but I haven't tested the runoff yet. Phosphorus deficiency? Heat Stress? Watering conflict? NL Photo just started flowering.

The stems began to turn red Guys, I need your help! The stems began to turn red. Yesterday it was less, but today it is more saturated and spreads to the veins of the leaves. Could it be a phosphorus deficiency, or am I worrying for nothing? And what is better to do in this case?
