Bigdaddybluestarted grow question a year ago

What do you think is wrong with my plant? In promix moisture soil. Fed nutes twice. 2mL of micro, grow, and bloom. Last feeding I added 5mL of calmag. Soil is 100% inert at least from my research. Watering once soil is dry (every 5-7 days) One leaf is crispy. Tips curling down.

When your leafs “claw” at the tips, it’s typically an overdose of Nitrogen. Try cutting your solution back by roughly 50% on your next two feedings or even just skip a feeding and do 50% solution on your second. Another sign of over nitrogen is an abnormally dark green color of your plant.

Nitrogen over dose. In soil, I personally use a schedule of plain water/plain water/feed/plain water/plain water/feed....... and have done so for over 30 years now and don't get problems with over fertilization ever.

Problem?Hi guys, last few days I am noticing, that leaves are hung down a little.But not all the time. Light distance is around 100cm - as manufacturer recomends..I am watering plants every 72 hours, 1 liter per plant - since I have 18L pots, it cannot be too much. Any ideas? Thank you!

Over Fed, Watered or Lights to close?Either I over watered, over fed, or the lights were too close. I already raised the lights to be 24" again, the plant grew fast and was only 16" away. Should I wait to feed again or continue as normal? The temp is 73-75 lights on, lights off it was getting down to 63.

Curling Tips Why do I see those curling tips? I identified them as Nitrogen toxicity coupled with Nute burn, but flushing didn't fix the problem since Veg and I still can see them appearing in new grows. I want to add extra 0-5-4 nutes to help the overall growth of buds, shall I do it?

Leaves are firm but dropping flat, pointing downwards. Over watering? Diagnose and recovery advise?Would appreciate some input into the possible over watering issue?

Nitrogen Toxicity or anxious first grow?Hi all, what are the opinions on my first grow? Little stunted and I think the "claw" is from the FFHF soil post transplant. Pot is a little big (7gal) for this stage, but I was worried about multiple transplants on my first effort. Is this nitrogen toxicity? No added nutrients.
