Ph problem?
Aonjacktallbeckstarted grow question 4 years ago
Is this a ph problem or something else? My meter doesn’t seem to be accurate. I’ve been feeding top crop veg once a week and ph 6.3 (soil), my run off was a bit high, a gave just plain water (ph 7) but no help. Photos from two plants. Heeelp

yes, it looks like ph issues, how high was your run off? ph 7 is not good for the plants, usually it should be between 6-6.7 (for me it works best around 6.3-6.5). Try to flush it with water in this ph range. and dont forget: the damage on the plants won't go away, you see that the flush works when theres no more new damage on the leaves, plants dont "repair" the already damaged leaves.
happy growing <3

Underfeeding?Beginner grower here. Had some issues with underwatering and it's slowly recovering. Now am unsure if yellowing leaves are signs of underfeeding as it's still early in flower or due to the underwatering. Bottom leaves yellowing and dying off too.

Hydro. If the plant is overfed, can the ec possibly go down when they are given new nutes ?Usually they eat 0.1 ec when I add nute or with a new tank and ph goes up. Then it stabilizes and ph starts to go down till I refeed since I have a small tank. Right now there maybe a nute block but EC still goes down like they are hungry... Hydro with a small tank is confusing..

Need help identifying the deficiency hereI just started seeing some kind of deficiency on the lower leaves of my plant that's still pretty young. Can someone please help identify? Just tested the PH and it's at 6.4. I'm not seeing any spots on new leaves. Do I ride this out? Do a flush? Appreciate any advice!

Top leaves are yellowing in flowering-Is this Nutrient deficiency or excess or lock out?I am growing 3 Auto's.
One of the plants seems to be much more affected than the other one.
near harvest/Cloudy Trichomes no amber
I just gave them all a feed with the recommended Fox farm nutrients which is twice the concentration they normally get.
Any ideas?
