CalMag or something else?
aRecreationaliststarted grow question 4 years ago
Discolored leaves at the bottom of a 3 week young auto flower, full feeding schedule in diary.
Was thinking Cal-mag deficiency, but after 4 days of running 2mL/L Cal-mag supplements it's still getting worse.
Could it be lack of phosphor, and will BioBizz FishMix/Grow be enough?

I see a nice growing Plant, with wonderful green color. and she looks like ready to go into flower. I wont do big actions on her now. Because she looks well balanced. Your feeding schedule looks good, i see no bigger Problem here. Just watch out that biogrow contains 8 percent N and calmag 2 percent. that is adding up. One of the products is enough.
I would wait and watch.

Since you are growing under LED, I highly recommend adding 5ml/gal of Cal-Mag every single time you water/feed. LEDs really make the plant use up those nutrients. You also won't have potential deficiencies, either. Good luck with the grow!

@aRecreationalist Hi mate i believe it's an iron deficiency youll need to get something containing more iron than the biobizz I would use chelated iron as a foliar spray
for best and fastest results

Natural or Problem?Is this natural yellowing or is there a problem? pH to 6.3 and runoff is 5.7. The stem is awfully purple, watering/feeding is where I struggle. 1st pic - 4/21 and 2nd pic - today(4/24). Seems to have escalated over the last few days. Do-si-do auto about 10 weeks.

The clone has bad leaves. Need helpTell me, friends, what's wrong with my clone, I still can't figure out what's missing or too much. When I gave him just water PSH 6, ppm 10-15, he turned yellow. When I added water with a minimum amount of fertilizer for 1 week for vegetation, it also turned yellow.

Surplus or deficiency?Can't tell if there's a surplus of nutrients or a shortage of potassium? One plant looks like nitrogen burn and the other two look like theyre maybe a little k deficient. Was thinking of chilling out on the feed on the burnt one and just feeding micro to the other two. Thoughts?

Yellow leaf tipsHello,
I think I have a slight over-fertilisation.
Could someone have a look at this. And could someone explain to me in this context whether and how bad it is that the water does not flow through when watering. I have never had water under the pot.

Seedling Light-burn or ToxicityHi growers!
Is this Light Burn, or nutrient toxicity from nutrient dense soil?
2 Mars Hydro TS600 lights at 27" from seedling.
PH 6.3 misting soil - RH is 75-80%. - Temp is 77F
No light meter, so I estimate PPFD is in acceptable range despite using 2 lights in 2x2 tent.
