Pale bottom leaves and shaky stem.

Plant is roughly 3 weeks old. I have given it 1/4 the recommended neuts. pH is at about 6.2. I have plenty of lights. Temps vary between 65 degrees at lights off and 85 degrees with lights on. The bottom most leaves (approx. 2 of them) are starting to turn a pale green. Leaves are pretty small. Approx 1 inch in length. Do you think this is the start of a nitrogen deficiency or lack of lighting? I will be sure to be monitoring this very closely.

Another concern of mine, this one more severe, is the fact that the stem is incredibly wobbly where root meets stem. It feels as if it could topple at any moment. The other 3 plants are doing incredibly well and do not suffer from any problems of any kind at this point. I am debating whether or not to stake it and bend a paperclip to help keep it upright. Has anyone else ever experienced this and does anyone have any reasons for a cause and viable solutions?

Here are some photos of the plant in question.

Looks a bit like a nitrogen deficiency, did u use ferts in your soil mix?

The soil was premixed. Picked it up at my local garden center. Do you think it is old enough to increase the nutrient solution? Like I said I watered it yesterday with 1/4th the recommended dosage.

I'm starting to think it might be over watering or to much nutes, mabey a lock up! What was the NPK value for the pre mixed soil u used? A lot of them come fertilized with a high nitrogen % & by adding 1/4 strenght nutes u may be giving them to much.

The leaves were pale before I added the neuts.
Fertilome Ultimate Potting Mix

Is what I am using. The bag does not have any NPK information on it.

Just googled your soil & it has slow release ferts in it already! Try just PH'ed water for now & see if that helps, here's a useful thread as it may be another deficiency.

id say overwatering, also. let the soil dry, and see if the leaves perk up. raise your lights an extra couple inches to take less light stress to overcome the water imbalance

The leaves appear to be drooping because I have a 2 foot box fan pointing on them to keep the room cool. I didn't turn the fan off prior to taking the photograph.

Here are some photos of my other plants for comparison. The white residue is from pH balanced water that had sat and dried on the leaves. Nothing of concern there.

Over night the tips of those pale leaves has become very dry and brittle. The problem is still isolated to those 2 leaves alone. No other leaves are showing any signs or symptoms. No neut burn on any leaf tips and no other leaves are pale in color.

It appears as though this problem was caused by a lack of light. Plant appears to be doing well and growth continues to be strong. Thanks for you help and opinions.

Good work bro! Hope all goes well!

Thanks man. Keep an eye on the thread in my signature. Ill be updating it as frequently as possible. Thinking of buying 4, 4 foot T5 fluro's. They are kind of expensive at 35 dollars a pop but they do include the bulbs.

Subscribed bro! More light equals more bud! Go for more lights, u won't be disappointed!

I know but I don't really have a extra hundred lying around.
