hi guys! Have a little problem with only 1 of my plant in my homemade hydroponic system... i would think it is nute prob beacuse everything else seems to be ok. humidity around 50% and room temp about 28-29 on the day and 23-25 on night with lights off. Have them on 18/6.
here's a pic of the problem:
this is only happening to 1 plant of the 4 in the box... also i have 5 others that are small (little seen in the pic) and absolutely no prob there and also i have 1 larger plant that is looking very healthy and with no curling.. this plant is the only one starting to curl like this and started about 4-5 days ago... water has been changed 1 time since then but still continues to curl more and more but very slowly... any help would be greatly appreciated!
regards
