Strange bright spot on 1 leaf (at least so far) - please help - picture

when you say between 500 to 700 that is a huge range difference, just from my grows, i hardly ever run a strain beyond 750 ppms and that is late bloom on really large photos... From the pics it seems like your plant is in early bloom, i would be keeping them ppm's around 350 to 400 MAX, finishing up around 650 to 700 ppms in late bloom before chop


Thanks man, I'll keep up to your suggestion. But what should I do for now - flush her with clear water (3 x times pot size) after the soil is dry after last watering (at least it's my idea) and then start feeding again after the soil dry after the flush with very mild solution of bloom nutes (200-300 ppm) ? and what about molasses, is it good idea to add it, or leave it for late flower/skip completely ?
 
Yes, give it a good flush then let it dry out a bit, leave out the molasses, get back to basics for right now, Mix up a solution of your base nutes, and cal mag to around 350 ppm's, then watch what it does, if new growth is looking good your back on track. You might see some yellowing from flushing it out, which is fine don't freak out about that, you want to gage the plants health a few days after the new nute feeding.

One thing as a new grower, don't freak out about 1 spot on the plant, look at the over all health of everything. Don't go chasing problems to correct, what happens is you will most likely over correct and cause other problems. If the overall health of the plant is good, let it ride. Over time you will dial in your own growing style.
 
Just to add what you have there seems to be a necrotic spot due to over feeding.

Thank you very much for help ! Always learning the hard way. I have a question about Cal-Mag as I was searching in my country for something similiar and didn't find yet... only dolomite lime (but it's a powder and not a liquid and I believe it's not recommended to mix it to solution/ or sprinkle on soil and then water) - but I'll keep on searching, what would be the dosage of cal-mag per liter of water ?

By Cal-Mag you mean the Botanicare Cal-Mag ? (if yes it's not available in my country)
But instead maybe I can substitute this with Canna mgo 7% + Canna Ca 15% ?

1 spot was after a couple of days and I was not concerned very much by it, but after last feeding (32 day) there were a couple of issues showing up on whole plant namely: more brown/dry spots, curly/deformed leafs, yellowing leafs, leafs falling down, claw leafs - basically, the plant looked very healthy, but now when I look at her she looks very poorly, only flowers looks good
 
cal-mag from botanicare will work just fine. I typically water mine at about 3 to 5 ml to the gallon

ok, but if I cannot get botanicare cal-mag can I just mix 1,5ml canna mgo 7% + 1,5ml canna ca 15% to expect the same effect ?
 
Yea that will work just fine, another thing that will help you is to write down what you feed your plants, Write down how many ml's of each you gave and the total PPM's of the nutrient solution.
 
I have been trying to dial in Biobizz soil for a while. I had similar issues and many more, all pH related. I added a small amount of garden lime and after a few weeks things improved. pH meter really helped me out, worth having around.
 
Hi again guys, thanks for all help, I managed the issue, after the flush and 2 light feedings the things improved (no new dead leafs, new foliage looks healthy) - until now - I noticed that new small leafs on tops are curled up as on the photos, what could be the issue here ?
Last feeding was 2ml bloom 2ml topmax, 1ml gro,alg,heaven (all biobizz) + 0,5ml magne-cal, PH solution: 6.6 PH runoff: 6.5 PPM solution: 315, RH 40-50%, temp: 27C - 32C (unfortunately it's hot recently and it can be 30-32 outside during the day so it's hard to get a better temp inside, at least in the micro closet gro like this)
is this curling up - normal thing, or can it be an indication of some issue ?
