started grow question 6y ago
Could this be the beginning of a Phosphorus deficiency? Or something else? Itâs not really found on my oldest branches, but more my newer ones.

answered grow question 6y ago
I would say that's a slight calcium defeciency, just add some cal mag to the feed.

Is my plant a mutant?
Plant A-- with the larger cotyledons has not shown any signs of true leaves. Is this a genetic problem and will it make it? Has anyone else had this issue and what were the results, if any. This is day 5 after coming out of the soil.

Cut more leaves ?
Do you think we should cut a few more leaves? You can see all the photos in my journal. I think there are 3 or 4 short weeks left before the harvest.

Still to early to tell? Noticed yesterday and have slightly worsened today. Not sure the issue but potentially magnesium? Getting close to top dress also.
Only on 1 of 3 plants so far. On older growth after getting dose of Recharge the other day. Maybe an N problem as I also use 484? Or mag? Using CalMag every other watering in RO at 150ppm as the soil has some cal and mag. Also getting close to top dress time maybe something else?

Possibly stunted plant?
So, my two smaller plants are a week behind, and my gimp plant I cannot fix. Have tried nutrients, flushing, checked pH, let it dry out, nothing is helping. Its been looking like this for 15 weeks now lol. Any suggestions?

There seems to be some paleness/yellowing on the upper growth. Upper leaf tips are slightly curling upwards and show some dark purple color. Last week runoff PPM was hovering around 1150-1250, so I'm dialing it down closer to 1000 ppm this week. Too much nutes or light intensity?

Damaged Leaf - Problem Identification
I know it's probably nothing to worry about since this is my by far best growing plant right now, but it doesn't really look like a mutation, more like damage or something. This is the only leaf i encountered, just wanted to check if anybody knopws what it is, hopefully no pest.

Was stimmt hier nicht?
Ein Freund von mir hat Probleme mit seiner Pflanze. Er fĂźhrt leider kein Tagebuch. Sieht fĂźr mich aus wie PH Lock aber der PH Wert vom Drain lag bei 5,95 ... das sollte doch im Rahmen sein, oder? GieĂwasser konnte ich leider nicht testen. Er hat mir nur den Drain mitgebracht.

Leaf started yellowing and growing a weird shape. Too much light? Too much water?
Issue evolving over the past few days (Sept 29th - Oct 2nd). The leaves are discolored, light, almost yellowish in color. They are also making a weird shape! Clear images of this in the post above. Tons of details about conditions/ environment. What's going on here? Help!!

Nutrient lock out hot soil question - stunting starts on 3rd set of leaves always?
I noticed that they always deteriorate when the third set of leaves are forming. If these are in fact stunted from the nutrient lock out due to hot soil, does it make sense that growth is vigorous until the 3rd set of leaves form?

Rust spots on lower leaves
rust spots on lower leaves on mainly one strain, started at tip of leaf. Happened after res change and had PH swings during that time until it was adjusted/settled. Full EC again. PH swing? Maybe cal(or)mag issue? PH is back at 5.9 now, running bennies. Maybe Slightly droopy? Thx
