New with questions

[JJJones215]

Hey guys new here and I have a question. Probably dumb but I’d rather ask then find out the hard way so I’m running a solistek a1 light and the bulb I have for it gives off a yellow color and I’m wondering if I can use this bulb at 600w to veg my plants . I’ve heard that for veg it’s better to have a light with more of a white / blue color to it and I don’t want to hurt the plants or send them into flour early I’m under a 24 hour light cycle at the moment using mills full line Thanks in advance

They will grow fine but keep the young plants like 4 feet away at first. 600 watt hps is very intense and ventilation is very important. 600 watts is hot.

They will just grow stretchier and taller under hps whih has a strong red spectrum. With metal halide or another lamp woth more blue in the spectrum they grow leafier and stockier. Shorter.

I like to veg under a 7000k MH and flower under a HPS for the reasons MiMed mentioned; shorter stockier plants.. But you can absolutely both veg and flower under just a HPS.

How old are the plants) ...how many plants?

600 watt light is for flowering, are you planning on throwing 600 Watts of light at the floor with a few tiny plants?

 

[JJJones215]

Sorry I’ve been busy at work and forgot to check back with you guys . So there are five of them and they are in week two of growth phase and I’m running a 24 hour light cycle. The light is about 4 feet above them and my temps very between 70-88 degrees with humidity at around 40-50%. Right now I’ve got them on a light feed I’m using the full mills nutrient line and adding cal mag to that.

 

[JJJones215]

They seem to be liking the 600 watt a lot but I’m seeing slight yellowing and curling of the leafs and I’m wondering if I’m under feeding or over feeding and what I need to do to correct it. Or if it’s something else completely

 

[JJJones215]

As you can see the plant on the left is happier than the one on the right and they’ve been given the same food and light and live under the same conditions. I’m just wonder what I can do to help them out

 

[Dirtbag]

To be honest they look a little overwatered. And that humidity is a little low for veg. With low humidity they will transpire more so you have to be really careful with feeding young plants. What have you fed them? Are you adjusting the solution with ppm and ph meters? What are the numbers?

See if you can increase the humidity any, sometimes you just need to reduce the temperature by turning the lights down a bit if possible. Let them get good and dry before watering next and skip the food on the next feeding, just give them straight water.

 

[Dirtbag]

Also it's easier to diagnose problems with pics taken in natural light, FWIW.

 

[JJJones215]

I’m ph’ing the feed to 5.8-6.0 and I’m using mills full line . have a humidifier but it’s not working very well atm. I need to buy a new one I don’t have a Ppm meter at the moment but I do have one on the way via amazon so I’ve been doing a light feed to try and not over feed them. I feed once a day I’ve heard hanging a wet towel in the room would help raise humidity I might give that a try. And I feed nutes 6 days a week and water on the 7th I’ve used a bat guano “tea” before with good results for the 7th day flush but I just moved to Oklahoma from Oregon /Washington so trying to find everything I was using back home here locally has be difficult as the nursery around here only carry select stuff.

I appreciate the knowledge and feedback!

Are they in coco? It looks more like promix.

If promix or peat based Id first stop with the daily watering. Water once every 4-5 days, or only when the pot feels very light. And while they are young feed only on every third watering. They dont need much when they're small and you've very likely overloaded the soil with food.

Since they are already watered daily you may as well rinse that that soil a bit with a good heavy watering of plain water with plenty of runoff before letting them dry out for a week or so, until they need more.

And I would feed closer to 6.5 when you do feed. 300ppm or so. Your soil may be a bit acidic with all the feedings.

I’m using ocean Forrest potting soil from fox farms, so I should flush them out next time I’d usually water/feed ( 18 hours from now) and then let them dry out for a few days or should I flush them now and let them dry for a few days?

 

[WankirA]

Welcome @JJJones215 , dont worry about asking questions: if you don't know, it isnt a stupid question.

 

[Ina]

Leave them dry much ,much more,water them less often from now on,lets say every 4,even5 days depending on how dry they are at that time in your conditions.Dont try to increase air humidity with more watering in the soil!If you flush them now or after 18 hours(too soon) you will drown them again.Water/dry cycle.They need air for the roots,some drying,a lot actually.First wait them to dry out almost completely.Than do what you have been suggested or whatever you decide but that is the main problem.They stay constantly wet.

I agree too often watering and those little plants need no additional nutes with ocean forest.

Also the light is likely too close.

I disagree with humidity. Around 50% has worked for me for years.

And above 80 is too hot.

50% will work just fine in most cases if you are gentile with food, like you are. But in my experience plants noticably like it better closer to 70% in veg, I've seen this with my own grows, and it's very common in horticulture growing most other plants as well.
Low humidity if you are new o growing and heavy handed with feedings can be a total disaster. Esecialy if it's on the warm side.

I have only seen problems below 40% in my method. I have been balancing rooms to average 50% for years. I never have problems at 70% but fear mold and mildew here in michigan. Pm comes fast here.

They sell moldy weed like its normal out here. I run a lot of dehumidification.
