Hey, there are pictues from two different plants - both White Rhino. I grow in soil, and the plants are around three weeks old. Ive fed them Biobizz Alg-a-mic and BioGrow. I water them every 2-3 days. I grow under a 400w HPS.

Plant one:


plant two:


I havent noticed the problem before, so I think it just popped up over night. I could be wrong though.

Thanks

how stable is yor pH, pic 1 looks like early signs of pH fluxuation, and 2 looks a little N def. flush them really well, then let them dry out COMPLETELY, then light feed them

What I see are the beginnings of Potassium shortage in the first picture, and Magnesium shortage in the second picture.

I don't have enough information to diagnose anything. Temperature? Humidity? pH? Age?

Could be low pH. Could be Calcium build up from hard water. Could be high heat and low humidity. Could be salt build up.

More info man. I'm always perplexed at how little information people provide to get help for their sick plant. It's like going to the doctor and saying "My stomach hurts" and then not saying another word. Is it colon cancer? E. Coli? A broken rib? A swallowed coin? A gerbil?

Get it?

Well I'll tell you right now it's def not the HPS. And yes, you can use a HPS all the way from seed to bud... Not 100% recommended, but absolutely not the problem here: looks to be maybe a PH lockout or a Mag def. ... Like Snow Crash said, need more info/pics...

The temperature varies from 77-84F.
Humidity varies from 35-55, usually stays at 40.
The plants are 22 days old, I started LST'ing them recently.
I've fed them twice with alg-a-mic and biogrow.

The plants were looking real nice and green until a few days ago, when this started happening.. Also, some bottom leaves got raped and got retarded from the start - and it didn't affect the other leafs.
Some leaves have started curling up, they have wind from the fans blowing at them 24/7 - is this the problem?




Its a little dirt on the leaves on the picture above. I tried to ph-test it but i failed,lol



Thanks for the replies, I really appreciate it

It is getting worse, and it seems like the growing has stunted a bit. The leaves are very crispy too. Also, the leaves are hanging downwards..








I think it started after I fed them biogrow and alg-a-mic, I have a very nutrient-rich soil..

After what I've read, I can see magnesium deficiency and maybe a ph-fluctuation. I did a ph-test, and I got a very light green color. I guess that indicates I've got a PH between 6-7 which is perfect?


And I doubt I'm overwatering them..The soil is always very dry before I water them.
