Hi all, I am growing for the first time as it just became legal in my state, I'm growing 3 feminized autoflowers 2 lemon ak and 1 ak from 2fast4buds. Theyre in a marshydro 2.3 x 2.3 tent with the marshydro ts1000 light about 20 inches above the canopy. Ive got them in vermifire soil in 3 gallon fabric pots, I've been water 2 to 3 times a week with well water ph'd to 6.5. They're currently at 20 days of growth and a few days ago I notice some leaf tips starting to yellow and curl a bit. I noticed some dark green tips on some leaves which lead me to believe it might ne nitrogen toxicity, so I Watered with real growers recharge since I read the extra microbes will use excess nitrogen. It's been a few days since then and some of the leaves have gotten worse. But the plants seem to be growing just fine otherwise, any ideas what's going on? Thanks 20210807_173731.jpg20210807_173715.jpg20210807_173723.jpg20210807_173751.jpg 20210807_173706.jpg20210807_173852.jpg
 
I forgot to mention I haven't fed any nutrients as I read that vermifire is a supersoil and I shouldn't need to feed at all or at least not until I'm in flower. It may even be that the vermifire is too hot for these plants as I planted them in it as seedlings.

I was starting to lean towards overwatering as the problem, thanks for helping to confirm. I've been waiting till the first inch of soil is dry before watering but I guess that wasn't right.

I would suggest picking up the container to see how heavy it is. This will tell you how much water you have in the pot way better than sticking your finger in the soil. You will be surprised on how light it can get while still having leaves at full attention. A fully drenched pot can last from 3-5 days depending on temps.
 
No problems. Looks as healthy as it can be in prepackaged soil.
Leave tips clawing is just an indicator of high available nitrogen in the soil.
Yours is very minimal and the new growth already looks 'fixed'.
Nothing to worry about.

I have been trying to implement this technique into my watering schedule. I was under the impression that you're not supposed to let super soil get as dry between watering as I can't hurt your microbe count, so I didn't know how light they should be in comparison.

Thanks, I figured since the plants were still growing pretty vigorously whatever problems I'm having couldn't be that bad, but I didn't want to let get worse since I probably don't have too long till flower on these strains.
