As already said by other users she seems to be overfed plus some light/heat stress. Dim or raise your light to prevent the tacoing and dial it back a little on the nutrients.

many problems with the leaves
the leaves have been turning yellow and falling faster and faster, especially those below; the upper ones curl and become burnt with dots and turn yellow should I try to put the lamp higher? (I haven't given fertilizers for a week)

Nute light burn
Okay I think I learned a lesson, 1/4 nutes next time (or nothing at all) seeing I'm seriously nute burning my plants, also one of the girls is about 20 cm from my light... Anything I can do to maybe calm down the situation? Flush? Never tried to and wasn't planning on doing it...

Nute burn in late flower
I've encountered some late stage nute burn and have brown and twisted tips on fan leaves as well as some bronzing. I am reading different treatment options for nute burn online but what else should I try at this late stage? I flushed ph'd water w/calmag and it's slowing a bit.

As you see one of my plant is stressed, another one has some other problem with leaves. They both grow in same place with same temperature and moisture but they have different problems. Temperature and moisture are normal, changes between 22-25° and %60-80

Calcium Deficiency ?
Got a little deficiency, can't find what it exactly is. Maybe a cause of this problem is that they got 3 days of nonstop light because I fucked up with the timer just before leaving house for 3 days

Surplus or deficiency?
Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

Discolored, burnt and curled up tips on higher leaves
Several symptoms, always on tips of higher leaves : they are discolored/burnt or burnt/curled up. LED @40cm (deemed 70% of 300W) and I just gave them the 2nd flowering feeding, 4 days after first one (pots were very light). I was planing to start compost tea... What should I do ?

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?
Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

Getting out of the ideas - VPD, nutrients or deficiency?
I'm getting out of the ideas as the foliar symptoms proceed. Lowered EC down to 1.8 from 2.2, pH in range. VPD is getting problematic as the plants seem to be respirating a lot during the day and it rises tent RH sometimes up to 70% - exhaust duct fan wont keep up. Temps 22-24C

I have burnt leaf tips and various other questions regarding the leaves. I would be very grateful for help. Picture 1-7 calmag deficiency? 8-10 various problems, what do you think about that? I'm interested in your opinion on the last 2 pictures. It's my first time, I have no comparison. 6th week of flowering.
