Yellowing help.

Hi all,

Haven't been here in a while, actually had to get a new account. I'm back in the tent and am noticing some potential issues with my plants.

I am using a SP-SF2000 light at 75% with Coaste of Maine Stonington Blend(lil overpriced..I know). I germinated seeds on Oct. 1 and gave them a watering/feeding with Nector for the Gods(0.5-0-0) last week since I "noticed" the yellowing and thought it might be an N problem. They seem a little droopy but it may be because I watered a little too soon on the last go around. I wanted to install the Blumat system before a trip.

Does this look like a Mg or N issue to anyone in the group? If so are there any suggestions into simple measures to double check it? I do not have my PPH meter yet, so there are no readings to provide. The plant has been watered with PH ajusted distilled water that gets oxygenated via pump/stone.

Any help would be greatly appreciated. Good to be back!

I water them 3-5 days but mainly go on when the soil feels dry. They're in 3 gallon bags so they don't seem to require frequent watering yet.

I was doing research and distilled seemed like the best available, other than RO, which is hard to find bottled. I'd invest in a RO filter if this hobby was more frequent. Hopefully it will be.

Water/feed more. Your soil looks like you are only watering in spots. The WHOLE pot needs to be moist when you water. You will get dry pockets.

I am using a simple watering can with a skinny stream type nozzle. I try to go around the entire pot but I can see what you mean. I was worried about the nutes I'm adding because of the soil blend already containing organics. I was also thinking that the "droopy" bottom right plant on the picture zoomed further out was a result of thick soil moisture but I'm sure there are dry pockets now that i think about it.

Thanks for the info. I'll adjust my approach.

Plastic milk jug, very easy and effective. 3/4 to 1 gallon a plant. I run 7.5 gallon pots for photos and 5 gallon for autos. 7.5's get 1 1/2 water, 5 gallon get 1 gallon at water. What's wrong with your tap water?

Lol, yeaaaaaa, definitely underwatering when seeing how you do it. I only have a PH meter and read that tap water can be toxic for the plants. The PH is in the 7s but I also have PH up/down if needed.

Is tap water fine without knowing anything outside of PH? Would save me money on this water.

You want to let your tap water set out 24 hrs. Then your ok. Look into ph perfect if you feel you need. But you don't need distilled water.

A 3 gallon bag should take 1/2 gallon of water or feeding. Drawback to SCROG is being unable to lift the container regularly to check weight.

Ahhh okay. You definitely helped put me on the right track. I'm also going to start logging more of what I do in this grow for the future.

Thanks for the help.
