So for last year or so I have been growing Sativa dominate plants due to they can handle higher temps and easier to maintain and I have had great yields with excellent reviews . But I have been wanting to try some indica dominate plants so I have this white rhino that has been in flower now about four five weeks and has this curling of the fan leaves going on I'm in dwc/areo combo I have been growing
This way with the same nutes for over a year and a half
With excellent results with many different stativa strains , is this just a indica thing ??

could also be high humidity in flower i had this my leafs went move like a v shape upwards and had small rust spots on the edges of them also curling up do u have adiquate airflow as indicas id think would require more as they are more bushy my problem got sorted when i repositioned fans and set them to come on a cpl of times during lights out i was finding beads of water on my leafs at lights on also invested in dehumidifier only usually need to use it round weeks 5 to finish here as humidity gets through the roof more so during lights out here in the uk

Ty My nutes haven't changed in a year and a half never seen this before I use pure blend pro bloom 2-3-5 at 100 MLs per 8 gallons of water , my ph in both tubs swing from 6.2- 5.8 in a few days then I bring it up but honestly that all clock work all my plants are feed the same it's just when I switched to this indica , the lights off humidity get to around 66% and lights on is around 32% thanx for all the replies I'm gonna try and increase air flow a little bit because it seem to be getting a little worse

I have had issue with to low of a ph . about 4.0 way to low and locked out nutrients . I am getting lazy not ph water when I run clean water instead of nutrients . water is 8.5 never had an issue yet . I wonder how high it can be run before a problem shows.

from what i read in mel franks book its more acidic soil that cause issue and cannabis doesnt have as much issue with alkaline its more the high acidic soils its less keen on a little acidic is ok but any more and ur asking for problems

indica lants needs much less N then sativa plants

so you didn't change your nuts feeding, but the plants you are growing need different feeding.

the extra N could also be the reson for the browning tips around the leaf - calcium deficiency.

Awesome
Ty everyone for your replies I will cut the bloom from 100 mls per 8 gallons down to
My old recipe witch is 70 mls per 8 gallons I will run low ppm for a week with a steady ph swing of 6-5.6 , this is why when growing a new Strain I never mix strains in same run until i see how plant reacts .

As Jim Carey said in "lier lier"
"Here comes the claw!!"

unfortunately, I've no experience with DWC at all so I'm no help.

Personally I'd of assumed over watering - ruling that out due to DWC my next guess would be the PH, the humidity or temp & ive seen similar with N issues also.

Wish you all the best with the strain switch though. :peace:
