Hello fine people! Just had a quick question about some leaves on my plants. Nearly all the stalks seem to have at least one on them. I looked up the nutrient deficiency chart and the closest i cam to was Calcium deficiency. Another user stated it could be rust fungus. Anybody care to shed some light?

Im growing under a 400hps in a waterfarm. Have a dual airpump which runs to the drip ring and an airstone in the res. For the last two and a half weeks ive been feeding her with liquid oxygen (h2o2). A week with just water and liquid oxygen and last week started back on the nutes. Started with 400-500ppm and today bumped up to 600ppm. Now it could be that i have root rot as well which led me to adding the liquid oxygen.

Any help would be much appreciated :D

Does not look like rust fungus. I lean more towards cal def. Not an expert, however, have had rust fungus before.

Well thing is im in ireland and cant get calmag here :( tough to even find it in the uk

BBbubblegum - Ya i know i should be in 1000's at this point. But id say about 2 weeks back i thought i had root rot so i flushed with water and liquid oxygen for a week. then just last week i started introducing nutes to her again. wanted to start low and make my way up( as i read what should be done if you have root rot)

But im wondering if i do in fact have root rot that the leaves are showing the symptoms of it?

You have a root disease coming on. Don't use that h202 again and get some beneficial bacteria and apply them directly to your roots after you wash out that H202. That 3% stuff is not good for plants or animals. You need the food grade or better H2O2 or you are just going to poison your plants.

Thanks for the reply Situation. I had been using Cannazym up until 3 weeks ago but when i suspected i had root rot i stopped with that and used Liquid oxygen. The H2o2 content is 17.5% and there isnt much left in the bottle. Maybe 30/40 mls. Which will be used up by this time next week. Some people told me to stop using cannazym and start with h2o2 and now your saying the opposite. I think after this bottle of h2o2 is finished im going to start with the cannazym again

What do your roots look like? May just be hungry. Outside of hydro nutes, the only alternatives to calmag I can think of are alfalfa tea and epsom salts... I have only used them in soil though. If you attempt it, watch the ph. I'll step back now as I have zero experience with root issues (knock wood). Good luck, I hope someone can help get your grow sorted!

If you can get pool shock treatment, basically bleach, but it is calcium hypochlorite. This will kill any organic compounds in the water so you can't run bennies only chemical ferties, but will lick that root rot.
The brand here in the states is (hth). There are so good threads on here about it and how to mix. The ratio was 2 grams of powder in one gallon(4 liters) mix that up and then use 2 oz(60ml) per 4 liters or 15ml of mix solution per liter of water.
