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

[someonelse1981]

Hi All, It's been some time, no issues till now, I found some 'new' things that made me concerned about girl health, take a look:
1. another spot - just like the first one - already dry
2. curly leafs
3. some random very small spots on some leafs

some photos: (the white spot on 1 of the photos is the old spot)



I'm thinking that maybe I'm overfeeding. Watering only when the upper soil is pretty dry (every 3-4 days 1-1,2 liter of water + nutrients). I've added molasses last 2 feedings (7-10ml/1tsp) per liter.

Thanks for any suggestions.

did some more research on the issue and I'm pretty convinced that it's a nitrogen toxicity, my mistake, I gave her biobizz fish mix (high in nitrogen) among other nutrients, while it's already in flower and I should probably stop giving any high nitrogen nutes like this one only bloom, so what would you suggest doing now to try to help her recover.., since the last feeding was on 1 July I think that tomorrow or next day the soil will be pretty dry and ready for next watering (currently it's still looking wet so it may be + 2 days from now for this to dry), I'm thinking on maybe doing a flush with straight clean water, or a watering with bloom nutes only, what do you think ?


here's she

Things are getting worse every day. To be honest I think she won't survive, losing leaves, claw, curly yellowing leaves, brown/dry spots on leaves, only flowers and flower leaves looks well, everything else seems to be messed up especially fan leaves. I'm not really sure if I can help her to survive somehow anybody ? Any help appreciated. My idea is to wait until the soil is pretty dry so looking at the current moisture it will be in around next 2 days (still pretty moist) and then give her a good flush of clear water. I was giving her biobizz nutes according to the biobizz schedule (but half strength), however, last 2 feedings I added molasses which could be causing these problems ? It's my first attempt to grow and I don't have any idea what went wrong. Next time I think I won't feed much at all and for sure I won't add molasses (maybe I got wrong one ?). I really needed her for medical purposes, everything went fine from start, and now I'm pretty depressed...

There is so much missing info that its hard to say what is wrong.

What kind of lights are you using?
What type of soil?
Whats the PH of your water?
Whats the PPM's of your water?
Whats the temp of your grow room?
Whats the RH of your grow room?

Are you using Biobizz soil, Allmix/Lightmix?

Hey there I'm also a new grower but from what I have read which is alot is just flush your plant with ph water and your plant will recover the leafs that are effect will not but the rest of the plant will here is a link hope it helps you put some.

What kind of lights are you using?
CFL 125 Watt
What type of soil?
Biobizz Light MIX
Whats the PH of your water?
Not sure, don't have water PH meter yet (I need to get one) - but I have soil PH meter and soil shows 6 after last watering
Whats the PPM's of your water?
Water is collected from rain, and PPM meter (NaCL calibrated) shows 20-25 PPM but after adding nutes it was 500-700
Whats the temp of your grow room?
between 24-30 C
Whats the RH of your grow room?
between 35-50

The strain is Supersonic Cristal Strom auto, lights are 18/6 since start, 1 x 120mm exhaust computer fan, intake passive 100mm, 2 x 120mm fans inside one blowing on her, and other one just randomly mixing the air.

Edit: and I think I will need to get some PH up down, I wasn't that much concerned about PH becasue after some initial reading I was pretty sure that I won't need to track PH in the soil...(at least not at the level as with the nosoil/hydro)

Thanks for the suggestion and url ! I was looking at these 'diagnose it yourself' pages, but since there are a lot of possible issues, for beginner like me it's hard to choose the right diagnosis (some photos/descriptions of various issues look very similiar to the condition I encounter). The most possible ones I found is that possible that it's a Nitrogen Toxicity (because of the claw, curly leafs, brown spots) and indeed she definitely is in flower, and last time I added veg nutes high in nitrogen (because I was thinking that she's half in flower/half in veg - but probably it was not a good idea). Next thing that came to my mind is probably incorrect PH and the molasses I added after which the issue really got to the point that really make me concerned.

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
