Nitrogen deficiency, light burn? Calcium?? Which deficiency?
Growing organically with happy frog mixed with a super soil concentrate. I water them with spring bottle water, ph at 7.7. Recharge every 10 days. Top dress 2-2-2 dry amendments. No clue what’s going on with this, thought it needed nitrogen. Top dress. Some new growth looks good

Is this a K deficiency? Otherwise good at 47 days?
First grow is looking good. Started supplementing P and K a week ago - noticed signs of K deficiency today. Lower leaves yellowing, red leaf-stems. Should I just keep stay the course and keep the nuts coming?

Hey, anyone got any idea or clue what's going on?
I thought it was a manganese or iron deficiency from an early watering with high pH. Though I've fed/watered my other 2 plants pretty much the same stuff but she seems to be reacting really poorly. She seems to be getting better slowly.. I think.

Nutritions
I had started giving my plants nutes, but then started seeing minor nute burns, so I left them to dry out abit and gave there last feed just water. Now my question is now they are flowering shall I give them any nutes yet? Or just water for the moment till they use up the soil?

Can anyone help identify this tox/deficiency?
Week 6 I noticed that all the new growth has burnt tips I assumed this was a bit of a nitrogen toxicity problem since the leaves were all a nice dark green, no pale leaves were popping up. Also held back on feeds for a few weeks. Other forums said it’s normal but want to be sure.

What am I doing wrong?
I’m a new grower my leaves started to shrivel up at the tips and get brown. My friend told my it’s cause over watering so I water less but the problem keeps getting worse. It’s a month old and I use 2ml calmag 2.5 of micro and grow and 1 ml micro. I only water three times a week.

Purple stems-curling tips leaves point down
Guys the sides stems seem really purple!even the central stem.. Why? magnesium deficiency?or genetics? And that leaves tip pointed down; they are a problem.. Maybe N deficiency?(due the early preflowering for the wrong light cycle) Thanks :)

Please tell me why the veins of the leaves are so yellow!? what could it be? zinc block or cal-mag shortage ? pH all the time was 6.3-6.5, EC first was 0.7 today when I saw the yellowness on the leaves I lowered the EC to 0.5

Ongoing pH issues
Watered at 6.5 pH and runoff was at 5.5. I am going to start watering at a higher pH today and continue measuring runoff. Should I stop feeding at this time? I have been feeding 1/2 dosage of Fox farms trio with every watering last 2 weeks. Is there likely soil build up to flush?

Spots on yellowing leaves
Brown spots on dying yellow leaves. This has happened on most of my plants after budding so thinking it may be a soil problem. My guess is boron, manganese or phosphorus as the stems on some plants are red. It starts low and eventually ends affecting buds too so I chop.

Yellow leaves
my little GG2 is starting to lose many leaves (they turn yellow and fall even before drying) while the other is not having any problems (the only difference between the two is the "aggressiveness" used in the LST) it could be due to the flushing done (but less than 5 days ago) 🤔
