lipz92started grow question 5 years ago
Hello, since yesterday my plant started developing these weird marks on the leaves (day 20), this is my first grow, ppm around 220 and pH 5.5 to 6.5. Water temp 21°c and temp 28°c, any idea what might be causing this to my blue?

That is caused by your leaves laying on top of medium. Try to keep them off if you can. But nothing to be alarmed about. Everything you said is on point even 21c that is perfect water for hydro. Just be careful with nutrients cuz autos don't feed as much as a photoperiod. They use far less nutrients. I start autos at 1/8 strength and Max at around 1/3 strength of manufacturer recommendation.

Probably the Canna Rhizotonic , it’s not the first time that I see those weird marks with this product.
It can’t be over feeding at 220 ppm’s and pH seams correct. I would have think that the solution was supposed to be a lil bit cooler around 18°C in Hydro but I’m not an expert .

Can anyone tell what is causing these yellow tips on new growth on this plant?I noticed my DLI was around 42 at the top of this plant so the light may have been too strong, or it could be a nutrient issue? Using CoM Stonington soil, plant is 26 days old. Haven't added any nutrients to the soil yet.

What may caused the issuesChecked the runoff and confirmed 6.2PH and 130 ppm on water.
checked on my Tank and same was happening.
so gave a 603 ppm solution of cal/mag. Grow A+B perfect pH connoisseur, H2O2 at 5.8 pH.
Will await for results.
i think at week 3 theyre supposed to eat at least 600 ppm?
