This just started last night and is getting worse. Some details
-growing medium-b'cuzz coir coco
-House and Garden nutes per nute guide(a b, root stim
-2000w MH 14 " from canopy
-Drain to waste - hand watering
-R/O water at 5.3 ph
-week four of veg
-lighting schedule is 20/4
I was using 5.8 ph until last week after the soil meter in medium show high ph) I am still not sure if this is my problem.
I am thinking it is a ph issue since that is the only thing that has changed. I have a Hanna Combo Waterproof pH /EC/TDS/Temp Tester
that I test res with and a cheap soil meter that I test the coco medium with. The reason I lowered my ph was because the cheap soil meter showed high ph levels.
The other thing that changed is that I put a heater in with therm because temps were dropping to low 60's I am running 78 now. It could be because of the temp changes.
Anyone know what this is?
Should I flush the coco?
Is this from light burn?
Please let me know what you think.
Sorry for the first pic a little blurry, but good example of the problem.
My grow journal is also attached if you want to check out the grow details.
