Plant is 4 weeks old and starts showing yellow leaves in the under areas. No extra nutrients added because I use plagron royal mix soil wich has al the NKP for 6 weeks they say. Little bit of Root power and only water was given.

light bleaching
Why are my leaf tips getting bleached still? I have the light 18 inches from the canopy which is what is recommended for veg, and that's only around 400umol/m2s but the leaf tips keep burning. Temps are low if anything, consistently between 65 and 75 farenheight.

45 days flowering yellowing
45 days of flowering, is it a bad yellowing or it's normal for this phase? Always did 1ml/L of biogrow, I think I'll put 2ml/L till flush. It's nitrogen, right?

You are a SATIVA North Shore Maui! You grow tall like the sky! Strong like mountain! You are not descended from short plant!
Currently overthinking this plant's development. Pep talk not working. It is a sativa but the shortest plant in my garden. Maybe just needs a trim? The yellow is a concern too. I haven't dealt with a plant this bushy before so not sure if it needs help or not.

Should I do full flush til runoff is 300ppm?
So, it is obviously a deficiency, which probably caused by a lockout. Will the full flush solve it? Yesterday I fed her a full dose of flowering nutes. Including K. It didn't change much. Lower fan leaves continue to go yellow. Today 3L water, pH:6.2, runoff:0.6l, ppm:1450, Ph6.0

(Mimosa auto in coco) Yellowing tips on new growth
The top of the plant (new growth) is showing some unhealthy signs. The tips of the leaves are yellow and there are lighter green stripes on the leaves themselves. I googled and the signs match to a number of deficiencies, but i lack the experience to diagnose correctly. Plz help

Yellowing leaves on bottom of plant, end of stretch to start of flower. Am i seeing a deficiency?
Hi GD, Im in week five and i started to notice some bottom leaves on my girls slowly turning yellow. Could this be due to them barely recieving any light? or starting defeciency? I am on the feed schedule in the pic, and watering with a ph of 6-6.3 (every 1-3 days, when dry)

Ph ? Nut ? Not sure what it is on the excess/defiency chart. Details below
What kind of issue here? I think about the pH. -Soil : Light-Mix Biobizz (pH 5,5- 6,5) -Water pH : approximately 5.5 / 6 (initialy 7.4 and I read that is too high, I reduce him to 5.5/6) -Watering : 50ml every 2 or 3 days -Temp and humidity : 23 celsius degree and 44% -Pot : 11L
