need help. don't know what is wrong.

I am growing in soil under a 300 watt LED. All plants are autos. I'm using advanced nutrients 3 part PH perfect nutes. Don't have a pH tester. Used LST to break apical dominance. Very new to growing. Here are pictures of the plants. This is a GYO Tangerine auto.

This is the older 2 fast 2 vast. Same age as the tangerine. It's very droopy and the flowers are much slower growing.

This is the younger 2 fast 2 fast. See some definite calcium deficiency. I think. Removed the worst of the rusty leaves after taking the photo. Need advice with all. Thinking I may have to much perlite in the soil and it's not holding the nutes.

the droopy one looks dry, you're using hydro nutes for soil, soil is a different game. I'd use those nutes in DWC next time you'll have an easier go, that's the brand i use its super easy with DWC. Someone with more soil knowledge can help better but most likely they'll need a flush and gentle restart. The droopy one is either almost dead or just needs more or less water IMO

I see some Potasium deficiency, Nitrogen deficiency and Magnesium deficiency on different pics different plants(?)

(The leaves you think were Calcium issue, that was potassium I am fairy certain)

(Lower leaves getting pale with that banded look between the veins, Magnesium issue.)

(The overall light green hue of the plant, Nitrogen issue as well overall.)

You may have a pH issue inside the medium, or
I think you are over watering most likely.

look overwatered and deficient which may be caused by overwatering. Dont remove deficient leaves untill problem is sorted.
1. Pulling leaves lesens resperation which will make it take longer to dry out.
2. The plant is useing the affected leaves like "nute batteries" pulling from them to fuel new growth. If you remove them before problem is fixed it will just start pulling from different leaves

You need to check ph... multiple deficiencies is usually nute lockout from improper ph..

Advanced suggests not altering the ph when useing there ph perfect line.....with that in mind it is made for hydro not soil

What if your water source is 4.0 or 8.5 ?.. no such thing as ph perfect.. Testing ph is a must..

Never mind advanced dosnt suggest that......if your water source is that far off 7 you need another water source. Besides advanced also suggests useing ro or distilled. Keep in mind if useing any product on earth differently than the manufacturer suggest you will get different results

I don't have a pH tester. Can order one but it will take a week to get here. I asked AN and they said though the nutes are designed for hydro they work well in soil.

You're overwatering, which will show everything you see.

I use distilled water for my feeding and watering. I will keep trying and find a good PH meter.

Ok. I'll try watering less.

Most do just at a lighter amount. Cyco is a hydro nute. They ask for 3 mil a and 3 mil b. In soil its droped to 2 mil each. If your in a good potting soil and useing a good clean water dont worry abought ph. Im almost positive your deficiencys are from over watering

as someone who has successfully used these nutes in hydro for years with no ph meter i have to insist you check your soil ph, the nutes may work in soil but id guarantee the dynamics are different, for instance, in soil you won't feed every time, you'll definitely be susceptible to ph swings if you overfeed because soil is not the same as inert or aqueous media

I'm looking into a DWC setup for next grow. Height is an issue for me. I talked to AN and they said that it would work fine as long as there was good runnoff from feeding. Fed last night with one quart each. Distilled water and full strength nutes. The droopy one is looking much more perky. My plants may be drying out faster than I realized.

You're overwatering man. That's what is causing lockouts. What are you using for a medium? If your pot feels heavy don't water. You want it to dry out befor watering again. Wait until your pot feels light then water or feed depending on your schedule. You should really check your ph too, I don't care what AN says I'd still be checking ph but that's just me and to each their own.

Had a hard time finding anything but miracle grow soil. Finally found regular soil with no nutes at the dollar store. Added about 30% perlite for drainage and aeration. I will water less. See how it goes from there.

Do yourself a favor and get a ph meter. Some are not expensive and will help you out. If you are in a bind you can even get one of the liquid test kits to give you a general idea of where you're at and they're cheap.
