It's looking like you need the cal mag, looks like both deficiencies are beginning to show. If your using LED lights I'm beginning to think cal mag is a definite product people need. Most the time I see cal mag problems in questions and 99% of the growers are using LED lights.

Leaves color changing in flower!!!!what do you think ? deficiency? or is just normal for leaves to become like this after 7 weeks from seed of an autoflower? max i fed was 400pm just once. I don't think thats overfertilization. Maybe ph lockout? today i fed with 4.5 litres of compost tea + enzymes! pots are 14L.

Seem to have a deficiency I am unfamiliar with. As you can see in picture 5 the leaf is changing colour to a light green, in the part of the leaf that is light green is very crispy and crumbles when you touch it.

I need advice on what to do with this plant. I flushed her a bit and I think nutrient burining is not showing on new growth, what ppm should i feed her?I watered only last week and mesaured runoff ppm and ph. Water was 350 ppm and 6 ph and runooff was 700ppm and 6.7 ph. Before when i fed her with 850 ppm runoff was 1500 ppm. I would continue to water only but there was a lot of yellow and pale leaves so gave her light dosage.

yellowing fan leaves after dry period Some of my fan leaves are turning yellow. I haven't defoliated much so I think it's good that she's sucking all water and nutrients out of old fan leaves. Anyway, since it's my first grow I would like your opinions. Are they yellowing because lack of h2o? See pic of dry, wilting

She has yellowing and dying leaves issue for a while now. I was giving more nutes lately to combat the issue. Now burnt tips say it is to many nutes. So I decided yesterday that I should water with a bit of calmag before next feeding at beggining of the week.

Hey Pros, All girls are from the same mother and they get the same feedings. I think my light is a little strong. The plants directly under the lights are lighter green than the ones on the outside. 😎 What do you think? Thanks -NorCal311

I have some concerns about coloration of leaves. anyone care to chime in? Do I have an issue going on? I had light about 24" from buckets, I recently raised lights up to 36" as I was concerned this discoloration could be caused by light burn?

The further I move the lights out, they are now at twice the "ideal" placement of 14" at 28" and the yellowing on Maggie and Bra is disappearing to a great extent. Do yall know of any deficiency that makes a plant highly susceptible to light burn?

Can anyone identify what is happening with the lower shade leaves? A progressive, patchy paleness, from the spine of the leaf outwards and sides of leaves are cupping downwards. I gave cal/mag twice through the week along with bloom nutes. Is this a deficiency, small container..?

Any idea what's going on ? The plants kept growing (slower tho) but droopy leaves and yellowing/pale green. Some have spots, as you can see on pictures. Also some purple/reddish branches/ The constant (temperature/pH/airflow) are undercontrol. Thanks a lot !

In week 4 I planted the plants in a richly fertilized soil mixture. The leaves of the plants are now becoming more yellow. Do the plants suffer from a nutritional deficiency? What should I do? Adding organic fertilizer to the water tank could lead tot clogging of the tubes....
