I have a girl that is showing some brown spots and yellowing, mostly the lower leaves in the middle. What could be causing that? And what should I do now? More pictures and a video in diary

The problem again lies in your pH.... it's far too low for the essential nutrients to be absorbed by your plant. 6.2 is absolutely ideal but if you can get it between 6.0 and 6.5 you'll be fine.... I see you're giving her calmag - plant can't get at what you're giving her... get the pH up! Good luck!

You actually have a magnesium deficiency. Often with this deficiency, magnesium is present, but the roots cannot absorb the magnesium properly due to an improper ph. Therefore it is very important to maintain the correct ph and make sure your ph does not get too low/acidic in order to avoid a magnesium deficiency. I would try bringing my ph up to between 6.0-6.5 that way the magnesium can be absorbed by the plant.

Leaves doing weird stuff My leaves on one plant are doing this weird thing where some parts are yellow'ish. It looks like a mutation. She is getting the same nutes as the other 3 plants in the garden and they aren't doing this. I've never seen this before so I'm not sure what I'm looking at?

Nutrient burn?Hello I have one plant with yellowing leaves that are also curling downward. Only one plant of 6 has this problem, I suspect maybe this one is just sensitive to the nutrient rich soil? I am using fox farm happy frog and have added no other fertilizer. What to do, flush all?

Yellow leaves at the bottom Some few leaves, two older and two new ones, turned a little yellow. All of them on the bottom of the plant. I don't know if this is a normal development or perhaps Na deficiency? It's my first grow, so I don't have experience. Help would be appreciated.

General health Advice please just on wether it's looking healthy. :) I've been too careful with watering and some leaves turned yellow. Feeding 1 litre every other day but maybe that's too little? Stopped with the Biobiz fish and switch to growbloom. Leaves at the top look droopy still?
