Is this a nutrients problem

Nutrients
1

Hey forum, This is my first indoor grow and I am running into a problem. It looks like some sort of deficiency I can’t seem to get a hold of.

  • What strain, Seed bank, or bag seed. GG#4 clone from dispensary.

  • Method: FFOF and worm castings at 6 to 1

  • Vessel: plastic pot 3gal.

Water Ph at last feed (3.5g/gal Jack’s bloom booster and 5ml Botanicare cal-mag) was 6.80, ppm 657, EC 1315. Runoff was at pH 5.78, ppm 370, EC 740.

  • PPM/TDS or EC of nutrient solution if applicable

  • Indoor or Outdoor: indoor 2x4x5’7" closet.

  • Light system: viparspectra p1500 as of now 30" from canopy plus two corn LEDs at 60w each.

  • Temps; Day, Night: day 79-81deg; night 73-75deg

  • Humidity; Day, Night: day 60-62%; night 53-55%

  • Ventilation system: one 6 inch fan blowing from the top down ongoing.

  • AC, Humidifier, De-humidifier: no ac, small humidifier, no De-humidifier

Last fed yesterday morning. Problem started about a week and a half ago. Dec 12. I did a pH flush at 6.50 with 2 gal of water. After flush pH was at 5.90, ppm 259, and EC 403 runoff. I’m at a loss not sure what to do. If some one could help it would be much appreciated.

Welcome to the community!

Have you been giving cal mag all along or just on the last feed yesterday? Looks like mag def. to these eyes.

Started with the cal-mag at 1.5ml/gal on Nov 28. Then upped the dosage to 3.5ml until Dec 9 feeding twice a week. Dec 9 up til now at 5ml/gal. Thx for the reply @Eagles009

You’re welcome, based on the look of the leaves, the location of the effected leaves, and that you just recently started administering a full dose of your cal mag I feel pretty good about that’s what you’re looking at. Plenty of more experienced growers than me around here if they see something different they will chime in. Nice plant! Just a note the damaged leaves won’t repair themselves you will want to look for spread of the condition or lack there of on new growth.

Thx. I will stay with the 5ml of cal-mag per feeding. Thought I was giving too much at one point.
