Plants were green and healthy until week 4 of flower now at the end of week 6 and they’re looking pretty rough, the buds look okay it’s mainly the sugar leaves and the fan leaves are all dying necrotic dead spots started off as brown spots but it’s not a fungus. At first I thought it was calcium magnesium deficiency then botrytis but after much research I’m landing on manganese deficiency. I’m growing in Fox Farm Happy Frog through veg and I transplanted them to Fox Farm ocean Forest in flower. I fed them once in veg 3 part General Hydroponics and again I fed them once in flower beginning of week 6 General Hydroponics 3 part. I feed 2 mL of Cal Mag and 4 mL of Botanicare sweet every watering using r/0 water ph to 5.8-6.5All parameters are dialed in I’m sitting around 45% humidity at about 72 degrees Fahrenheit with a fluctuation of about 5 degrees at night. My question is this is my first grow and I don’t know whether to harvest them early because of the problems I’m having with the leaves or let them finish. The Strain is super skunk from ilgm
Thanks for the response and I am inclined to keep going just like you said until they’re ready to harvest. And I forgot to mention that the brown spots are what appeared on the leaves first at end of week 3 into week 4 then the leaves started dying with necrotic dead spots and what looks like tip burn. ABG(always be growing)
That’s one thing to keep in mind, old growth is old problems
If you have corrected issue, a big if I know, then the new growth tells the tale
If new growth looks good, then you are on track
This is a general statement but a good baseline to go with
Answer these simple questions the best you can.

-Distance of liquid below net pot (DWC)
-Temperature of reservoir
-TDS of nutrient solution
-Amount of air to solution

I’m leaning toward Cal/Mag (Magnesium specifically but my eye is not that great for diagnosing leaf issues)
Anyway more than anything correct your PH. Add all your nutrients to the RO water, then PH. You might try PH up’ing to around 6.6-6.8. I suspect what you’re facing is a lockout of the magnesium (and/or others) because you’re giving her a PH range closer to what you’d want in hydro, rather than soil. It’s just a suspicion.
Also I’d water to runoff and then introduce the PH & nutriented water.
Please fill out the Support Ticket and be as complete as possible. There is a reason for all of requested info. Can’t really diagnose without more data.
The next three waterings which are about 3 and a half days apart I’ll be giving them only RO water with 2 ml of Cal Mag and I’ll do like you said pH in the water at 6.7. I’m so late in flowering I’m determined to see this through. I’m on day 40 of a 56 day strain super skunk ilgm. Trichomes are still clear right now
Looks like a deficiency of everything, plants are hungry. A couple good feeds with proper ph and lots of runoff (mini-flush) could go a long way to keep the yellow death away a little longer.
