ktkoistarted grow question 5y ago
What kind of deficiency causes small white spots on the leaves like this? Also on the lower leaf it's a bit mottled and yellow. I think it is two distinct problems.

Spots : Could it be bugs? Yellowing leaves : Make sure you don't over wet you soil. Don't water if the pot is still heavy.

Suspected Calcium Def?Think this might be the start of a calcium deficiency. Only on two of the older leaves and in similar spots on the leaves. These leaves may have also had some water on them after the last watering. Tried to remove it as best I could. Any thoughts?

Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on AutoWeek 8 (flower) top leaf tips are reddish and the leaves are more yellow than green. Does this mean that my plants need more nutrition? I am using Jacks 3 2 1 for two autos and using it at 65% strength (650PPM / 1.2EC). Should I goto 100% at 990PPM / 1.9EC or 50% to 550PPM/1EC

Deficiency?I've noticed a few leaves look like they have a deficiency, these are lower leaves from the first nodes. Have I got a deficiency to worry about or is it leaf damage?

Top leaves growing up on 5th week of bloomHi folks, I’m a new grower and I have 2 auto plants on bloom. They are in the 5th week and I noticed the top leaves are growing up. Can you say me if that’s normal? I’m using the sensi bloom, big bud and bud candy on soil one time per week. The ph of water is 6.4.

Each plant seems to be suffering from some sort of deficiency/lockout. I thought the 4AM & 3BOG looked hungry but no improvement after 2 days. Sour Stompers still losing leaves but their buds are MUCH fatter and frosty than the other 2. Maybe just different flowering times.

Missing CotyledonCame home from work and 1/2 of one of my cotyledons is missing! Do you think this plant will still survive/produce? I’m doing an outdoor grow so I expected pests but did not expect them this early in seedling/early veg. Should I spray with neem oil this early??
