If I had to guess a bit of nitrogen excess, perhaps slight calmag deficiency.

Neuts lockout possibly??
Gave them all haircuts then topped off w new soil in the pots on Sunday night. Watered w nutrients but then today they looked like this!! They’ve gotten progressively worse since Monday morning so I’m thinking possibly a nutrient lockout? I watered just now w flora-Kleen

Nutrient deficiency help
~2 weeks ago I thought I had a calcium deficiency, so top dressed with Dolomite Lime. Is the current discoloration from the old deficiency or is there something else wrong? Plant 2 also seems lighter than it should be. Is it low on N?

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?

Help. White widow Auto day 7
I am curious about this white widow auto seedling. This is day 7. Seems to be losing a little color, but is still growing faster than the other 2 seedlings I dropped. Any suggestions on this? I have only been watering with distilled water. I have not fed any nutrients yet

Grey leaf tips
Booth plants are showing some kinds of burn and I am not sure if it is nutrient burn or light burn or if there is something missing. Looks a bit like MG deficite but shouldn't the plant take that from the soil in that state and age?

Possible overfeeding nutes?
Could someone possibly identify the issue on that one leaf? I had another like that a bit worse that where the edges started to curl. They were fan leaves so I ended up removing them as they were a bit worse off. Doing much better now, only guess is too much nutes.

Yellowing leave tips and clawing down, do I need to start giving more nutrients?
Hello all, I'm experiencing some yellowing leave tips on newer growth, it is paired with some light clawing (downside) on the newest leaves (only on the green gelato). I have used very little nutrients so far and have fertigated only once in fear of giving too much.
