Hi everyone-

Strain- Cheese
ph- 5.6
hydro- waterfarm
Light- 400mh
hours 24/7
watering- 2 times a day for 30mins
growing in- rockwool + clay peletts
location- 2.6 x 2.6 x 5.5 grow tent
nuts- Dutchmasters - part a&b gold - full strengh
temp-80-86F
water- bottled water.

So this is happening to my older leaves- not the oldest- but somewhere inbetween, the tip start burning and then the leaf starts getting lighter till it just burns off- it is growing new leaves on the top- but i'm just wondering what can be causing this.
Any idea on what this might be??
I have 3 plants int different water farms- and its happening to all of them.
:wall:

yeah i'd say nute burn (too high ppm in your nute solution). im strictly a soil grower so i cant say for sure in your case but i would try cutting your solution in half....ive never been able to use full strength without burning the plants...for that reason i quit going by what the label says to use a long time ago.
