Droopy, Yellowish, Spoty Plants Help Please!

[FrayedKnott]

Not sure whats going on plants were doing fine until a week ago. They were perky and thriving, just been watering them, haven't given any nutrients yet, they're in new soil. They were repotted from cups to 1 gal containers 2 weeks ago.

The strain is white rhino
grown from seed
they are 5 weeks old
plants are about 5 inches tall
soil is FF ocean forest
in 1 (one) gallon container
600 w MH light 24/7
light is approx 6-8 inches above
Temp are 71-73F Humidity is 35-40%
PH is 6.9-7.1
3 6 inch intake fans
8 inch & 4 inch exhaust fan each w/ carbon filter

From looking at the sticky's, maybe there is a Magnesium or Manganese deficiency problem. Don't want to do any more harm without some verification.

There are 4 plants total, with various photos to help diagnose.

Any insight to my plants problem would be greatly appreciated.

They look overwatered to me but your ph should be 6.5 in soil. Let the soil completely dry out then water with 6.5 ph and see if that helps.

Hello FrayedKnott

Over watering.

How often are you watering them?

How are you checking and how are you deciding that it is water time?

I agree...i run my PH at 6.5...Like Bomb said..be sure to let soil dry completely..bone dry..and then still wait a day:giggle: they will be fine..start a light dose of nutes as well..IMO..take care and be safe:bolt::bong:

I'm watering every 2 days or so, when the soil is grey and feels dry to touch 2 knuckles deep.

I'll wait another day to be sure it's good n dry.

Thanks for the help and responses!

In that case i'd say it's just a ph problem and when you lower the Ph you'll see positive results.

Nitrogen Problem

A light Nitrogen fert and foiler spray should help them wait for next water Id go with the nitrogen feed then see if foliar wont pick them up
