Please help brittle curling leaves

[BertWayne574]

Hi guys I have 2 plants growing currently, same everything from strain to nutes. One has weird leaves, curling down, brittle and weird color patches. Currently running fox farm trio and I'm 3 weeks into flower. Was told to add cal mag to my mix last feeding because I'm in coco. Any help would b great, thanks

IMO looks to much nitrogen ,because of the light i think you defo got calcium def ,and with the edges of your leaves looks asif to much heat ? could be just the deficiency,JMHO hope it helps

Alright thanks for ur help. Do u think I should just feed cal mag on my nxt feeding and skip fax farms or no?

How much are you feeding here ? are there days with just water ?

 

[wee_m]

hi now u have clear pic defo nitrogen to much and calcium need more as was said calmag ,or eston sault feed water feed . i use bio bizz nutes so bloom has N in it so don't need much of in flower

keep your feed going just cut back on the N get calmg .look up fox farm feed chart.....https://www.thegrowshow.org/fox-farm-feeding-schedule /all there

Alright thanks and yes I have been using fox feed chart. I feed twice a week and water between feeds with just ph water. So I'm wondering if the cal mag plus and fox farm together have to much nitrogen

 

[Redhemption]

It's nitrogen toxicity, maybe water it with water only for a couple of days and then go back to nutrients soft.

Appreciate it man I was kinda leaning toward that since fox and calmag both have a good amount of nitrogen

If you are growing in soil then there is no need to be feeding twice a week. Feed once a week, at half dose, and raise the dose if the plants look hungry. Unless you really know how to read plants you need to go really easy with nutrients. It’s so much easier to see when a plant needs more food, and just add more, rather than run into situations like this, and cause major irreversible damage to the plant. None of those leaves will recover from that.

Alright I'll cut back to once a week and see how they do thanks

totally agree better to under feed than over feed as can damage root mass plant growth ,and bud growth and your final yield

This reminds me of a previous grow. Ended up being my medium was hot (too much nutes) and ph too low... which would also lock out calcium.

Check ph runoff and lower nutes would be my suggestion.

This is a coco grow... he should be fertigating at least once a day till he gets run off.

Some containers do not drain well and can make your roots sad, which will make your leaves unhappy. If it is a hard container you can pull up the plant and view the roots. They should all be white and vigorous.
