    Default Big Problems - need help from Experienced people! Please!

    Strain : Vienna White Light
    Plant Size : ca. 1m
    Pot Size (l) : 11l
    Growing Space (m²) : 1m²
    Soil: Dutch Pro All mix
    Flowering Days : 26 Tage
    Fertilizer: Ive used Hesi Bloom 10ml/L on the 19th and yday i gave an extra Phosphorous Plus from Hesi, full Dosage

    PH : 6.5 PH (checked runoff on 19th and it was 6.5)
    Humidty) : 40-50% (70 at night)
    Temp: around 25°C
    Watering : around 3 litre every 5th day. (they are quite wet right now,since i added another 1l with P)

    So here we are... the upper/older leaves all start to claw,get brown spots,dry out and also turn yellowish,as you will see on the pictures. The younger leaves are all great as you will see too. One plant hast nothing at all the others all show the same symptoms. All plants have gotten the same amount of Water/Nutrients. On last Friday ive seen that one plant had the issue first... brown spots/yellowing from tip of leave and then curling up and drying out.

    So I thought its Phosphouros deficiency, gave em 1l of full Phosphorous Plus yday, and I thought it helped, but still goes on. So now I think,that maybe the 4 other plants,jsut cant take up the Nutrients? Maybe they are locked out? FLUSH? I dont know what to do... I cant really do anything,since the soil right now is super saturated. So will have to wait several days until it dried out imo. Also have white shit on (salt i guess) on drainage holes and white shit on soil (looked kinda moldy tho but funnily i saw THAT on the perfect healthy plant?!)

    SO PLEASE... if anyone knows what this is,or has a great strategy on how to find out/SOLVE the problem! Youd make me extremely happy!

    Take care and thanks so much!

    pH-Wert (CaCI2) 5,3 – 6,0

    EC 1.3

    ^^ those are the values that the earth had inherently. so maybe since i downregulated my ph to 6.5-6.2 its now to low? but i checked out some water that run through.. and it was 6.5... will have to check after next feeding.. which considering the saturation of the soil will still be at least 4 days.

    My guess would be lockout from overfeeding and possible salt buildup. Personally, I would flush. Are you able to measure EC? Would be helpful to know a plain water runoff EC.

    I dont have any ways to measure EC... problem is,that my plants soil is already really saturated.. im scared of drowning my roots and causing even more harm,than the lockout! But i definetly agree,that its probably a lockout,especially after giving them yday each a liter of Phosphor + maximum Dosage. But given that the leaves that arent affected are really green... it might too many nutrients. THE THING IS.. i have not given them anything but root stimulator up until week two and 4 days ago i startedwith 1/3 of the bloom fertilizer,once i saw the problems arising... so im not sure about overfeeding.. thing is also, one plant is really healthy and has no deficiencies or whatsoever.. so must be lockout? how can that happen tho... i PHed my water to 6.2-6.5? But yeah.. wait until all dry and then flush? flush right away? as i said... the soil has been wet now since 19th.. i dont wanna kill them,by flushing now..

    I also watered with quite the runoff the last few times... isnt it weird that salt accumulated then?

    Also, how dangerous is overall? Do you think this can kill the whole grow?

    So i can think of something,why three plants show more severe problems. They stood much longer in alot of runoff! So it might really be salt which means I just have to flush?! If so... PHed water right? 6.5? 3 times the pot size? As i said.. they are REALLY wetstill... so Id really like to wait until plants need water...?!

    I say that, because I have been growing in Soil for going on 12 years now, and never ph anything, and have pull 6+oz from my plants using as little as 222W LED and 250W HPS, with no problem at all. I will put A few of my plants to show you how well they do. Must be something else wrong, but I don't believe it has anything to do with PH the water.
