greenteam Posted January 1, 2019 Share Posted January 1, 2019 Hi Guys, I have 6 Plants outside they were doing really well, but the leaves have started browning at the tips and getting crispy. the growth of the plants has slowed down alot. I am growing in coco coir mixed with some perlite. I am using bio buzz nutrients and mix 5ml with 5 litres of water. I have attached a picture What do you think is causing this? Is it possible to save my plants? Thanks in advance for the advice :) Quote Link to comment Share on other sites More sharing options...
Smelly Joe Posted January 1, 2019 Share Posted January 1, 2019 (edited) What happened before this started??? Did you feed them all the same cause I'm seeing same issues with all of them. A nice flush and start feed at 1/4 strength is a good beginning to get rid of any build up in the soil. I know with Bio Bloom they say to feed with every watering but I still give it every 2nd feed and alternate with my aact brews. I am also doing a grow in clean coir and is currently using seagro and aact but will be using Bio Bloom once flowering starts. Ps: is that the spot they stand permanently???

Trailblazer420 Posted January 1, 2019 Share Posted January 1, 2019 Are you in Jozi by any chance? Heat has been doing that to my outdoor plants as well Sent from my EVA-L09 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
killerx Posted January 1, 2019 Share Posted January 1, 2019 pics a bit fuzzy, but looking at the leaves, it appears to be affecting the lower leaves more, i would say it could be a nute issue rather than heat, heat would affect all the leaves or the top leaves more I would flush, and start feeding every 2nd day, my 1 sativa is very sensitive to the nutes had to dial the feeding way down 1 Quote Link to comment Share on other sites More sharing options...
greenteam Posted January 2, 2019 Author Share Posted January 2, 2019 @Smelly Joe @killerx @Trailblazer420 Thanks for responding guys. I have flushed the plants and making sure the PH is around 5.5 - 6. I am based in cape town. Do you guys think the problem is Nute burn or could it possible be a bit of overwatering? Here are some more pics Thanks for the help!! Quote Link to comment Share on other sites More sharing options...
Smelly Joe Posted January 2, 2019 Share Posted January 2, 2019 I would say it's nute burn with with a slight N deficiency. Go to hydro store and get some of this stuff and flush the ladies.... I understand why @Trailblazer420 asked about the heat. I would move the plants if possible because: White Wall + Stones + Summer Sun = Very hot and crappy conditions for the lady It might be that the sun damaged some of the leaves as well.

killerx Posted January 2, 2019 Share Posted January 2, 2019 (edited) its quite difficult to say for sure, looks like the leaves are curling on to themselves slightly which could indicate a bit of over watering with the coco coir/perlite, I wait until the top layer if dryish, if I press it between my fingers very little moisture should be left overwatering can also cause nutrition issues, as the roots wont absorb the nutrients effectively also when you are feeding, are you getting sufficient run off?

greenteam Posted January 17, 2019 Author Share Posted January 17, 2019 @killerx @Smelly Joe Hi guys, Just an update, I bought cal mag and mix about half a teaspoon with 5 litres of water at a time. Its been about 9 days since I started watering them with cal mag. I am not sure they are getting better. Do you guys think they will make it? Should I start feeding with Nutes? I have attached some more pics. I am wondering weather just to grow in soil as I am going to have an indoor grow. What do you think? Thanks for the Help Quote Link to comment Share on other sites More sharing options...
Green Leaf Organics Posted January 17, 2019 Share Posted January 17, 2019 (edited) That is not nute burn... that plant is starving. It's in an inert medium being given extreamly low dosages of nutes... that's what happens to a starving plant . Biobizz recommends 2-5ml per L , you giving it 1ml per L in an inert medium . Give you poor girl some food , start at 3ml per L. Edited January 17, 2019 by Green Leaf Organics 2 Quote Link to comment Share on other sites More sharing options...

I know they have a range specifically for coco, the normal range is for soil. 1 Quote Link to comment Share on other sites More sharing options...
Green Leaf Organics Posted January 18, 2019 Share Posted January 18, 2019 They only have one range and it's for coco or soil. You may be thinking of greenhouse feeding 1 Quote Link to comment Share on other sites More sharing options...
