Hello,Three weeks ago the people of this forum helped me with nute burn. Now I have a new problem. I went on vacation for two weeks and had someone water my 4 plants. One of them is not doing well at all. I prepared water ahead, The PH was 6.5. I added 1/2 of the recommended Dyna-Gro Bloom. Two of the pictures are of the diseased plant. The other two are what the other 3 look like. The temps have been between 60 at night and 85 during the light hours. They are in their 4th week of flowering at 12/12.
If you do not know, or do not use something; Just say so = NA

What is the strain and type(unknown bag seed, strain name, regular seeds, feminized seeds, auto-flower, etc)?
Indoor or Outdoor? If outdoor, planted in ground or in a container?
Size of space (max height and area, length/width)?
Soil or Hydro? Type of Medium used? System type?
pH? Of the soil or medium (root zone/reservoir/run-off) and of the water and/or nutrient mix that is fed to the plant?
Type and strength of nutrients used? NPK? EC/TDS/PPM levels? Of what you feed it as well as what is in the water by itself and in the soil/medium (run-off), or reservoir.
Temperature? Day vs. night temp or highest and lowest temps? Root zone temps?
Magnesium deficiency, dose it with 1 tablespoon epsom salts per gallon of water.
Magnesium gets locked out of soil growing at ph levels of 2.0-6.4
Magnesium is absorbed best in soil at a ph level of 6.5-9.1 . (Wouldn’t recommend having a ph of over 7.0 in soil) anything out of the ranges listed will contribute to a Magnesium deficiency.
Strain: Budzilla feminized
Indoor grow
3x3’ area
Soilless grow, half perlite half peat moss/coco
I use fox farm nutrients, and did half the recommended amount, I give nutes once a week, roughly every other water, sometimes less.
pH is under 7
No CO2 or carbon filters, just fans that add circulating air.
Temps: 64-68 F - 64 at night, 68 all day
Humidity: 45%-70%
18/6 light schedule
T5 fixtures (for veg only)
Not many watts for lumens, but this is a first for any vegging plants.
And i agree with Will, looks like magnesium deficiency that chart will explain excess and deficiency side of things, and here’s another cart to help show what nutrients in excess cause the nutrient lock and should help get you on track to fix it, And A Nutrient Lock Out Could Be The Problem, temps during day should come up as well as night . Temperature at day should be 75-85f and night time 68-72f
And id say flush and try to reapply the nutrients a week later no early to make sure it’s flushed…reason for flushing is to wash excess salts out from left over nutrients plant isn’t using…then start her off with half of what your using
This is magnesium deficiency and can be taken care of if done as I had explaind above earlier. Case in point here is a pic’s from My Guide On Sick Plants.
