Hey guys. I'm having some issues as shown below.

Also slight Curl on the leaves as well.

PH 6 ( I moved it up from 5.8, I feel like it was a bit to low)
Room Temp 76-78
Humidity 50-70
900 PPM
Autoflower Early miss from kingcropseeds
RDWC SETUP

Under LED lights
Plants 3.5 weeks old

This is my first grow. So I think its Cal/Mg deficiency.

Give me your opinions please.

My ph has been at 5.8 for weeks, 6 is max for me, 5.7-6 is my drift. That looks like maybe some calcium and some phosphorus, possibly more, what are you feeding it, you didn’t mention any nutrients.

Sorry, Its RO water just with the General Hydroponic 3 part blend.

How old is that water? When did you add or topup anything? What schedule are you feeding? Could just say add calimagic and see what happens in a couple days. Can see purple stem and the one leaf looks like phosphorus def, the spots look calicum, I don’t deal with pests a lot but always check for pests or past signs. Some N even maybe seeing some mag in there. If your not having ph issues or heat issues on the roots..

22-23C, I did buy some reflective material today to put above bucket, and moved my res bucket out the tent.

I completely switched over to a new nutrient line made in Canada. Invitation plant products. Its got a bigger feeding chart and is 7 parts for Veg stage. . And lowered my PH to 5.5. The nutrient line calls for 5.4-5.6. I actually noticed plants get weaker when I moved up to 6. So hopefuly that was part of the problem.
Im going to get a AC unit as well so i can have perfect temp outside my tent.
@J232 , you think between higher PH and water temp that could be my problem?

Hey I'm a noob to growing as well! What I've learned was water should be from any range between 6.0-6.5PH feed water. This chart explains what the plant gets at this range, notice I said range and not a specific number.
Here check this out:




I like to PH my plant @ 6.2 now as far as water temps its 71 Fahrenheit.. anything colder and the plant can go into shock. And for temps 77 Fahrenheit lights on and 66 lights off. Humidity for a plant at your stage 66% lights on and 60% lights off. I'm grow organically so all my nutrients is in the medium alone with some tea's I brew up.

Attachment is my girl! She's trying to recover from a magnesium or nitrogen toxicity!

If it gets to bad you can always flush her so you get rig of whatever is doing this from the roots zone. But that's last resort do some research on flushing cannabis plants first.

Good luck!

New water, fresh nutrients and lower res temp, I’m sure they will be good to go. Just make sure there’s no signs of pests anywhere and make sure your roots don’t have any rot. I would not change the ph that low myself, that swing will prob be seen in the plants as well if you did. Google nutrient availability according to ph for cannabis.

Also just in case you may not know,water your plant till you get 20% runoff water and wait till the pot feels light again before watering or just do the finger trick stick your finger into the medium till the first knuckle and if it feels dry then its time for watering.
