3 possible reasons. 1. This plant wants more nitrogen or ph levels are slightly too high. 2. This plant is more sensitive to light and doesn't like it being so close. 3. This plant has red /purple genetics and a different "pigment" 🌱👍🌿

CalMag issue. If your giving them enough nitrogen (talking about BioGrow) then this is definitely a calmag deficiency. 😎

What is this leaf showing?
Anybody knows what is going on with this plant? My first guess was nitrogen toxicity because of the leaves clawing down a week ago, but I am not fully sure anymore with how the leaves are looking now.

Help me get her better.
Really need some advice on plant 3. She is now showing a lot of yellowing on bottom leaves. But now starting to move up to the top leaves. Can anyone help me get her better? Don’t like seeing her like this. I thought it was lockout at first but looks more like an N deficiency.

Deficiencies? Brown spots, yellowing and purple stems
What is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.

Brown leaves and red stems. Is this a calcium deficiency ?
I had an iron toxicity recently that may explain the brown parts but it may look like calcium deficiency. There are many red stems too but it maybe something else like the bad Ph and overfeeding from the previous month. What do you think ? Thanks !!
