Brown burnt tips on smallest leaves

Little_Potstarted grow question 4y ago

Today I noticed that smallest leaves are getting brown tips. Yesterday I sprayed her with diy insecticide against thrips(soap, alcohol and h2o2). Could it be light burn or nutrient burn? She grows in bio bizz all mix which is heavy fertilized, and gets no extra nutrients.

Have to agree with Organoman here... either use some Spinosad or Dr. Zymes or SOMETHING that is made for spraying plants that does NOT contain alcohol! Both Spinosad and Dr. Zymes will take care of thrips (and spider mites and aphids and and and) and both are organic. If you get the concentrated versions, mix them exactly as directed... Good luck!

High, This is caused by nuteburn. It is better to start with lightmix. I do always use BioBizz lightmix this contains enough nutrients for 2 weeks. So you can control the nutrients after 2 weeks. The Allmix contains nutrients for the first 6 weeks so you can not feed them as you wish for the first 6 weeks. I would just keep giving plain water till they are 6 weeks old and then start to build up the nutrients. Happy Growing! 😋

Burning from being sprayed with your home made insecticide, plants can not tolerate alcohol!

Nutrient deficiency which kind and/or light burn?Do I have some nutrient deficiency or light burn or maybe both? Looks like maybe P or K? I changed my light to a HPS and the plants grew much closer to the light so could be too much PAR/heat so I raised the light. I also had started to add Cal-Mag to my feed just before.

Leave tips brightening Hi, I noticed the tips of leaves on younger parts are turning brighter, one tip already turned brownish. Is it because of nutrient burn?

Please help. Last plant died exactly like this. Yellowing drying leaves from the bottom on all fan leaves while shoots get stunted / eventually affected.Transp recently from 1g > 5g. Seemed ok at first day after (no wat) then leaves started rapidly yellowing / drooping. Tent is fairly small 40x40x120. Could it be the heat ? Also took out humidifier but still in same room tent vents. Is Canna Pro Plus watered between 5.8-6.2 ph ?

Leaf issue in Wk 6 Hi I am having a leaf issue late in week 6. It’s been coming on a while. I’m wondering if the ph is out or too high ppm. 7 gal pots in a Scrog, it’s hard to test runoff. I’m starting to flush now so does it matter as much as long as ph is good? More wondering for next run. Thanks
