started grow question 6y ago
Please have a look at these leafs! I gave a new dose nutrients by wormcasting rockdust and guano. Also some seashell chalk. I waited a bit, but it seems to continue spreading, at low pace.

It looks like potassium defficiency. If You are going the organic route, you can use a banana tea.

Could be nitrogen, but I would bet money that your runoff is too acidic so you have to flush just a little bit. Cheers!

Did you mix a shake or put directly into soil. There's alot of nitrogen in that mix. I'd flush and remove some of that build up.

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 !!

Found six different spots of small bud rot on amnesia and removed it all. Should I start flushing now and chop in the next few days? Or push it longer. Expecting rain all week so might be time to give up. Also, how much longer should she have gone?

leaf tips #2
Hi, continuing the previous question. pH runoff was 6.1 So I decided not to flush and gave it CalMag. Since then yellow tips doesn't spread any further, but the fan leaves on lower branches become fully yellow and died. Does that mean problem is getting bigger and I should flush?

Heavy fast yellowing
I flushed my plant because of too high ppm reading from run off and now she seems to be going all yellow. Is this normal for this stage of the grow (all trichomes still white and small buds) or is this a definite nutrients deficiency during flowering?

When to start using Cal Mag?
Tomorrow my Bruce Banner plants will be 2 weeks old. One plant is showing some yellow on the left side of one leaf. No yellow on any leaf tips and no claws. I believe I may have been under watering. My question is should I/can I start using Cal Mag or should I wait longer?

Did I give too much fertilizer??
So I decided to add in some soluble fertilizers. I gave it a 1/4 tsp (50% of recommended dosage) a couple days ago and noticed some yellowing of new growth on the bud sites. Is this a sign of excess potassium and phosphorus? I gave it Fox Farm Open Sesame (5-45-19).

Cut off yellow leaves.
Can I cut off these leaves? I am worried that this is an autoflowering plant and it will be an additional stress for it. But it also seems to me that it is spending some effort to keep these leaves alive and it would be better if it spent this effort on the buds.

Hi Growers! First grow here and I'm concerned about new yellow spots on my lower fan leaves (one tip is dark too). Soil is Atami Kilomix, heavily fertilized. 2 days ago only one leave was affected. What can it be? Mg def? N def? P def? N tox? Too less water (100ml every 2-3days)?
