I have brown spots on some leaves lower down on plant. Have looked it up on internet and think it calcium deficiency. But I use Cal Mag. Could it be something else? I have picture up on diary.

Hi @MissSolasolita! I see you're having purple stems, bronze/brown spots, I guess it's affecting only the lower leaves? If so, that's certainly a Phosphorous deficiency. Try to increase P intakes in her next meals. Hope this helps, keep us up-to-date and happy growing! 👊

Can anyone help sort out the issue I'm seeing on the lower leaves? I think I'm either between nutrient burn or potassium deficiency? I did up the nutrients a bit this week when I saw yellowing, but also have had high runoff pH the whole grow. Though haven't seen any other issues.

A number of lower fan leaves have started to yellow and die on both plants. I have increased FloraMicro dosage but it doesn't seem to have helped. Is this something other than an N deficiency? I think it is too early for the plant to be scavenging resources from the fan leaves.

How many times could/should I defoliate these Cobras? The Last photo shows a before & after which took place on May 31st and since that time, she has regrown to the point prior to defoliating. Should I repeat another defoliation? Far too many branches are shaded, again!

What is going on with the Special Kush? Check out her sugar leaves - and it's only on them, it's not in the buds and it's not on the fan leaves. Deficiency? The other plants don't have it. Some kind of fungus? I removed all leaves that had it, and it returned on the other leaves.

In picture 3 above the new growth on the main cola sites is curled up and contorted. pH is a tiny bit high, TDs run off is around the 400-600 mark over the week. Humidity has been intense for weeks in the high 70s to mid 80s, I'm only watering to feed once a week. Help!

This seemed to pop up in the past day or so. Little brown spots on my lower fan leaves. Nutes splashing on them? Cal mag deficiency? Pic is in week 4 of diary. Also new par450 light in. What distance should 2 par450s be in 4x4 tent? overkill? Too much? How many plants per 4x4?

Looking at plant 2 on day 18, it appears the leaves are starting to stand up, pray, sticking up, etc. What could be causing this? I'm using T5HO lights. Total of 210 watts. Is she getting too much light?

Largest plant's bucket got empty on accident; Filled a 15gallon reservoir of full strength nutes and pumped the solution into the bucket as always. Next day my largest plant is dying and the other two are fine, looks like lockout. Flushed for a day and then added nutes, nothing..

There are some really big upper leaves, which are blocking the light and airflow for some of the grow nodes? Is it safe to get rid of all of them? Should I leave them where they are?

Hey all I just uploaded 2 pics from today that show the problem I’ve had. This is the first time I’ve had any issues like this and it was an hour after watering with ferts. pH was 6.3. I think some damage is from spilling but that doesn’t explain the widespread wilty/weak leaves.

Have a look the leaf photo's in Week 12 and tell me what excess/deficiency you see. I think it is a Magnesium deficiency but I'm far from sure. The leaves effected are mainly middle of the plant fan leaves or lower fan leaves on the cola's.
