    Default Is this Mother plant going to revive ?

    Hi Guys/Gals,

    Here is a Mother plant which got over-fert back in April. I had to cut it back and leave it alone. Watering only with weak nutes every 5-7 days as it's under CFL's. Half RO and half tap water. Today I fed it 1/4 strength veg nutes at PH 6.2.

    Some of the new growth looks very deficient. What can I do to fix it?

    It's Super Skunk from Sensi seeds

    Quit watering it!!cut off dieing growth and back off the light!!!!she's sad but should survive and thrive again if given the proper condition's...no wet feet when you do water water twice what it need's to pull oxygen down to the root's use mycorrihazze for the root's health..she looks strong you did a good job with her so far! just mist her when it's hot never before bed..and you'll be golden my friend no question....wishing you the best!! jack my mother....too many top's too count twenty somthing! 2nd week flower.jpg

    have you pulled it out of the pot and checked the roots. I would do that just to make sure its not bound or you have any root rot going on. It def has some stuff going on. Nice green mid and lower foilage and yellowing brown foilage on the top. Just to make sure...are you foliar feeding? my best educated guess would be either a sulfur or boron deficiency or nute burn from foliar feeding. Both of them deficiencies indicate yellow or brown color of new growing shoots which is what I see going on with your mom. If the tops end up dying off best bet is to just top her and let the lower shoots grow out. She will recover. Maybe a bigger pot with fresh soil will cheer her up. Whenever I had a mom in a small pot like that that started to get "angry" I do a repot and she cheers right up! You might want to get that ph up to between 6.5-6.9. 6.2 is in the danger zone for soil grows.

    quit watering her? She is watering it every 5-7 days. that is plenty of time for the soil to dry out smh.

    Hmmm...really yellow new growth is usually another sign of over fert... As for the idea of it being a micro deficiency, only if the overfert caused the deficiency, in which case adding the missing element in greater amounts will not help...it takes a long time to "grow out" of overfert...A long long time sometimes...but also check to make sure that your plant's aren't root bound, usually a root bound plant will yellow like a deficient plant though---down low...

    The thing is, that pot is 11L and the seed germinated end of Feb. This is it's 3rd home since and got transplanted about 1 mth ago from a 7 L pot. Plus 11L is very big for me and I don't have a larger one. I wish I'd checked the roots before I watered it. It's really heavy now so I'll have to wait a few days to check.

    I'm not foliar feeding, it's only had weak Neem spray. DSC05515.jpg This is my Pineapple Chunk Mum. I want the Super Skunk to look like this !!

    what about the ph being 6.2 and possibly locking out P/Ca/Mg? That has to be a big issue also. Here's a chart for ph and nutrient uptake...

    I had thought about that but the initial PH of the Canna soil is PH 5.8 - 6.2 and the Canna Veg food stated to keep the PH in the range.

    I can raise the PH to 6.5 for Mg or add Mono nutes Mg

    The thing is..if you add Mg without fixing the ph first the Mg will not be accessible to the plant, thus causing it to build up in the soil and it will interact with calcium uptake. I always notice deficiencies start when my ph drops below 6.4 and gets worse as it gets closer to 6. What happens to my plants is the opposite of what is happening yours though. I get ph claw and leaves start to get rusty and orange spots all over the lower and mid level fan leaves and secondary leaves. Let some other more experienced growers chime in on this, especially ones more experience with the type of soil you are using then come to your conclusion You can always call your local hydro shop too and describe what is going on to them. They are usually very well informed and willing to help their customers.

    Yep..P starts to become inaccessible under 6.5
