answered grow question 6y ago
What I would try first is to bring the ph down to 5.5 - 5.8. The 6.7 its at is out of range for dwc and proper uptake. Good luck

Hi, I'm new here. I wanted to know what the reason is for these yellow-brown leaves I have. I'm a newbie; it's my third grow. Could it be over-fertilization, a lack of some nutrient, or some bug? I'm sending pictures of the affected leaves and the plant in general.

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.

What is causing this Leaf discolouration overnight after a lot of tent work yesterday
Spent a lot of time in the tent yesterday. Everything was fine and this morning there’s bad discolouration on the leaves of some plants. I did lower the plant (was way too high) so may beight burn - but it’s only on some plants I did make two mixes of water/nutes

Hey, on my biggest plant, the leaves are starting to turn yellow from the outside and getting brown spots. Is that a sign of over-fertilization? All the other plants don't have this. Or is it too little?

Is this a disease caused by a lack of calcium and magnesium?
I pruned these problematic leaves during the flowering period, wondering whether this would lead to a decrease in yield. Calcium and magnesium were added every time I applied fertilizer. What caused the disease? Overnutrition burn?

I have no idea what these brown spots are on my seedling?
Brown/ rusty looking spots on seedling. Only thing I did was spray with a Epson salt and B52 foliar spray. The soil is deprived of magnesium so that’s why. I think I corrected by using cal mag. The sister plant is a few weeks ahead and showing recovery.

Brown spots on older fan leaves
Spotted some brown spots on 2 of the older fan leaves today. Any thoughts on what the issue may be? Does not rub off- was worried about rust at first. Some more info that could be helpful is that I am using RO water. Thinking about rasing the lights a little higher up too.
