Well pH causes nutrient uptake problems so most problems that manifest could be the result of bad pH. Whenever there's an issue, start with checking pH and EC if you can.
That said, it looks like a nitrogen toxicity and perhaps a calmag issue as well.

If you have no EC pen or PH meter flush soil and then 're water with a ph 6.4 light nute solution should help stop anymore problems from soil ... this is a last resort

The plants in my system do not
do not grow up evenly and brown deposits on the leaves. Water temp was high 21 degrees and has now been lowered to 19. Ph 5.7 and EC 0.6.
Nutrition: No nutrition because I thought brown leaves could mean overfeeding. I've added 4 pictures #somethiWeek 2

Leaf problem, insects ?Plant is approx 60 days old.
I have found and washed off what look like insect eggs under some of the leaves but have not seen any webs or moving creatures.
Is it insect damage or could it be fungus.
I have 2nd plant that seems unaffected.
Mainly lower older leaves affected.Leaves. Color - Mottling

Hi there, does anyone have any idea what the slight mottling is on the leaves of two of my plants. There are close-up pictures under Day 27 in Week 4. The discolouration is present across multiple leaves, but seems to only be happening to two plants out of 8. Thanks!Week 4

Should I remove foliage affected by deficiency, or just let it ride?Autoflower started showing sign of deficiency at week 8. Assuming CalMag, as I filter my water and affected area is new growth at top of plant (see pic).
1) Can someone confirm CalMag deficiency or something else?
2) Should I remove affected leaves or leave them be?

Am I right that the brown spots on one of the plants are an indication of calcium and/or magnesium deficiency? I ordered some CalMag Extra from Advanced Nutrients; should arrive soon. Would/should I apply this only one time or add to the regular feeding schedule?Week 7
