Yellowish plants.
What can be the reason of yellowish plants? Too dense soil? Wrong water ph/ watering? Or nutes deficiency? What do you think guys?

Yellow leaves black tips
What’s happening with this plant? After watering all my plants 2 days ago, one of them has been quite droopy and developed these yellow areas with dark tips. Is it a watering issue / heat / deficiency? Thank you

Hi, I've noticed these spots on the leaves, does anyone know what they are please? Leaf Septoria? I hope not. It's a soil culture under leds, I used Biobizz products (Bio grow, bio bloom, top max) with biobizz calmag, I adjusted the ph to 6.5 with biobizz bio down. Thank you,

Newbie:Now in three weeks: the lower leaves start to turn yellow quite fast and it is moving to the leaves above it already. One disformed leave as well. Growth seems to slow down a bit. This is fresh fertilised potting soil and I am pretty sure I am not overwatering. Any ideas?

Yellowing to slight grey leaves
What's the cause of the older yellowing leaves with some grey and the slow spread to the newer growth? I'm between pH problems and or deficiency but not too sure.

Fan leaves yellowing
Hi there, today I noticed that some of the fan leaves had this weird yellow tattooing on it so I want to share it to hopefully understand what it indicates. Please refer to photo. The one in the photo is the most affected, there are a few others with the same but to a less degree

Need help diagnosing and remediating issue in flower Yellowing of leaves, splotchy “stains” on leaves, purple on new growth and stems
Been using 1/2 dose big bloom, grow big and cal mag stopped using grow big two weeks ago. Ph water between 5.7-6.5 each time and letting top inch soil completely dry between. Alternating water and feed. Should I wait for it to dry to try a flush? Additional nutes? I’m lost

Wondering if the amount/type of yellowing leaves is normal at this stage? Seems like maybe a nutrient defeciency (maybe burn? I dunno!) but given the stage of flowering not sure what should/can be done at this point. Have been providing ~1/2 dose bloom nutes (9-16-16). Thanks!

Spots and yellowing on the leaves
Good evening I have an autoflowering at the eighth week and recently yellowing has begun to appear on the leaves that I don't understand if it is the leaves that go towards the natural end or a problem of burning of fertilizer or even a fungal infection.
