look like bigger plant is suffering from magnesium deficiency, and smaller plant is probably rootbound and suffering from nitrogen deficiency. https://loudclouds.co/wp-content/uploads/2016/07/marijuana-deficiency-chart-jorge-cervantes.jpg

Yellowing tips
Hi, I'm a newbie grower here. I have an autoflower that is nearly weeks old. I have started to notice some yellowing tips on the leaves. I have been feeding it some vitasol and pm13/14 as well as watering every two days. The growing medium is worm casing compost and perlite.

Heavy fast yellowing
I flushed my plant because of too high ppm reading from run off and now she seems to be going all yellow. Is this normal for this stage of the grow (all trichomes still white and small buds) or is this a definite nutrients deficiency during flowering?

Flush or what to do ?
Advice please. I watered yesterday but the stains on the leaves are getting worse. Now I don't know if it is deficiency of cal n mag due to nutritient lock out which might be due to ph being off as I have 5 reders and all of them show a different thing. 🤦♀️...or it is it rust?

Got some minor leaf burn this week. Only a couple leaves, I thought it might have been from being manhandled during the LST training, but not sure. What do it look like to you?

Discoloration on leaves. Why?
I was looking at a closeup view of an overhead pic I took yesterday and noticed some slight tan/bron color along the sides of the 2 bigger leaves. I'm wondering why. Nutrient burn? Sulphur deficiency? Something else? Any thoughts?

Saw a lot of yellowing in the flowers, not sure if its enough or too much nutrients, or not enough water or its a pest. I was suggested neem oil to get rid of the pest creating those white spots, any other suggestions about how to get her to look healthier and growing faster?

Nutrient problem??? Excess or deficiency?
What do you think is the leaf issue? Open to second opinions. Most everything stayed the same, except: > increased water: 2L to 3L per 7 gal of soil > introduced a bloom booster > increased volume of worm castings, molasses, mycrobes and ethylene to the tea
