GR0WERstarted grow question 2y ago
So, it is my problem. Few leaves on the top of the central plant. Idk, what kind of pathology is it and how to kure it.
I guessing overheat, but temperature sensor shows 25°c max, lamp to plant distance is about 30cm.
Also, they aren't smelly no more.
Please, help

no pics so tough to say.. but could be light-related. depending on where your thermometer is, the temperature more directly under light could be higher, in which case heat can be a potential cause too.
3x2 tent? roughly? 300 watts is a lot of light, especially at 17" from canopy. unless your pushing co2, that's probably a good bit more than you need. so a little more distance wouldn't hurt.
plants look healthy, otherwise in the diary pictures, so just a matter of observing.

Tips curling upI noticed the tips beginning to curl up.
I did gave her bio grow in the last two weeks 0.5ml/lt ph 6.5 almost every watering i used bio grow.
I have another 8 plants of different breeds and none of them showing anything wrong.
I wander if its the nutrients or perhaps the light?

Whats wrong with this plant?Was water logged, transplanted into 95% dry soil to correct, soil with nutes in it.
I see:
Heat stress. LED light 2.2 ' away, raised the light. ( curling up )
Late stage P deficiency... green veins.
Can't flush, was just waterlogged, what to do? Water a bit with RO?

Leaf problem and purple stemsHi,
I have a problem with my auto.
I have purple stems and problems with the leaves.
The soil contains organic nutrients and mycos sometimes I add flowering boost from royalqueenseeds so I don't think it is P or K problem.
Is it a nitrogen deficiency ?
Thank you for the answer

First time growing/Need help in late flowerOver the last 9 days my plant has gone from happy and healthy to sugar leaves pointing straight up near the top of plant and drying and curling up on the lower levels. Is this from too much light or did I over feed late in flower? First grow/ no diary. Can I save or do I chop?

This margin curl appears to have spread from one plant to 2 of the other 3. So I assumed not pH, not lockout, not nutrient based. Roots all great. I've culled the 3 and there is 1 survivor doing well but what was this? In the diary I mention using Temprid FX, Neem, Spinosad.

My plants are suffering a Phosphorus deficiancy due to lockout due to low ph of soil. My first flush only helped for a while. As soon as the medium gets too dry damage resumes. what should I do? I went to check on them today and the amount of damage they took in 24 hours was bad.5y ago
