If you don’t have a growlog please answer these questions.
What strain are you growing? Is it Auto, Fem or Reg? Feminized Photo Period
Are you growing Indoor or outdoor? Growing in a 120x60x180 tent
Are you using nutrients? Which ones? How much? Advanced Nutrients Starter Kit and I try use half or less the recommended dose.
I have a fast bud Gorilla Melon hybrid which is in week 7 of veg. Not sure why the leaves are so light green. Have checked ph run off and seems to aligned to ph level poured in.
welcome to the community and hope your doing well. at first glance itt kinda looks like she is low on calcium, have you been feeding calmag at all by chance? normally when the fade starts from the top it indicates a mobile nutrient deficiency where as if it starts from the bottom up normally a nitrogen deficiency. this is just an assumption based off picture but totally could be something else and im sure a community member will chime in and correct me. hope you enjoy it here with us and if ya have and questions or concerns dont hesitate to ask the community cause there are lots of helpful, knowledgeable and friendly people here
Many Thanks and no have not fed her calmag. My concern is she has stunted and has nutrient lock out. I checked the ph and that looks fine so not really sure what to think. The. leaves did start to lighten from the top but have noticed that at the bottom there are a couple of leaves with yellowing spots and brown spots.
This morning I gave her 2 litres of ph 6.5 water cause she had not been watered or fed in about a week.
If your ph in and out are roughly balanced its probably not a lockout situation. As @Smokey101 suggested it could easily be a bit of calcium deficiency starting to present itself.
Will try adding some cal mag . Odd thing is planted two autos alongside this plant, not a great idea but here we are, and using same potting mix , with same fertilizer have had no issues. The autos are in 4 th and 2 nd week of flower and for the strains they are, look fine.
Welcome @FanofMrOctober With these symptoms, I would also suggest adding CalMag. CalMag is not a mobile nutrient and cannot be translocated by the plant. Although some is contained in the soil, the supply does not last forever, and at the latest, at the start of flowering, the dosage should be increased to meet the growing demand.
My experience with autos is very limited but they tend to require a little less nutrients than photoperiod plants meaning they might not have used up the initial supply of calcium and magnesium that was in the soil. Adding a bit now or at least having it on hand for the autos probably wouldn’t be a bad idea
