After watering today i noticed my leaves are looking very serrated and sides are sticking up. What could this be?
Why do my leaves look serrated?

Hmmm... looks good, but the serrations pointing up could be from heat stress. What's your temps?

Temp stays between 72 and 76 degrees. I have had a calcium def ive been working out and didnt add and calmag this watering but it happened as soon as i watered not even an hour afterwards. PH is 6.3 in soil.

Could be a ph problem, or a root problem then.

What's the light height? Maybe a lil light stress?

Weird they were fine right before watering whatever it is they reacted immediately. I read it could be a calcium def causes that? What if i take a half gallon water and add 1/2 dose of calmag do you think maybe thats a good idea?

2 bestva 1000s. 200watt from wall set at 24". I had lowered it last week to 20" but it started burning tips of top leaves so i raised it back up.

Early canoeing? Vpd? Put a fan on them, pull air out if space as needed.

I don't believe it's C def., but that doesn't mean it's not. Could be a humidity problem. Do you have a fan blowing on it?

I checked the PH with just a small amount of runoff after watering today it was 6.3. Using spring water PH set to 6.3 its been the same since i started the grow. Im at almost 6 weeks in grow now and havent had any issues with PH.

I have a fan set on them as well. Temp is at 73° right now with RH at 46%. All that stays steady im stumped as to why it happened so fast.

Yea i have a fan blowing and a 4" ventilation setup as well. Humidity stays between 40 and 50% my room is very consistent with temp and humidity.

They are just to close to the light. Ambient temp is ok but they are hot under the light. Time to go up another half a foot. The edges turning up is to help them transpire more, they are hot so trying to go thru water as fast as they can.

If you have a fan blowing on the plant, it could be causing it to over transpire.

Your lights didn't burn leaf tips, nutes did
Light burn looks completely different

Ok i have it set directed toward it but it only moves the leaves very very little should i aim it up a little so it isnt straight on it? Its a small fan the room is only 2x3 with the ventilation it has pretty good airflow.

See ive been back and forth with that. Shes in black gold organic soil and i havent had to add nutes yet but i had one seedling die from to much nitrogen "assumption" and had nitrogen problems with my other 2 as well and calcium def... This soil is horrible. Im ready for these girls to be done with run and start fresh in something else.b

It prolly wouldn't hurt to try, but do one thing at a time and wait to see if there's a change. If not, try the next thing.
