I would water it even if 750 after calmag ... check ph tho to match your medium. Mid / later veg ppm can fall from 600 to about 1000 normally.

Just remember... if you know the ppm / ph “going in “ then there will be no need to check runoff. The idea is to match ph of medium .
Everytime you water heavily , you sometimes LEACH the medium. Plant will only take enough it wants , this way you create a wet/dry scenario instead of flooding the container .

Leaching medium is usually done because of overfeeding and buildup of salt.

I phd the water before watering to 6.5 and the ppm was around 400. The first plants run off was 7.5 ph with a ppm of 1200. I kept watering until the ph got to 6.8 and the ppm got down to 600. I repeated the process for all the plants, the ppm run offs varied from each plant from 700-1200. PH of each plants initial run off was consistent mid 7s. Got all the phs down below 7 for all 6. Hopefully ill see some improvement within the next few days.

Hey all, first grow here so any help is appreciated. I've got 6 autoflowers going right now, all different strains. Out of the 6, two look like they're having the same issues. Droopy leaves curling downward. The other 4 look pretty perky and healthy from what I can tell. They've all been on the same watering schedule thus far, only watering when the pots feel dry by weight. I'm at day 33, so far I've watered 8 times within those 33 days. The first 3 or so weeks was just phd water with no nutes. On the 6th watering I gave them their first nutes, Cal mag and GH flora 3 part series. 1ml cal mag, micro, grow, and 0.5ml bloom per gallon of water. About two days after this nute watering I started to tell two were drooping, while the other 4 looked perky. Two waterings later of just plain ph'd tap water with really no noticeable improvement.

My setup is a 4x4 tent with 3 LED lights, two are HLG 100's and the other is a vivosun blurple 600W (230W actual) all at 20ish inches from the plants. My temps are on the lower side I believe at 69-70F when lights are OFF and 74F when the lights are ON. 20/4 is the light cycle. MyRH stays between 50-60%

These pictures are all of the same plant. but the 2nd one looks pretty much identical to this one so I didn't bother getting close ups of that one. Note that all are pulled down due to LST and the first picture of the whole tent was taken a few minutes after the lights came back on so the four healthy ones may seem a tad droopy too but they perked back up fine like normal.

One . Organic soil should not be watered to run off. It washes mycrobial life out the bottom. It doesn’t look like the soil is too hot.
Two. Organic soil holds lots of water. To me it looks like they have been drowned and then left in too cold of a room and on the floor.
Growing with led requires a rise in ambient temp in your room to promote good growth. Right now your room is too cold. Needs to be at least 80. Your humidity is good but wet roots and wet cool air will make all your leaves droop.

Pick your temps up. Don’t water till your pots are light in weight. Move lots of air around. And they should pick up after a week. Be patient.

As far as watering. I’m growing in 5galon grow bags and water 1 gallon every 3 to 4 days in a room at 80-83 deg. I watered at first to hear the soil start to gurgle and then stop. That’s how I get to know how much water my soil will take. Take it slow.

Serious question if I don’t water till run off how do I check my ppm of my runoff? I’m asking because I do auto flowers and I don’t have an exact feeding schedule. Checking and monitoring ppm is one way I tell if I’m overfeeding.

my temps are cold and I struggle to find a way to raise them safely. Lights out can get down to 65F and lights on only get to 70-71F. 20hrs on 4hrs off. I have two golden rod gun safe dehumidifiers which are just heating rods but they dont raise temps enough. I have a small space heater laying around but I dont know if I trust putting that in the tent for safety reasons while I'm not around. Do others use space heaters or is that a bad idea? Any other tips on how to raise temps without spending a lot of money?

I use a space heater. Small 600w with thermostat so it shuts off. Or look at panel heaters on amazon. Look for low wattage. That will do in the small space. Cheap and easy.
