Vexatious yellowing I can't get to correct.
This Northern Lights auto is being vexatious...I can't get rid of the yellowing towards the bottom. Not overwatered, I've tried beefing up the nutrients, etc. with no effect. Any thoughts or do I just writing off as she's just being a jerk? Other plants in this grow are fine.

Browning leaves? Did a soil slurry and dropped the water from 6.8 to 6.2. Does that mean it’s locking out? How should I go about fixing this? In peat pearlite and worm castings. Added about 6 cups of lime to the 20 gallons of soil thought that should have helped the ph?

Hello all, I am having some issues with my outdoor grow. It seems the leaves are beginning to turn yellow. It has not received nutrients I’d say in about a month. The main reason for asking is because I do not want to over correct by adding nutrients if that may not be an issue.

Can I use magnesium sulfate foliarly?
Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect. I should add Dolomite Limestone to the soil this week.

Leaf tips yellowing. Overwatering? Or nute burn?
I recently flushed my soil with water that was PH 7 (my soil was a bit too acidic). My question is: are the yellow tips and browning due to the overwatering from the flush? As well as stripping the soil of its calcium? Thinking of giving them 3-4 days before watering with calmag

Yellowing Leaves
The leaves on one of my plants are really starting to yellow. To me, this looks similar to pictures of plants in late flower, rather than the examples of nutrient deficiencies. Have I read this correctly, or should I start worrying?

Leaf yellowing
Hi all. In the last 48 hours there has been a few lower leaves which have lightened in colour to a yellow. The whole leaf has changed at the same time so I’m not sure if this is an indication of an issue or if the leaves are being drained before the final ripening. Thanks 😊

Leaf Diagnosis Needed
I need help. Leaves are turning yellow at top of plant only. And only on American Pie. Not Northern Lights. I am using a Sonlipo SPC2500. Bloom mode. Is it possible to have lower ppfd levels and still get light burn? Thanks in advance.
